Support for Eurotronic TRV HostFlags

Encoding is the following for flags - default value is 1:

• 0x02 (2) = mirror_display - attribute TRVMirrorDisplay
• 0x04 (4) = boost - attribute TRVBoost
• 0x10 (16) = window_open - attribute TRVWindowOpen
• 0x80 (128) = child_protection - attribute TRVChildProtection

Decoding is automatic when receiving values but encoding is not implemented. Also you need to specify the Manuf code for Eurotronic 0x1037 when reading or writing manufacturer specific fields.
