Last week the power to our house was turned off for 5 minutes. When it came back and the raspberry pi restarted, HomeAssistant was saying that the Z-Stick Gen5 USB was unavailable as was also the Z-Wave switches. I restarted both HomeAssistant and Z-Wave a number of times but get the same result. However, the devices are actually working, the Z-Wave sensors report temperature and the Z-Wave switches switch as they are expected to.
What is going on here? Before the power off it was working all right except that the Z-Stick reported a humidity of over 500%.
