    Are you the same DrZwave on Amazon?

    If you are, I read a review you posted on the LANMU battery power pack for the Arlo camera. You mentioned the power level reading 50%. Is that still the case or did it fail altogether?

      Yes I am. The battery power pack works great for the Arlo cameras. It always reads a battery level of 50% but it never runs out since its plugged into the wall.

    Hello, My team purchased the 500 series development kit and embedded development kit from Digikey ($2300 value combined) about 6 months ago and decided to go a different direction with our product rather than developing it ourselves. We’re looking to get some sort of value out it since everything is still pristine and largely unused. Do you know anyone that we might be able to sell it to for $500 for both?

      Unfortunately the 500 series kit is of much lower value now that the 700 series will be available in a few weeks. But I’ll post it here and see if someone wants it. Please contact @grayson directly if interested.

    Is the EZMultiPli still made or sold anywhere?

      Express Controls no longer makes it. Homeseer is investigating manufacturing the HSM200 version but they are currently out of stock.
