Fibaro Smart Implant sending strange values

I’ve the same problem. Did connect 2 external temperature sensors to the fibaro smart implant. Had first to exclude from Homey and then reconnect again so the Fibaro will recognise the new sensors.
For about 2 hours Homey reports the correct temperatures.
After that reporting freezes and the last reported temperatures are not changing any more.
The Fibaro INT1 and INT2 are still working correctly and are reporting the correct state.

I think it’s a Fibaro app bug.
