Hi, thanks for your answer.
Yes read more in this topic and i found this maintainers mode so got the service menu and i could look to all settings… yes… its only the serial nr and unitname… nothing more… ohh i dint so the last link… i saw only an earlier version of the modul… but everything helps…

now i have a perl-script and i can manage the unit… now i need “only” a modul for fhem

Hi one question more…
do we alway read from Register 1 and write to register 4? Im implementing the “fireplace-options” and this ist 4times avalaible in write mode:

	Name	Endpoint	Number	Updated	changed	Value	Type	Flag	CCM ver.
	Fireplace Option	2	5895	13/02-2021 11:35:13	13/02-2021 11:35:13	0 / 00	BYTE	Writeable	2
—	—	—	—	—	—	—	—	—	—
	Fireplace Option	1	5895	13/02-2021 11:34:48	13/02-2021 11:34:48	0 / 00	BYTE	Writeable	2
	Fireplace Option	3	5895	13/02-2021 11:35:39	13/02-2021 11:35:39	0 / 00	BYTE	Writeable	2
	Fireplace Option	0	5895	13/02-2021 11:34:33	13/02-2021 11:34:33	0 / 00	BYTE	Writeable	2

Which register i should use? Writable are fields…

I found also a CookerHood Option, but is not available in the Controller, sombody played with this option?!

Name	Endpoint	Number	Updated	changed	Value	Type	Flag	CCM ver.
Cooker Hood Option	3	5428	13/02-2021 11:35:30	13/02-2021 11:35:30	False	BOOL	Writeable	2
—	—	—	—	—	—	—	—	—
Cookerhood Option	0	5428	13/02-2021 11:34:33	13/02-2021 11:34:33	0 / 00	BYTE	Writeable	2
Cooker Hood Option	1	5428	13/02-2021 11:34:45	13/02-2021 11:34:45	False	BOOL	Writeable	2
Cooker Hood Option	2	5428	13/02-2021 11:35:04	13/02-2021 11:35:04	False	BOOL	Writeable	2
Cooker Hood Status	1	5429	13/02-2021 12:01:10	13/02-2021 11:34:16	False	BOOL	Writeable	2
Cooker Hood Status	2	5429	13/02-2021 11:35:04	13/02-2021 11:35:04	False	BOOL	Writeable	2
Cooker Hood Status	3	5429	13/02-2021 11:35:30	13/02-2021 11:35:30	False	BOOL	Writeable	2

How i should set this …
I think its also a good think to use…

I activate the cooker hood option with 0x01, 0x06, 0x15, 0x34 and 0x01/on or 0x00/off… but nothing happend… only the "first 3 lines are now “true”

no hidden menu i can see in the controller to activate something more… strange is that the other 1 option and the status is not changing…

To be honest I couldn’t relate this to any information available in the sheet (and that’s all I’ve got). When in doubt, I just tried it and compared to the air dial to check if the update was successful.
Oh, and there are values that are not read from register 1, check this out for example:
