Mitsubishi MELCLOUD integration with Home Assistant

Andrea.adi · April 20, 2020, 8:27pm

Hi, how do you add it on HomeKit?
Thanks

Andrea.adi · April 20, 2020, 8:48pm

Done, thx!!

Hi guys!
I need support… I successfully configured the integration via HA settings but I see this message:

Why? No devices are discovered even if I can see them in the Mecloud APP.

Trying with o0Zz’s solution everything is ok!

Are you using the version bundled with home-assistant? What version of home-assistant are you running?

0.108 should fix an issue with detecting devices assigned to areas within a building. The release notes are not that accurate with these smaller profile integrations making latest stable the safest bet.

If you are running the latest stable release of home-assistant, how have you assigned your devices to areas/floors/buildings/etc?

Gabriele_Mandalari · April 24, 2020, 11:56pm

I’m running HA 0.108.5 and this is my melcloud config:

You have the patched device search. That’s not the issue then. I’ll test a similar setup anyways later just to make sure.

What devices are these? Could you send me a ListDevices response capture from MELCloud as a private message?

vilppuvuorinen · April 25, 2020, 7:00pm

I just realized that I had PR’d the device search patch to incorrect branch. It’s coming in 0.109 that should be released on Wednesday.

If you want to get things working before 0.109, ‘Move’ the devices to ‘No Floors’ and ‘No Areas’ in MELCloud. You can find the option under ‘Actions’ -> ‘Move’ of the devices.

What is the consequence of this sentence " While not optimal, the provided password is not stored ." ?

Does it mean that one has to type password at every homeassistant boot, or ?

vilppuvuorinen · April 29, 2020, 6:56am

No, it doesn’t. The password is exchanged for a token and the token is stored. I acknowledge the possible issues caused by token expiration, but this far no one has reported about an expiration nor have I personally witnessed one. If issues come up, another solution will be selected.

Cool, thanks.

I’m in the process of clean-up of my yaml-files, after been running on lovelace for sometime. I rather use the front-end for all I can.

Hello @vilppuvuorinen and thanks for the integration of this component in HA. However, I’m having the same issue as @snowatom (Running HA 0.109.6). Already tried to pull out of zones one of my devices, as per screenshot, but no luck scr

o0Zz’s custom component solution works

stevevg · May 13, 2020, 11:04am

Retried today (with no modifications).Works

vilppuvuorinen · May 14, 2020, 7:31pm

@stevevg Great! Is it working for you even when devices are assigned to areas?

stevevg · May 14, 2020, 7:53pm

Yes, my devices are divided between zones

vilppuvuorinen · May 16, 2020, 10:42am

This is a sort of a request for comments: I’ve added preliminary operation mode support for Ecodan device zones to the hass-melcloud experimental repo. A separate climate is added for the flow heat/cool modes. These climate entities reflect the current operation mode selection using simple hvac modes. When flow heat climate is in heat mode, the system is in flow heat mode and other climate entities related to that zone are in off hvac mode.

I’d appreciate it if anyone has the time to test this feature out and comment on the approach.

Hi, i have two vertical fans. Is it possible to control them separately in HA?

vilppuvuorinen · May 23, 2020, 7:05am

@Johnyyy I don’t think that is possible. If you can control it from MELCloud, it should be possible. Please let me know if you have figured out how to control this through MELCloud.

Johnyyy · May 23, 2020, 4:47pm

Hi,

I can control it from the melcloud app. My heat pump is LN35.
The problem is, when i use Schedule in melcloud app, it’s not possible to use two different vertical settings.

I want full speed when i am at woork and slow speed when i am home. So i can’t use the schedule function. Whould me great if it could work with HA.

vilppuvuorinen · May 24, 2020, 4:07pm

@Johnyyy Interesting. How exactly can you do that? I would need some screenshots of the controls in MELCloud. If you know your way around developer tools, could you also capture the HTTP requests associated with setting the fan speed? It’s the SetAta request. It contains a bunch of semi-awkward info tho. You should try to check you aren’t leaking too much info and share it over a direct message.

Hi! I’ve problems installing the new Melcloud integration, after setting the username and token on the UI, hassio return the error “Error handling request”. I have to say that I previously had the o0Zz custom component installed, and that before trying to add the new integration, I have removed its custom component folder and its configuration from configuration.yaml. Can anybody help me please?
Here the traceback:
