YW, Ken.

Adding a few routers (mains powered zigbee devices) around the flaky sensors can’t hurt.

Zigbee 3.0 is _a_ standard, but some (particular devices of) brands just don’t mix @ Homey, like, Ikea lights and Aqara sensors.  
When an Aqara sensor starts to use an Ikea light as router, it stops sending updates AND it never looks for an alternative router again.  
The interview, or re-adding the device solves it, until it, again, starts to use such Ikea light.  
Unfortunately there’s no setting to “blacklist” certain routers for certain sensors, neither does it blacklist incompatible routers itself.

Checking & adjusting the 2.4GHz wifi & zigbee channel might help as well

The “24h limit” is also challenging me; Maybe there’s a nearby device running in daily cycles, causing temporary interference. Think of Bluetooth devices, microwave ovens
