I think I tried gysmo38 module as well (in 2023) and didn't have any luck (different MQTT topics maybe?), so I just ended up using the SwiCago code per @michaelahess 's post.
I forked @interrobang's driver repo a while back and started adding features. I get the impression that he's busy with other things, so I had my fork added to HPM and will be doing releases through it. If you're interested, here are some features I've added to date:
- Supports
remoteTemperature, because internal heat pump sensors can be inaccurate (all of mine are) - Preference for
Gradual Temperature Adjustmentwith the goal of allowing variable speed heat pumps to run at lower capacity (I'd love real world confirmation of this) - Preference to
Adjust setpoint to avoid an immediate cycle when turned on, which just adjusts the initial setpoint by 2C for one minute
It's also worth noting that I've (mostly) switched the driver to working in half-Celsius increments (so you'll see temps like 67.1 if you speak Fahrenheit), which seems to be what the hardware/SwiCago do natively.
You should be able to find the driver and companion app by searching for "Mitsubishi Heat Pump" in HPM, and please drop any feedback or bugs here or on GitHub.

Yeah, you'll have to use the sketch I mention in the readme; gysmo's is for controlling via that little web interface it exposes!
