Maybe move this conversation to Github. It looks like your aircon has a lot more functionality available then mine does. The Mitsubishi-echonet library was coded in such a way to allow new functions to be easily added in when people needed them. What you want to look at is the ‘set_properties’ under the property_maps (which I cant really see above) this is what you can actually tell your HVAC what to do or ask for. I’m afraid however you are going to have do a lot of trial and error, but feel free to fork the library and read the Echonet specs, and play around with it.
Seems like I missed a lot on this thread, it’s been over a year since an update broke the integration that I had for my Mitsubishi system.
See this library I wrote (which was done by reverse-engineering the communication with the java applet): https://pypi.org/project/mitsPy/
If anyone wants to collaborate with me to get it working again, I’ve since done some more reverse engineering and would love to work on it as a community project. I don’t have the time to do the whole thing though.
My system is a Mitsubishi GB-50A central controller, though I’ve heard that many newer controllers still have the java applet compatibility, which can be used to create a more generalized home assistant integration for Mitsubishi controllers.
This is brilliant. I wanted to add a Wemos D1 to our system but as “we already have WiFi control!” the objections became so loud I gave up…until now. Working nicely, thanks!
@scotty I just wanted to say thanks for your integration. I couldn’t get my Mitsubishi Electric AC working with Melcloud/Melview for some reason (won’t accept password) and your integration worked

I have it working now (for the most part) with some ceiling cassettes - Models SLZ-KF25VA3, SLZ-KF35VA3, and SLZ-KF50VA3. The fan modes work, but not all of them do anything - so I might need to trim them back…as far as I can tell I only have Auto + Low, Medium, High but these don’t translate directly to the fan_mode names so I will need to do a little testing to get the right ones…not that it matters…mostly we’re on Auto anyway… Thanks for the excellent work! Now I’m going to play with the sensor config as I don’t need each unit to report the outside temperature… 
Firstly thanks for all the great work that’s been done. I’ve really only just started my journey with HA.
I was hoping to add some smarts to my Mitsubishi ducted air con, without dumping a tonne of cash into one of the integrated smart solutions.
I’ve so far integrated some reflashed Xiaomi sensors and I was hoping I’d be able to setup some rules and then use an integration to be able to control zones (even just non/off). The echolite is great but limited for me with multiple zones.
Did anyone get this working at all? I’ve had a look around GitHub but didn’t see any working implementation for zone control.
I am using my mitibushi ducted with external Xiaomi sensors flashed with GitHub - pvvx/ATC_MiThermometer: Custom firmware for the Xiaomi Thermometers and Telink Flasher via USB to Serial converter but any sensor in Homeassistant should work. but I am using esp home with this GitHub - geoffdavis/esphome-mitsubishiheatpump: ESPHome Climate Component for Mitsubishi Heatpumps using direct serial connection works great.
Does it have zone support?
@scotty GitHub - scottyphillips/mitsubishi_hass: A Home Assistant custom component for use with ECHONET enabled Mi is unreal. Early days but it seems to work an absolute treat with my MSZ-AP60VGKD that comes with a MAC-568IFB2-E wifi adaptor. Great install guide too. Just what I was after. Thank you very much. Justin, NZ.

I tried installing tonight for my mitsubishi aircon and it works fine
(homeassistant on docker with linux)
thankyou very much for your great effort writing this.
I will explore the options for fan speed once I get my head around the project. 
that is the very reason I wanted to do this installation as I dont want to be tied to mitshubishi’s cloud based product. No need for it!
There is an improved version on the way.
Hi @scotty
I am using your HACS plugin and after an update to HA 2021.9 everything seem to broke. In logs I can see constant warning
WARNING (MainThread) [custom_components.mitsubishi.climate] HA requested an update from HVAC XXXXX but no data was received
And seems like AC entities have duplicated but nothing seems to be working. Any thoughts how I can fix it?
The ECHONETLite repo has been substantially updated and is in the process of being republished to HACS
It is no longer specific to Mitsubishi systems with the MAC-568IF-E WiFi Adaptor, it should in theory be able to support ANY Echonetlite device.
You will want to delete the old component and use the updated integration. It’s much nicer and has A LOT more features.
Can you confirm that it will work with most any of the MSZ-AP XXXX systems?
I’m looking at the MSZ-AP71VG(D*) and it’s not specifically mentioned, although the MSZ-AP50VGD and others are.
As long as the Wi-Fi adaptor is the MAC-568IF series.
Thanks Scott!!
I have the MAC-559IF-E, I have the power and temperature control working but not the zones, has anyone got zones to work or do I need the spend $200 on a new wifi module?
