Notes from EU Summit in May

The EU summit was right on the heels of the 700 series general release so it’s been a very busy time for everyone. The Z-Wave roadmap has major releases every 6 months and minor between them. Silicon Labs plans on a long life and improving volume shipments for Z-Wave and is investing in the technology to realize these gains. Attendance at the summit was up again with attendees from around the world.PANO_20190509_160327.vr

Certification costs recently went up but adding frequencies (countries/regions) is now just paperwork and free. The all important Certification Test Tool (CTT) was recently updated to version 2.8.4. If you are heading to certification with your new whiz-bang product you’ll want to test it with the latest version of all the scripts. The CTT is actively being improved so future releases will be even more powerful.

All 700 series Certifications must be Z-WavePlus V2. The logo remains the same but V2 raises the bar on several fronts. The main upgrade for V2 is that devices largely advertise their capabilities without the need for Hubs to write custom drivers for each and every device. Specifically, Configuration Command Class now requires the name/default/min/max values as well as some text describing the function of the parameter to be returned via a GET command.  However, 500 series are not required to support V2 but are recommend if you have the code space for it. For Hubs the bar has been raised significantly with Security S2, SmartStart and many interoperability improvements that will require some resources to achieve certification.

Expect the RF range minimums to go up from the current 40m (132′)  with the improved radio of the 700 series. The range requirement hasn’t changed yet but there are lots of discussions on the topic. Most of the devices I’ve worked on (over 3 dozen) have consistently achieved over 100m of line-of-sight RF range so I expect the minimum to probably double. This does make testing a bit more difficult as finding a location with 100m of open space can be a bit of a challenge, especially in winter!

Presentations

The presentations at the EU summit (and most of the previous ones) can be viewed from the Alliance web site. You need to be a member to gain access to them. My presentation (along with Axel Brugger) was a deep dive on using the 700 series and getting familiar with Simplicity Studio for developing end devices. Hans Kroner gave a similar presentation on developing gateways using ZIPGW/ZWare. While you can view the presentation online I highly recommend attending in person so you can ask questions and get straight answers right there on the spot.

Fun and Games

The members night was at The Beach which is an indoor beach games facility with lots of crazy stuff. Great food, Great music, Great games made for an enjoyable evening after a long day of stuffing information in your brain!

The US Summit was held in Austin Texas Oct 2-4

The US summit was held at the Silicon Labs office and at the nearby W Hotel in Austin Texas. Another excellent turnout with lots of informative sessions from technical training to marketing by leveraging the Z-Wave Alliance.

This is just a fraction of the turnout at the US Summit in Oct 2019

Interoperables are BACK

Mitch Klein received a Lifetime Achievement award from CEDIA a few months back. As the leader of the Interoperables band we had quite the show all to ourselves along with plenty of food, drink and excellent conversation. By far the most beneficial part of the Summit is the chance to talk to your fellow Z-Wave developers, marketers, executives and enthusiasts.

The Z-Wave band “Interoperables” are back with a wide repertoire of classic rock

Pilgrimage to the Z-Wave Homeland

I finally made the trip to the home of Z-Wave, Copenhagen Denmark. Z-Wave began as Zensyszensys-logo back in 2001. My journey with Z-Wave began shortly after that in 2003 when I was disgusted with my highly unreliable X10 home automation experiments. I just couldn’t get that X10 junk to work! It was cheap, but it wasn’t worth my time and frustration so I was looking around for other technologies that would be reliable. I experimented with several custom baked wireless solutions but quickly realized that wireless is really hard and complicated. Z-Wave caught my eye because it was a real mesh network and actually worked. From there I have continued to be impressed by the technology improvements always with full backward compatibility and wide choice of fully interoperable products from many manufacturers.

My purpose is to meet the engineering team and to learn in much greater depth the details of Z-Wave and especially the new 700 series. We have an intense group of smart engineers working diligently on the many aspects of a wireless system as complex as Z-Wave. One team is busy with the gateway specific parts of the protocol and the Z/IP Gateway and Z-Ware code. Another team is working on the protocol and solving very complex issues that we find are happening in the real world. The support team (of which I am part) helps customers get their products to market quickly by answer their questions and providing training. And of course there are the marking and sales folks who make sure you all know about the benefits of Z-Wave.

ZWaveCPHThe Z-Wave team in Copenhagen resides in this modest building. Danes love to bicycle to work or take the excellent train/bus system. Only a few travel via car unlike those of us in the US who just love sitting in traffic for hours. The food in Copenhagen is wonderful with plenty of international choices as well as the Danish favorites. My hotel room is more of a spaceship pod than a boring room with the Danish penchant for efficient minimalism. The view of the windmills in the distance and the quaint classic European architecture are beautiful.

Z-Wave EU Summit

The other purpose of my visit across the pond is to attend and speak at the Z-Wave EU Summit. If you are a Z-Wave developer, I highly recommend attending as you’ll learn about the latest Z-Wave technology and best practices to build robust IoT products. We have two technical tracks in addition to the marketing track. Meeting with your fellow Z-Wave developers to share your experiences and learn from theirs is the main value of the summit. The only way to get that experience is to attend in person. See my other postings about last years EU summit and the US summits to get a feel of what goes on.

The summit is next week in Amsterdam. Click HERE for more details on the summit.

Z-Wave 700 Series Announcement

The long awaited 32-bit ARM based Z-Wave transceiver chip has finally been officially announced. The 700 series announcement is on the home page of the Silicon Labs web site so this is a big deal for SiLabs and Z-Wave. The companies joined forces just eight months ago and we already have a major advance in Z-Wave technology.

Z-Wave 700 Press Image

What’s New?

The 700 series is a major improvement to Z-Wave for both consumers and developers. For consumers, the lower power and longer radio range means more reliable communication and longer battery life. For developers the main advantage is we’ve finally moved beyond the 1980s 8051 8-bit CPU with very limited debug capability into a modern 32-bit ARM CPU with full serial wire debugging capabilities. We can FINALLY single step thru code instead of having to use PRINTF!

700 Series Features:

  • Longer RF range
    • 150% in the US and 200% in the EU due to improved RF sensitivity and increased transmit power in the EU
  • Lower Power = Longer Battery Life
    • Improved semiconductor technology and a faster CPU yields significant battery life improvement and 10 year coin cell operation
  • Lower Cost – Worldwide Support
    • Improved RF blocking means the country specific SAW filter is not needed saving cost and making a single SKU for worldwide operation
    • No external serial memory is required and OTA firmware update is now mandatory
  • Easier Product Development
    • Integrated Debug Environment (IDE) with full ARM debug, single step, trace, and energy profiler speeds product development
  • 100% Interoperable and Backwards Compatible
    • The 700 series is fully interoperable with all mesh-networked Z-Wave devices all the way back to the pre-100 series Z-Wave devices

When Can I Get One?

If you already signed up for a free Beta devkit, then one should be on its way in the next few weeks. Devkits have begun shipping but quantities are limited and will take until the end of January before all the Beta samples are shipped. The Beta signup closed back on October 1st so if you missed the deadline you’ll have to wait until later in Q1 to request one from your Silicon Labs salesperson. The official “general availability” (GA) release is the end of Q1 at which time the datasheets, chips, devkits and software will be released at the 7.xx full release version. Datasheets require an NDA until the GA release.

You can get started today using the Simplicity Studio IDE and begin developing code and explore the SDK. The software is free and can be downloaded from here.

My Initial Thoughts

I’ve had a 700 series Beta DevKit for a few weeks now working with our Alpha release partners to get some early feedback. We’ve had some hiccups and the firmware needs more work but the silicon is solid. I have joined my 700 series devkit to my home and it communicates fine with my very early pre-100 series Z-Wave light switches attesting to the ongoing commitment Z-Wave has to be fully interoperable and backwards compatible.

Z-Wave Summit Fall 2018 Philadelphia

The Z-Wave Summit is usually held only once each year in the USA and it is not to be missed. I’ll give a brief overview of what was discussed at the summit in the short post below. But if you didn’t attend in person, you missed the most valuable aspect of the summit which is the chance to meet and talk to other Z-Wave developers. This year the summit was hosted by Bulogics in the city of brotherly love,  Philadelphia PA. Bulogics is a Z-Wave certification house so they know everything about Z-Wave and how to have a good time!

Summit Notes

The 700 series was officially “revealed” at the summit with many presentations talking about the new ARM based Z-Wave transceiver. The summit has over 140 attendees from 70 companies not including all the Silicon Labs and Alliance employees. This is the largest attendance of a summit to date and reflects the rapidly growing world of Z-Wave.

Matt Johnson, IoT Sr. VP, described the roadmap for multiprotocol chips which include Z-Wave, zigbee, BLE and Wifi as well as proprietary protocols. For the immediate term though the focus is on getting the 700 series shipping. The real key for Z-Wave is the interoperability and certification ensuring every Z-Wave device can communicate with every other device.

Z-Wave product manager Johan Pedersen presented the important improvements in the 700 series over the 500 series:

  • ARM M4 32-bit CPU
  • 150% RF range improvement in the US and more in EU/Asia
  • Lower power and faster wakeup time making coin cell operation a reality
  • Lower cost due to elimination of the external NVM & SAW
  • Single HW build for all regions due to elimination of the SAW filter
  • Longer battery life with 1.8-3.6V operation
  • Serial debugging

By far my main interest as a developer is that we finally have a real CPU with an M4 and serial debugging so I can finally single step my code and figure out where I went wrong!

The next natural question of course is when will the 700 series be a reality? The answer is “soon”. Ugh. Developers kits are supposed to be available soon and the parts will be shipping in early 2019.

Technical Track

On the second day of the summit the groups are split between marketing and technical geeks like me. More presentations on things like the new Z-Wave Plus V2 requirements which will go into effect with the 700 series release. The V2 requirements significantly ups the bar for support for various command classes with the goal of making Z-Wave devices to fully inform the hub of their capabilities. There should be little or no custom coding to support most V2 devices – the device will tell you everything it can do.

The presentation by Alex Capecelatro, founder of Josh.ai, described the future of voice control which sounds amazing. Alex described just how hard voice control really is and has a long way to go before it really works the way we all want it to. I liked his quote from the New York Times: “We overestimate what technology can do in 3 years but underestimate what can be done in 10 years”. Z-Wave has come a long way in the dozen years it’s been around.

Configuration Command Class

2018summitERI gave a presentation on Configuration Command Class Version 4 and all the wonderful things it can do. The most notable point is that 2/3rds of the Z-Wave Plus certified devices have at least one Configuration Parameter. Yet many hubs have no way of modifying or displaying to the user the current value of parameters. Z-Wave Plus V2 mandates support for Configuration Command Class V4 for both hubs and devices so you need to get busy! My presentation title is: “The Chicken vs Egg is over: Moving Your Product to Configuration Version 4” which can be downloaded from this link: Z-WaveAlliance2018EricRyherd.

Interoperables Band

Once again the band The Interoperables played at the evening get together at a local brewery. These guys are really good for having only practiced a couple of times!

Z-Wave Multi-sensor Version 2.0 with SmartStart – Batteries not Required

Merrimack, NH March 19, 2018 – Express Controls LLC announces the release of Version 2.0 of the EZMultiPli three-in-one multi-sensor and Z-Wave repeater. The Z-Wave Plus certified device is one of the first available SmartStart devices on the market and is available for purchase now on Amazon.

EZMFrontAnimFeatures

  • Motion Sensor
  • Temperature Sensor
  • Light Sensor
  • Color Indicator Night Light
  • Z-Wave® Range extender
  • Wall Powered – No Batteries, No wires
  • Screw tab for secure installation
  • SmartStart enabled

The new features for the 2.0 version are the addition of a screw tab for secure mounting and SmartStart. The tab on the enclosure enables secure mounting in either a standard outlet or a decorator outlet common with GFCI circuits used in kitchens and baths. The tab ensures children, elders, cleaners or maintenance personnel can’t easily remove the sensor. Secure mounting means the Z-Wave network is robust and reliable since EZMultiPli typically is a key repeater in the Z-Wave mesh network. Never worry about the batteries dying since EZMultiPli is wall powered. Installed by anyone with just a screwdriver – no wires, no batteries, no damage to the walls drilling holes.

SmartStart

qrPackSigma Designs SmartStart technology makes installation easy and secure. If your home automation system supports SmartStart, the first step is to scan the QR code on the back of EZMultiPli. If EZMultiPli was purchased as part of a kit containing several SmartStart devices, the QR code may have already been scanned at the factory. The next step is to simply plug EZMultiPli into a wall outlet and it will automatically join the Z-Wave network. Inclusion should begin within a couple of minutes but may take longer if several SmartStart devices are added at the same time. SmartStart uses the latest Security S2 encryption technology for all radio communication ensuring your system is secure.

CES 2018

The Consumer Electronics Show in Las Vegas is THE trade show for smart home technology and all things cool and new and geeky. It’s a massive show and I only spent one day there and never made it out of the Sands convention center which is one of the smaller venues. If you’ve never been to CES it is something to see. The crowds are enormous and the tech is brand new. So new, some of it will never actually make it to market as there is plenty of smoke and mirrors.

Eric Ryherd wireless IoT consultant expert

My purpose is obviously to seek out the latest news about Z-Wave and chat with my clients. The Z-Wave Alliance invited me to man the “Ask the Expert” desk at the show for a few hours which I was happy to do. My expert knowledge of Z-Wave answered simple questions like “what’s Z-Wave?” (It’s like wifi but low power) to complex questions about the rules around Security S2 and SmartStart.

The most common question is always what’s the difference between Z-Wave and Zigbee? My short answer is that Zigbee is like silos. If you can develop an app, gateway and all the devices you need, then Zigbee will work OK. Z-Wave however was a mesh network from day one and every Z-Wave device can talk to every other Z-Wave device regardless of the manufacturer. Z-Wave is built around standardized command classes so every hub knows precisely what format a temperature sensor is sending the data. Is it in celcius or Fahrenheit? Tenths of a degree or hundredths? With Z-Wave, the format is fully specified. The other protocols let you decide the format which is fine if you have the huge budget to do it all. But if your investors have you on a shoestring budget then Z-Wave is the way to go. I have much longer answers to the Z-Wave vs. Zigbee question but much too long to keep your interest in a quick blog post.

The big announcement for Sigma (other than the acquisition by Silicon Labs) is the announcement of the 700 series. Unfortunately details remain shrouded in secrecy but Sigma has put a stake in the ground of having developers kits by summer 2018. Finally having a real 32 bit ARM processor will be a huge productivity improvement for us IoT developers.

I had limited time to walk the floor but it does seem that smart home has finally taken off. There are so many companies making cool gizmos it’s overwhelming. From sun tracking solar powered umbrellas to cameras of every size and resolution to lots of new hubs there is no way one person can take it all in. You’ll just have to see for yourself.

The Z-Wave Alliance booth is even bigger this year filled with companies hawking the latest IoT thingamagiggy using Z-Wave. Every one of them able to talk to all the other Z-Wave doodads. The booth was busy all day long. I did wander past the tiny Zigbee booth buried in the back of the hotel with a few people in it but nothing like Z-Wave.

SiLabs acquires Z-Wave – Good or Bad?

On Friday of last week Silicon Labs signed an agreement to purchase Sigma Designs for $282M.

The question is: is this good for Z-Wave or bad? 

logoSilicon Labs is a well respected semiconductor manufacturer with an array of microcontroller products  from 8-bit 8051s thru modern low-power ARM CPUs. Silicon Labs has been chasing the IoT market since before IoT was a “thing”. Their low power micros have industry leading features often integrating the latest connectivity solutions like USB, Zigbee and now Z-Wave.  With a market cap of nearly $4B, Silicon Labs (SLAB) has a lot more financial muscle than Sigmas (SIGM) mere $265M could provide. All Z-Wave licensees should rejoice that a much larger company is now  supporting Z-Wave with the accompanying increase (we hope) of resources.

sigma-logoIn my opinion, the most interesting part of the announcement is that SiLabs is buying Z-Wave and not Sigmas primary business of Set-Top-Box processors. The announcement states: “Sigma Designs is in active discussions with prospective buyers to divest its Media Connectivity business”.  The announcement goes on to say that if Sigma can’t unload its “Media Connectivity business” then SiLabs will buy just the Z-Wave portfolio for $240M thus making the rest of Sigma worth only $42M assuming someone is willing to pay that much for it.

The Past

logo_zensyszwaveZ-Wave was originally invented by Zensys based in Copenhagen Denmark in 1999. Originally the Z-Wave protocol used Chipcon radios (acquired by TI) and Atmel processors (acquired by Microchip). In 2003 Zensys announced its own custom designed “100 series” Z-Wave transceiver which was a complete Z-Wave capable IoT System-On-Chip. In 2008 Zensys was struggling financially.  Fortunately Sigma stepped in an purchased Zensys for an “undisclosed amount”. Nine years later, Sigma has sold Z-Wave for a very nice ROI of perhaps 100X. Mergers and acquisitions in the semiconductor industry are frequent as technology and markets shift in unforeseen ways.

The Present

Z-Wave is growing like crazy as the number of 100% inter-operable mesh networked Z-Wave devices on the market continues to increase. There are now over 600 Z-Wave licensees with over 2100 products already on the market. With the recent addition of the AES-128 encrypted Security S2 communication and SmartStart to simplify the building of the Z-Wave network, Z-Wave shows it is continuing to evolve while still being completely backwards compatible with all the existing devices all the way back to the 100 series.

The Future

The future is nearly impossible to predict. I certainly don’t claim to have a clearer crystal ball than the next guy. But this acquisition bodes well for the future of Z-Wave. The additional resources should accelerate the introduction of the ARM Z-Wave microcontrollers which in turn will bring more Z-Wave products to market faster and cheaper. The soon to be announced next generation transceivers are expected to utilize modern ARM processors and make a significant leap forward in debug capabilities that are not present in the current 8051 8-bit CPUs. Z-Wave developers will finally be able to single step through their code instead of relying on printf to output a few cryptic characters giving you meager clues where your code has gone wonky.

Conclusion

The acquisition of the Z-Wave portfolio by a financially strong IoT silicon manufacturer is a “good thing” for the future of Z-Wave.

Biography

Z-Wave Expert Eric RyherdI went to RPI in the early 1980s where I honed my skills soldering and writing software. My first two jobs were designing graphics workstations and some of very first (and very primitive) GPUs of the day. I went on to designing chips for video conferencing compression engines, the cockpit display of the F22 fighter, Wireless Ethernet (before it was a standard) and a variety of chips for big and mostly small companies. Most of the chip designs were done as a contractor while I was also starting my first company, VAutomation which made “cores” for 8 and 16-bit CPU as well as USB and Ethernet interfaces. I sold VAutomation in 2001 and started playing with Z-Wave in 2003. I am the 31st Z-Wave licensee (there are now several hundred). At that time I went to work for a camera chip company that Cypress Semiconductor purchased and then I moved into working for Cypress. Since 2014 I have been building Z-Wave IoT devices before the Internet of Things (IoT) was a “thing”.
