Please keep watching the changelog for Release Candidate versions, there might be soon new comming in, as Athom just released “stable”.
I strongly believe this is a power management issue and that the ble power was reduced in 13.4.x update. Hence, the communication range decreased drastically.
I have moved sensors and homey closer, and have improved connection stability now. However, the sensors are not where I want them now, wrong room, so really not a solution for me, only a test.
