I have just installed 12 Xiaomi door Window Sensor Intelligent Mini Door Sensor Pocket Size.
I’m using these inside my crank style windows. They are really small! Small enough to fit in the casing which is great!
On one hub, I have a lot of Zigbee devices, all battery operated except my Sinopé TH1123ZB and TH1124ZB thermostats and one IKEA Zigbee extender. Half of my sensors are on that hub. On the other, the remaining 6 sensors are the only Zigbee devices. On that last hub, the devices have been connected for a good 7 hours now with no issues.
On the hub with other Zigbee devices, they keep getting disconnected. I suspect it is because of the thermostats, but am not sure how I can confirm this...
I can easily just resolve this by moving all my devices to the hub that works, but I’m thinking that there might be value in debugging this. Unfortunately, I have no Zigbee stick - I can only work with what Hubitat gives me. Does anyone have a recommendations on where to start?
@markus, I have switched to your driver (v0.7.1.0701). I really like the extra functionality that it has! Hoping that we can find out what is causing the issue on the one problematic hub!
