Heatline 24

Hi guys, fitted the extension and the bridge both are showing connected, but not showing in home devices, only in settings. I also fitted the wireless thermostat and that says unfinished installation. Been through it twice with 2 different types of boilers as I don’t have a room thermostat anyways and both times it said congratulations but still says unfinished and no devices show in home.

Any help would be appreciated.
