Some more testing with the Xiaomi Plug as a zigbee repeater in combination with an Orvibo door sensor.
Took the Orvibo out of the Hub’s range, its light didn’t light up.
Plugged a Xiaomi Plug next to it and tested if it was in range of the hub by turning it on and off.
Then tested the Orvibo by moving the magnet away. The light lit up and was shown in the app (+notification), so far so good.
Left it there for about 5 minutes with sensor closed.
After 5 minutes i moved the magnet, the sensors’ light lit up (message was sent) but no change in the app, still closed (and no notification).
It woke up after 4-5 tries.
Did the whole thing again with another Xiaomi Plug, same behavior.
I’m going to toss the Xiaomi Plugs and hub (sell them in NL). The Orvibo’s seem very reliable as long as they’re in the Hubs’ range. Unfortunately i still haven’t found any reliable Zigbee repeaters, so i might only use them in close range of the hub.
zwave has been really reliable so far.
I might give it one more try with using the zigbee-id, if i can get the Xiaomi Hub to work.
