Are you still trying to create dashboards without authorizing all or a single device? If you have tried even once to create a dashboard without authorizing, it can cause an issue. A reboot of the hub should fix it. Next release will fix this issue.
corollary to this issue. i just added a zwave motion sensor to the same room. along the way now the visionic door contact sensor is no longer updating and is now stuck in the closed state.
i have noticed this issue happen before when while discovering other new devices one of the existing devices will get stuck and no longer report updates. this is probably the 4th or 5th time that i have noticed this happen so not a one off.
It sounds like you’ve got interference on your zigbee channel. Have you checked for which wifi bands have the most traffic and set your zigbee channel manually to a lower use band? You may have had a neighbor change their router and start overlapping, or something.
still too many devices on ST. had to get the app ready for hubitat before moving everything over. now that that is done … one maybe two room migration each weekend starting in one corner of the house then moving across.
