@rvdbreemer, can you please try again?
Fantastic, this works! I am going to start working on this! THANK YOU
Hi! I’ve been trying to add my air to air heat pump, but there’s a constant “no devices found”-error shown. See image (error message in Norwegian). Anyone know how to fix this? I’ve tried changing the password in the MELCloud app, but that doesnt help.
Hi,
just new in Homey … just receive some days ago my Homey Pro.
I have multiple Mitsubishi internals units and with the add the your application it discovers all of it.
I could create some flow to stop/start my units, make them as Favorite Flow, then link them to Siri on my Iphone. So I can run a flow manually on my Iphone and also by asking Siri to execute a flow.
My question is in a flow:
- how can it set with a flow the temperature i want ?
- how to to it to heater, cooler mode ?
P.S. great apps @OlivierZal
Thanks a lot.
Hi, sorry @OlivierZal
just found the card for setting the temperature.
But is there a way to call a flow (and via siri) where we call a flow and specify “dynamically” the temperature we want ? or Ask increase by 1 and decrease by 1 the temperature ?
thanks
Hi @Eric_Franckx,
I don’t know if it’s the best way, but you can define a flow “+1” and a flow “-1” whose trigger would be a “Homey button” (available from “Homey settings > Experimental”).
With the HomeKitty app you sync the 2 trigger buttons with Apple Home.
Then you are able to launch the corresponding flows from Apple Home, either by clicking on the buttons or call them through Siri.
I hope it helps you.
Kind regards!
hi thanks for fast reply.
Just i don’t fully understand how to achieve the flow +1 and -1 and allow to decrease/increase the actual temperature of an airco unit.
regards,
Eric
@OlivierZal but your is very cool. Thanks !!!
Example for +1:
First, you need to create a “intermediate_temperature” variable under Settings > Logic
- Trigger (when): button [name] is activated
- Action 1 (logic - calculate): intermediate_temperature = {{ target_temperature(of your device) + 1 }}
- Action 2 (MELCloud - your device): set target_temperature to intermediate_temperature
I struggle with a few cases where a flow has failed lowering temperature on my Mitsubishi Kaiteki at night. I guess MelCloud sometimes just won’t respond? Is there a way to “catch”/log this and maybe retry it later?
Maybe use the error function of the card?

Trigger det function again, log in in timeline, wait a minute and read the temperature then trigger the “set temperature” car again, and so on.
I’m currently getting 401 errors when I try to set any setting via the device in Homey. Restarted the app, Homey and even power cycled the heat pump. Anyone else having issues?
I had to re-enter my credentials in the app configuration, I guess it makes sense given the 401 error
Hi @Articate, it’s a MELCloud global issue, see [App][Pro] MELCloud - #63 by OlivierZal
Kind regards
Thank you very much for the app. I have a minor issue when using change of actual fan speed as trigger. I am trying to use it to detect de-icing of the outdoor unit.
I have configured a simple flow who starts and writers the fan speed to the timeline, but it never triggers. The change in fan speed is logged in insights and reported correctly when the flow is started manually. Maybe some delay from Melcloud?
Kind regards,
Mathias
Hi @Fiffus, can you screenshot the workflow you configured, so I can understand better?
Fan speed and actual fan speed are not synced, and there’s a delay between both, on which the end user has no control since it’s controlled directly by the heat pump system.
@Fiffus, I’ve found the bug, will fix it in the next release.
Hi. Hello. Good. Thank you. The screenshot is in Norwegian. I just use “actual fanspeed”.
I think use of this trigger to count number of de-icing cycles can be quite useful to power on another heat source after x cycles to prevent ice building up.
This will never trigger. But works when manually started:
What do you actually mean/What is the idea you have? It is already a heating cable in the bottom of the outside housing.
Yes. But depending on placement, the water from the outdoor unit can result in a lot of ice over time if it freezes under the unit. I have a additional heat source that make the water drain to a level with no frost. There are a lot of different products made for that purposes. And even if it the wattage just are about 150w There are no reason to leave them powered on most of the wintertime. 15 min when the heat pump de iceing does the trick.
