I’ve just bought myself an MHI AC unit, after which I found out it’s currently hard to include in openhab.
People from HA have managed to control the device locally (see https://community.home-assistant.io/t/mitsubishi-wifi-module-wf-rac-smart-m-air/411025). Unfortunatelly I have no java programming skills. Is there anybody owing a MHI AC unit and java programming skills that already gave this a try?
Looks like this module makes AC settings accessible through http: https://github.com/jeatheak/Mitsubishi-WF-RAC-Integration/blob/main/custom_components/mitsubishi_wf_rac/wfrac/repository.py#L47 with some base64 encoded byte sequences: https://github.com/jeatheak/Mitsubishi-WF-RAC-Integration/blob/main/custom_components/mitsubishi_wf_rac/wfrac/rac_parser.py#L217C18-L217C18. AFAIR there was some discussion recently about MHI. Can you have a look or recent posts in Best Air Conditioner for OpenHAB integration in 2023?
This one was about the Intesis / Airconwithme WifiAdapters used in MHI units.
Completely different protocol used.
Can you post what model you have, for reference?
I have the SRK/SRC 50 ZS-WF
But from what I read most (all) units that have the WF-RAC wifi module should work using the posted method.
