[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.
