Issues with Aqara FP300

(Certain) Ikea lights combined with Aqara devices on Homey, are a no go . Replace Aqara or replace Ikea lights / move the Ikea lights out of range of your Aqara sensors.

In short: once an Aqara sensor starts to use an Ikea router as hop, it stops sending updates, plus, it never searches for an other (more compatible) router again.
A temporary fix is to re-pair (without removing it prior) the Aqara sensor and restart the Aqara app.

It’s possible, but to me it’s kind of useless; a zigbee mesh organises itself. The sensor might not use the added router, or in case it does, it might stop using it next week and moves to an other router.
