Just FYI, when you use a Homey Cloud instance, nothing is running on the bridge, it’s all in the cloud. The bridge is just a piece of ‘dumb’ hardware to provide an interface from a Homey Cloud instance to local radios like zigbee, z-wave, IR etc.
The current one…
Removeing the current one Homey (from the Homey mobile app)… removes everything… your Homey, the Homey with zones and the devices and flows. Everything…
Removing the Homey Bridge from your Homey inventory … just removes the bridge and reset it to factory defaults.
Then adding the bridge again to that same Homey will ask to connect your wifi.
