MELCloud integration: PaC not supported. Add it?

[StephaneB]

Hello @pierre-gilles.
My new Mitsubishi heat pump (PaC) has just been installed. Of course, I’m planning to control it with Gladys via the MEL Cloud integration
The heat pump is correctly connected to my MEL Cloud account, and the Gladys integration with MEL Cloud is properly set up. But Gladys tells me that this heat pump model (PUZ-WZ60VAA) is not supported.

I imagine that it’s necessary to add certain elements in the Gladys integration for it to be recognized… Is that possible? Do you need any elements that I should provide you?

Hi @StephaneB,

Thanks for your message and for the details provided

After checking, your model PUZ-WZ60VAA appears to be an Air-to-Water heat pump, whereas the current integration in Gladys only supports Air-to-Air models, which explains the behavior you’re seeing (see screenshot below).

I’m not the original developer of the MEL Cloud integration in Gladys — it was done by @Lokkye, who unfortunately hasn’t been active on the project for some time

@Lokkye I saw you logged into the forum recently; if you have a bit of time and would be willing to shed some light or lend a hand on this integration, that would be really great Of course, no obligation.

Thanks for the explanation, @pierre-gilles. And I confirm that it is indeed an air-to-water heat pump (PaC).

FYI, a quick search sent me to this page that describes the differences in ‹ readable state › and ‹ writable properties › between the two types of heat pumps (PaC): Client Challenge

@Lokkye thanks in advance for whatever you can do, if you accept And if

Well, I integrated this heat pump (PaC) via Node-red and the node-red-contrib-melcloud-atw module. It works well and it allowed me to understand which states and properties were useful. If someone starts development to enrich the MELCloud integration in Gladys, I can help…

I have also owned for 4 years a Mitsubishi ECODAN silence heat pump (air-to-water) that I connected to Gladys

via Node-RED and MELCloud, but I only retrieve the heat pump’s variables; I have never managed

to send values (setpoint) to the heat pump.

I am also interested in an integration into Gladys, but I am not a developer!!

[StephaneB]

When writing, I can configure two things: the temperature setpoint and the on/off of the heat pump (PaC).

Voilà ce que j’ai défini :

The buildingid and deviceid should be extracted from the payload you obtain when retrieving the heat pump (PaC) variables.
