Issue when adding 2 TRVs to 1 BT

[thorsten-gehrig]

Hi
I'm new to BetterThermostat (but: thanks work the work - it looks great!).
The first BT worked like a charm
The second BT should be for the living room - with 2 TRVs. As soon as i´m adding 2 TRVs im getting "Unavailable" in the resulting BT.
I have no idea where i need to look or what kind of logs in can provide - here are at least the device diagnostics:
config_entry-better_thermostat-01K6CXVDVEZ30GXF59QJ8WZGV5.json

I´m using this type:
TS0601_thermostat_3 => https://www.zigbee2mqtt.io/devices/TS0601_thermostat_3.html#tuya-ts0601_thermostat_3
HACS, HASS and HAOS are all on the latest available version.

I´m appreciate any hint or guidance.
Best
Thorsten

I´m just adding those thermostates seperatley to BT - and it seems one does show also allone "unavailable"... something seems wrong with this thermostate.
I´m investigating further...

Re-adding the 2nd thermostat to zigbee2mqtt did fix the issue - so it was not BT related.
Closing this.
