Hi,
I just switched from the Mitsubishi Melcloud app to their new Melcloud Home app. Then I realized I was using this in Home Assistant.
So the question is simple: is there an integration to Home Assistant or…should I stick with the old app (hoping I can set everything up again)?
It appears that Mitsubishi does not like these 3rd party integrations(seeing there is already a rate limit on their API). I would strongly suggest going for a local adapter.
Meanwhile I returned to the old app and everything is OK again.
Do you have good experience with a specific adapter?
This one. Does everything the cloud adapter do(except for cloud…) and then on the local network.
Thanks, will have a look at that !
Follow for any feedback on the original Melcloud Home question
Same situation here, but buy hardware doesn’t seems to be the best solution for me… also because is one for unit 
What do you mean?
There is currently no solution for a software integration with their new system so you would need to use a hardware controller if you want to locally integrate your heatpump.
Got a new Mitsubishi Electric MSZAP71VG installed last week and it came with a new WIFI adapter which only works with the new MELCloud Home app. Even the instructions in the paper manual were not fully updated to register the unit via this new system, the installers themselves were surprised by this.
It’s impossible to register with the old MELCloud one, so I’m stuck using the new app for now (which I’m finding to be buggy from being so new, not able to set schedules properly) and not being able to integrate it with Home Assistant.
Don’t know if it’s the new way with Mitsubishi to faze out the old app with newer units.
Really hope for a future integration with Home Assistant for this new setup, without having to spend more money to buy a LAN only WIFI adapter.
Open a support request via application in order to add new functionality. Maybe if they receive enough request they will do that 
I’ve opened one now, thanks for the suggestion:
Just use one of the opensource projects for air to water.
Integrating with the new melcloud home will not be that straightforward.
This one works really good together with HA and my new Mitsubishi Hero with Melcloud Home.
Not dependent on internet and it also works in parallell with Melcloud Home and its cloud access. Has MQTT and also a built in web server.
Costs a few bucks, but I think it is worth it.
the opensource options mentioned above does it all and more, and free.
for air to air, use GitHub - echavet/MitsubishiCN105ESPHome: ESPHome firmware inspired by GeoffDavis’s esphome-mitsubishiheatpump, directly integrating the SwiCago library within its codebase.
seriously there’s no reason to use a closed black box solution…
Protoart adapter worked really well for me as a beginner with Home Assistant and terrible at DIY, electronics etc. Used for a Mitsubishi AZY which would previously only pair with the (absolutely terrible) Melcloud Home app, which seemingly prevented HA integration. Now set up perfectly (I think) within HA via the Protoart adapter and MQTT integration. Would highly recommend
Hi, someone found a direct way into the Mitsubishi devices (local poll), and it just works (at least if your wifi “dongle” is the Mitsubishi MAC-577IF-2E )
maybe some refinement work still needed, but worth a try
Seems to working indeed but some units of mine have double entries where one doesn’t have entries but the other entity does. Do you have the same or know what it means? I’m using a multi split mxz-3f54vf4 with msz-ay indoor units.
Also should they be reset setup to wifi and not added to MELCloud Home or should they be added to MELcloud Home?
I hit the same problem as a few people here. I did my due dilligence, bought a new Mitsubishi A/C system, only to discover it doesn’t work with the core Home Assistant MELCloud integration!
I’ve now managed to reverse engineer the MELCloud Home web app API and have put together a HACS integration that talks to it.

It works with the newer MAC 597 integral WiFi adapter. One thing to watch out for is multi-split setups. The official app sometimes gives odd or missing energy numbers for those and HA can only show what the app provides. Everything else behaves as expected.
If you give it a try with your own model, let me know how it goes.
Hi Andrew,
great work. Thanks a lot.
I recently moved my two dualsplit A/C Systems to the new MELCloudHome Servers and can confirm that your integration also works with MAC-577IF-E and MAC-567IFB-E.
