Hi,
have the same problem. Homey often reports that it is offline.
If I hot the repeat button several times it gets reconnected but than loses connection after some time…that is specially very annoying if you are just editing or creating a flow and than it is gone.
It disconnects and reconnects every few seconds …
Here are some screenshots from insight about the power consumption
I have checked that zigbee and wifi aren’t using the same channel.
It looks like that with the android app I don’t have that often the problem.
