Glad that you are alright and that damage was limited. I am using mostly Z-Wave devices and so far I haven't had any issues, but I do also have some ZIgbee for temp and lighting, and so far so good,
But I see that the Xiaomi Aqara seem to be problematic deviecs (not sure you have those), but I assume they work well with the Xiaomi controller. Could it be a good idea to use the Xiaomi controller for Aqara devices and then connect Hubitat to that ? Similar to the Hue connection.
