[APP][Pro] MELCloud & MELCloud Extension - Take control of your heat pump

Hi @OlivierZal,

Thanks for your swift reply and now I can see the correct value. Great tip.

Thanks again and have a nice day.

Hi @OlivierZal ,
I just learned that Mitsubishi (finally!) has launched a new app to control A/C devices. It seems to use a new platform called ā€œMEL cloud homeā€ and I have to delete all my A/C devices from MEL cloud and connect them with MEL cloud home. Can your app connect to the new MEL cloud home?

Hi @RainerMZ, unfortunately it’s not possible, as explained in [APP][Pro] MELCloud & MELCloud Extension - Take control of your heat pump - #385 by OlivierZal

Kind regards

Ou ffffff, it just reached me that potentially soon we will loose ability to control our Mitsubishi aircons due to switch to a new Mitsubishi app and APIs.

@OlivierZal do you think there is even a slightest chance to adopt this app in the future to a new APIs or it’s technically not possible due to some limitations? I saw post you linked before but still i dint understand is it a matter of time investment or technical reason?

I would really hate to see Mitsubishi goes away from homey. O_o

Hi @David_K,

Today it’s a technical limitation, but I’m not as pessimistic: not all the Wi-Fi adapters are compatible with the new APIs, so in my opinion – but I cannot be 100% sure – even if they push users to migrate to the new MELCloud app, they won’t deprecate the old APIs for now.

But indeed new devices won’t be accessible from the old app…

Hi, rumours reached me a while back as well… I decided to start looking for alternatives… (rather be save as my heatpump is completely steered through homey flows)
Here is what i found (it’s in Dutch https://gathering.tweakers.net/forum/list_messages/2240032?data[filter_topicstarter]=1 with links to github (in english))
Downside for straight forward implementation : you need to set up home-assistant and integrate it with homey (which is pretty easy) and do a small investment in buying an esp device.

All the rest is well explained and documented. I’m testing the approach now for about 2 weeks and it’s working for me. https://gathering.tweakers.net/forum/list_messages/2240032?data[filter_topicstarter]=1

I’m not a developer myself, but probably someone could create a similar homey app with all the documentation available…

Hopefully then only new Mitsubishi ACs will require new approach at least for the time being.

Fingers crossed as I really liked how I could automate start and stop of airco during hot summer days.

Thanks for the optimisim. :joy:

Hi,

Is it possible to add the possibility of a tag-option to the ā€œSet the modus toā€-card. I have a mulit-split airco system and I want to use a variable that registers the thermostat modus of the first airco unit that is powered on. When a second airco unit is powered on I can use the tag to switch the second airco to the right thermostat modus. As you know with a mulit-split system, when a second unit is powered on it has to have the same thermostat modus or else it will not function.

Is something like this possible?

Hi @OlivierZal ,

I have a question on the update frequency of the temperature values from the inbuilt temperature sensor in the indoor unit. I have noticed that there is a delay from when the value changes on Melcloud app to when it changes on Homey. I’d like to control the target temperatur in function of the actual temperature in some situations, and the slow updates are at hinder to a smooth functioning. Could this be fixed somehow?

Thanks!

Hi @PaoloF,

Initially the updates happened every 1 minute (or 3, for the air-water) but 2 years ago this frequency started to make the MELCloud API freeze during at least 30-120 minutes – on purpose, due by a new limitation set by Mitsubishi. After some tests, it occurred that 5 minutes was the minimum value letting the API work consistently.

Kind regards

I Understand, thanks for quick answer. Would it be possible to have more frequent updates just in some specific situations for a short period of time? Perhaps this would not hit the limitation set by Mitsubishi.

I have the new MelCloud Home app.
I’m wondering how I do this in Homey.
How do I do this?
I don’t understand all these messages. Can someone help me?

Hi @bartenke, unfortunately it’s impossible: [APP][Pro] MELCloud & MELCloud Extension - Take control of your heat pump - #385 by OlivierZal

Hi everyone,

It looks like there may be some room to extend the current app to support MELCloud Home.

To investigate further, I’d need people who have migrated to MELCloud Home and are willing to share access via a MELCloud Home invitation (available from the MELCloud Home settings). Feel free to ping me in a direct message if you’re interested.

Spoiler: based on what I’ve seen so far, there doesn’t appear to be any improvement in energy monitoring or features – MELCloud Home seems to be mainly a UI refresh.

I am willing to help but the aircos are my main heating unit so this needs to be working and automated, :wink: maybe in spring when I don’t need them daily :smiley:

Yes, my target is to have people who already migrated and don’t intend to roll back. But honestly I think the new app is worse than the other one – data is the same (including energy reports), no more zone handling, maybe just a better design but worse APIs so worse experience from my side.

I miss people with air-to-water devices who migrated.

Yeah I understand, but i believe Mitsubishi will develop the Home App in future and the old MELCloud will be deprecated. But this will take a couple of months to years :wink:

MELCloud Home improvements: maybe, but they weren’t able to improve the traditional app, so I don’t think they want invest in development for now…

Traditional API sunset: yes, rather years because not every Wi-Fi module is compatible with the new app.

Hi Olivier, I’m developing an android app to act as a standalone dashboard for Homey and I have a mitsubishi a/c (kirigamine series, with Melcloud) that works thanks to your app. I think I have managed to develop an interface, which you may be interested in, for better management of some capabilities of mitsubishi devices.

Attached some pic from my app, let me know if you are interested.
