Hello everyone,
I have several Mitsubishi Heavy air conditioners with WF-RAC adapters integrated into Home Assistant via the
GitHub - jeatheak/Mitsubishi-WF-RAC-Integration: WF-RAC homeassistant integration integration. It’s actually a great solution, and the author and contributors did an excellent job. The only issue is that it doesn’t have the Self Cleaning operation. The problem is that even the official Smart M-Air app doesn’t have it either. Only the original physical IR remote has it. I found another great solution with the
GitHub - absalom-muc/MHI-AC-Ctrl: Reads and writes data (e.g. power, mode, fan status etc.) from/to a Mitsubishi Heavy Industries (MHI) air conditioner (AC) via SPI controlled by MQTT integration, but unfortunately, this operation is also missing there.
This is actually a pretty important mode that helps reduce mold growth, which was one of the reasons I chose these MHI units. I believe there are a lot of MHI owners here who have integrated their units into HA and use the Self Cleaning mode.
So, my question is: has anyone managed to find a way to activate this mode via HA?
This mode can only be activated using the original IR remote: after pressing the Off button, the Self Cleaning mode starts. The remote displays the duration of the cleaning process. In the integration or the official app, this just appears as the fan running.
From what I understand, the only way to integrate this mode into HA is through some universal Zigbee IR remote that can read signals from the original AC remote and send the correct command to enable Self Cleaning.
I have a Tuya IR remote, but unfortunately, it doesn’t support signals from the original AC remote.
If anyone has experience with this and can share which IR remotes work with MHI and Self Clean operation, I would really appreciate it. I have an SRK25ZSX-W.
