I cannot pair my T315 (EU) sensor to my H100 (UK) Smart Hub.

Tried resetting several times, both the sensor (pressing on side button for more than 5 seconds, to pair) and the smart hub (once, to synch).

I understand that it is not possible to pair a US hub/sensor with an EU hub/sensor, but mine should be okay, as EU and UK hub/sensors should be compatible.

Any help would be appreciated.

Thank you,
