Qubino app instability

Thanks for the suggestion, but what do you mean with “including very near Homey”? That one shouldn’t do that?
In the case of the shutter relays, Homey is about 3 to 5 meter from the relay. I noticed already that Homey shouldn’t be too far away, because apparently it needs to have direct contact with the device to be included and not via a mesh. But is there also a limit on how close it can be?
