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.
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.
