Support for Flower Care Max sensor?

[mkaut]

Is the new Flower Care Max variant (for ex. here supported?

I bought one, connected it to the app and then wanted to add it to the daemon.
I found its MAC using hcitool and added it to the config file, but it never became online...

And when I checked the sensor the following day in the app, the app could not connect to it either - at the end I removed it from the app and tried to repair. The app finds the sensor, but never manages to pair.
Is there any chance that the deamon could have caused it? Or was I just unlucky with the piece I got?
