So ZHA has decided to flip the table and just not work. Out of 49 devices i have 3 sensors working (great!). In the logs I can find this:

Nothing I’ve found really seams to fit my situation. I have a Conbee (I/1) and people seems to be pointing at interference. It just seems a little odd that all the mains powered devices would out-interfered but some battery powered devices (not close by) are not.
The whole situation feels odd and I can’t say for certain but it feels like this started (or at least started getting worse and then ending in this catastrophe) when/after upgradeing to Home Assistant Core 2025.4.3
Other versions are:
- Supervisor 2025.04.0
- Operating System 15.2
