I have a strange zigbee problem since few weeks in my home.
Most of my devices were zwave until few weeks ago and I never got any problem with them… I mostly have Stelpro Ki thermostats running on zwave and few leviton switches, zwave too.
The only zigbee devices I had was those coming from the starter kit and few water leak detector I bought.
Everything was working fine… yet.
Few of my collegues were successfully using cheap Xaomi Zigbee devices from AliExpress, so I decided to start using them too. I bought few Xaomi sensors and Heimantech Smoke detector (I even published a handler for them). At the same time I was needing to replace 2 thermostats, so I decided to buy the Zigbee version of the Stelpro Ki to help improve the Zigbee mesh network for my new sensors.
I installed everything… and it works correctly. At the exception the devices started disconnecting after few hours/days. None of my new sensors were acting correctly. I was pretty annoying.
I suspected it was a problem with the Zigbee mesh, so I decided to “repair” the mesh network. I read the best way to do it is to shutdown the hub for few minutes. I did that and… I lost most of my zigbee sensors even those which was working correctly before.
After a lot of investigations, I decided to turn off the zigbee feature on my 2 “zigbee” Stelpro Ki and… after few minutes all my Zigbee devices connected successfully to the hub!!
So… it seems there’s a problem with the Zigbee edition of the Stelpro Ki when they are acting as repeaters in the mesh network… Anybody knows how to fix that??
Problem is fixed by adding more powered zigbee devices acting as repeaters.
I bought few
ECOSMART Connected LED Light Bulbfrom Home Depot and
ZLL xxx Bulbhandler and the problem is now solved.
There is absolutely no problem with
Stelpro Kidevices: they are working great!
