It’s always difficult to pinpoint what is going wrong in this kind of situations. This is not normal behavior.
Some other thoughts:
- The Zigbee mesh network should be self-healing, though this can take some time (hours) and requires that devices are active. What might help if you power down Homey for 15 mins, power it back on and let it sit for a while. In the meantime activate your temperature sensors by pressing its button. This will also activate its Zigbee antenna and make it try to connect to the Zigbee network. That might reroute its connection.
- If you choose to remove the sensors (which will impact all flows that are based on them) there is this script available that replaces the old with new device IDs in flows after removing/re-pairing the device: [HOW-TO][Pro][Cloud] - Tool to FIX (advanced) flows after removing and re-adding devices flows after removing and re-adding devices. I don’t personally have experience with it, but I see that other community members have and were able to fix their flows.
- You could reach out to Athom for support, via Support | Homey . Maybe they can see what it going wrong ‘under the hood’.
