Excellent video! Great technical content. I don’t agree with his concern about Z-wave devices being supported in the future. For one thing Sigma Designs no longer exists. They were acquired by Silicon Labs who knows how to grow protocols. There are so many Z-Wave devices in the field and so many large companies that depend on them, the entire home security industry for example. They even announced that Z-Wave is opening up to allowing other companies to produce the chips. But I do like this video.
