Hi Johan,
please check the info in the Homey App Store:
So you need a Homematic CCU2, CCU3 or RaspberryMatic, more or less a DIY CCU.
A Homematic IP Access Point doesn’t work!!!
Since the Homey Homematic app hasn’t been updated for several years, I’d advise against using Homematic.
There is another Homey Homematic app available that has been slightly updated…
…but my requests have not been answered: GitHub · Where software is built
Athom had already asked eQ-3, the manufacturer of Homematic, whether they would be willing to program a Homey app, but as far as I know, this request was also not answered.
However, Athom would like to approach eQ-3 employees again at the IFA in Berlin.
Further information about the Homey Homematic app and the whole mess can be found in the corresponding app topic: [APP][Pro] Homematic App - Connect Homematic with Homey
