Currently the Comfo Connect KNX module hast only very limited access to data sind commands. The LAN module and the App ist much more powerfull. Currently the KNX module is not worth buying but IT.
The 3dparty Module comfoway ist much more powerfull but also much more expensive. But currently the only real option if you need a good KNX Interface to Zehnder Comfoair Q350. I would prefer buying the Zehnder Module but not with its current limitations
