I just checked and found out my Hubiat hub dropped connections with two of my Xiaomi devices:
- an Aqara leak sensor (paired February 24, dropped on March 19) and
- a original Door/Window sensor (paired February 24, dropped March 17)
My other 23 Xiaomi devices art still active and have been connected since February 24.
The dropped Door/Window sensor is the most distant device from my hub, so that could be the reason, but the leak sensor is only about 9-10ft (3 meters) from the hub.
As far as I'm concerned, if there's a way for me to receive a notification if a device's status goes to "INACTIVE" then I think I can accept a sensor's connection being dropped now and then, but not every day or every week.
@cuboy29 - Do you have any Zigbee repeating devices connected to your Hubitat? And how far away from the hub are those Temp/Humidity sensors?
I don't know of any good outdoor sensors, but since I've bought a bunch of the Xioami Temp/Humidity sensors quite cheaply from a couple people who didn't want them anymore, I plan to mount one outside in a place where it's relatively protected from direct exposure to sun / rain. If it stops working, no great loss. But I live in the Pacific Northwest, and we don't have real extremes in the weather, so hopefully it will do the trick.
