We’ve been using Z-wave here in the new house for several months. The hardware is still glitchy. It does not have high enough nines to be super dependable.
Just today, the Aeotec Zstick S2 got “stuck” for lack of a better description. The blue light was stuck on, but it would not respond to software commands. The Zstick has a built in battery, so you can’t just unplug it to perform a reset. After some trial and error I found there is a small pinhole size button on the bottom of the stick. I commenced pushing this virtual red button hoping that it was not a factory reset button. This little button did the trick, all is working again until I have to repeat this process.
