Yes, that’s my experience. As long as they’re connected directly to the hub i don’t have any issues.
But as soon as they’re repeated they seem to get into a sort of sleep-state after awhile. Then when i open them, the light turns on, but no message is sent to the hub (or received by the hub). The second time i open them, all is fine.
For me this is too unreliable. First i thought it was a problem with the Osram and was searching for another zigbee repeater. Then i got the Xiaomi outlets, same issue.
This happens only when they’re repeated. I have tested this with the Xiaomi outlets and an Osram outlet.
At first i only had the Osram outlet (all my others are zwave) and thought the Osram was the faulty repeater. Then the same thing happened with the Xiaomi outlets.
With the Xiaomi sensors, i don’t have this issue at all. They don’t drop off, the status gets sent through every single time. It seems like the Osram (as repeater) is working fine now too, but i have to do some more testing with that one.
So far, the Xiaomi’s, both outlets and sensors, have been very reliable.
