Fan mode has no effect on Flexa 2.0 board with Innobus

[marcodalli]

Hi all! First and foremost thank you @gpulido for you work: I finally managed to find some time to set everything up and with the latest updates it's working! I have an Airzone with Flexa 2.0 board, connected to HA via a RasPi with airzoneserial service; everything is working great, excpet for fan speed. I'm not sure if this a limitation of Flexa 2.0 board, but whatever speed I select, the AC will always go to medium when only one zone is active or high when two or more zone (the default behaviour). If I change the fan speed when the zone is active, the AC will stop completely.

Is this an expected behaviour / limitation when using Flexa 2.0? I remember reading somewhere that changing fan speed was not an option in Airzone, but I'm not sure... Moreover, speed change is supported from Daikin's control panel, so maybe there's a way to achieve this...

Hello @marcodalli, Sorry for the late reply, at this moment, the modbus integration that is being configured and used is the one from my old Innobus system and the more recent Aidoo. There was an issue raised in the integration library (python-airzone) regarding adding flexa 3.0 compatibility but as I did not have the hardware to test and the ¨rest api / localapi¨ new was also used I just didn't had time to finish it. The good news is that Flexa is very similar to Innobus, but they have some registers different (that is why some of the functionallity works, as airzone uses almost the same registers for the same functionallity). In order to check what is happeing with the Flexa 2, and even to try to take a look and adapt the code to make it work with it I would need the flexa 2.0 modbus integration protocol. Do you have it so I can take a look and know where we stand?

Thank you, Regards Gabriel

Hello Gabriel, unfortunately I don’t have such detail. If there’s a way to reverse engineer registers I’m available to do some tests with my board, if you can point me in the right direction.

Thank you,

Marco

HI @gpulido,
