In my OpenHAB I’m using the ComfoAir Binding to manage a ComfoAir 350. Controlling the fan, switching between app and cceayse and other items are working well but I have some Issues with this Items:
Did anyone see the bypass switching?
Hi everybody
today I have finally connected my ComfoAir 350 with openhab and I was facing the same problem:
all device commands are throwing warnings after updated the first time, besides “activate” and the four temperature commands.
Filter commands also throw ArrayIndexOutOfBoundExceptions.
Any solutions?
Cheers
Sepp
Hmm, not good… I bought a ComfoAir 350 on the premise it would work with OH 
It is working well.
At the moment just the display of the bypass is not working. But you I plan to fix that issue when I know that it is not working for others, too. I don’t know if other models are working with that command.
Haven’t finished the house, hence, also not yet installed the 350…
@Sebian: I seem to remember, that the reading of the bypass Status worked for me last summer. As I changed my persistance with OH2 in autumn I don’t have data of this anymore and at present it’s too cold outside (at least in Germany! ) for the bypass to open. So I can’t check at present.
What I occasionally get is the following WARNings:
2017-03-20 10:44:21.582 [WARN ] [.comfoair.handling.ComfoAirConnector] - Unable to handle data. Data size not valid

but this doesn’t seem to be connected with your issue, does it?
@Sepp: the binding itself works perfectly, if you don’t Count the occasional WARNings described above. So if your Installation throws ERRORs like you described, you could start a new thread with your configuration and we can have a look at it.
So, as it was just about time to change my filters anyways, I did some research, and as it appears, I’m missing:
{comfoair="bypass_mode"}){comfoair="filter_error_extern"}){comfoair="error_message"})at least those three don’t show up in the events.log,
all others do:
{comfoair="activate"}){comfoair="fan_level"}){comfoair="target_temperatur"}){comfoair="outdoor_incomming_temperatur"}){comfoair="outdoor_outgoing_temperatur"}){comfoair="indoor_incomming_temperatur"}){comfoair="indoor_outgoing_temperatur"}){comfoair="incomming_fan"}){comfoair="outgoing_fan"}){comfoair="filter_running"}){comfoair="filter_error_intern"}){comfoair="filter_error_extern"})I also found out, not all commands from the protocol description are available in the binding. What I miss most, is the “filter reset”, so i opened a new thread:
Thanks a lot, I found that I did a mistake, after reading your replies. I was of the opinion that it is possible to control the bypass, therefore I was using a switch for it. After a look into the items definition a saw that it is a Number which is mapped by a mapping. After using a Dummy instead of a switch everything works well.
Thank you for creating a new Thread for the reset filter functionality, that will make it easier to reset it. Each time I replaced the filter, I was looking into the documentation to find out how to reset this.
