Temperature Sensor auto-send not persisted

VelbusLink 9.84.0.0.

Changing Temperature Sensor - Advanced - Auto-send (from Never (default) to Every time it changes) is not persisted after closing and re-opening the project in VelbusLink 9.84.0.0.

Synchronize icon always remains green.

You are right, thank you for reporting. Should be fixed in the current online version (9.84.0.2).
(The sync icon will remain green, however, this is correct behaviour due to the fact that these are commands, not direct changes in the memory map of the module).

Could it be that this problem is back in version 10.8.5?

We’re looking into this.
