Any update on getting to the root cause and fix to stop Hub from not responding? This weekend I was away and had HSM activated. When we came home last night first clue something was wrong was our entry door did not automatically unlock. Then when we entered the motion detectors did not turn on lights like they are supposed followed by no notification from Alexa that alarm had been activated and needed to be deactivated before siren goes off. When I attempted to check the hub I hit the same situation as others where I got no response. I unplugged hub and when it restarted lights then came on and HSM sent appropriate a alert to Alexa and my phone that alarm had been activated and siren would activate in 20 seconds unless disarmed. I find I have to restart my hub about every 10 days as this freeze issue keeps occurring. I will try implementing the community hub rebooter app but that really does not solve the problem if hub freezes in the middle of the day and HSM is Activate I would have no way of knowing if someone broke into my house or not. I hope the good folks at Hubitat will be able to fix this freeze issue within the hub itself.
