Heat pump

Hello,

I’m considering installing a ducted heat pump at my home (early 2025) and am looking into prices (not the subject here) and the system’s external connectivity (the subject)…

I’m being offered:

  • MITSUBISHI ducted heat pump PEAD-SM71JA / SUZ-SM71VA
  • AIRZONE plenum(s)
  • Airzone webserver (seems mandatory but also works locally in case of an « internet outage » according to the site’s FAQ…) + Wired BLUEFACE thermostat + 3 or 4 THINK White wireless thermostats

So I went looking in the documentation for how to communicate with the heat pump and also with the Airzone system (which controls the plenum dampers)… And I can’t find anything…
Since I don’t know much about Gladys (I’m getting started) and not much about ducted heat pumps… it’s not obvious what needs to be done/chosen to allow the heat pump to be autonomous but also to monitor and control it remotely :wink:

Has anyone among you been able to connect a Mitsubishi to Gladys? this type of model? a plenum with motorized damper? of the Airzone brand?
From your experience, is there a brand to recommend over others? or one to blacklist?

PS: the goal is to be able to take advantage of the developments on this topic: Avoir des appareils adaptés au chauffage and the other possibilities that Gladys enables or will enable :wink:

Hi @Gnome :slight_smile:

You’re in luck — we’ve been managing Mitsubishi ACs via MelCloud since August 2023!

However, you need to have an AC that’s compatible with MelCloud

Hello

I need to look into this because

So for those who are looking (like me), here’s the link to the documentation that provides the listing of compatible models (do check, though, that the Wi-Fi module is actually supplied):
https://www.mitsubishi-les.com/assets/documents/39680/1/im-om-controls-melcloud-en.pdf
link to the various MELCLOUD documents

Mine, PEAD-SM71JA, is indeed listed, so if it does have the Wi-Fi module, no worries for Gladys…
However, the one upstairs (the same but with a controlled plenum) I need to continue my research… if I go ahead with that one lol

I was able to make some progress on the subject… For the MITSUBISHI heat pump no problem (if it has the Wi‑Fi module), but for the Airzone plenum I found nothing (directly without their Cloud)…
I’ll therefore look for another motorized plenum…

EDIT: if people have plenums at home, I’m interested in the brands and models if they can be connected to Gladys…

EDIT 2: indeed, it’s when I think I’ve covered everything that I come across other things…

Apparently on Jeedom they succeeded… maybe with the Cloud, I find it hard to understand… I’ll continue my reading and research

EDIT 3: https://developers.airzonecloud.com/

I’m following this topic closely because I’m going to install AC at my place :slight_smile:

I have a first appointment this Friday with an installer, I’m going to push for Mitsubishi with Melcloud

Hello @Dream_Gladys, is it possible to manage Cozytouch? Thanks in advance

Hello @thierry06

I have no idea at the moment — I don’t really use Gladys because I don’t have the time and I’m having trouble understanding everything :sweat:

@thierry06 apparently CozyTouch has a Node-RED module: Read data from Cozytouch (thermor) API (flow) - Node-RED

So it can be used by connecting Gladys to Node-RED via our integration!

So it would also work for a remote Cozytouch-enabled home, excellent! I’m adding Node-RED to my 2025 resolutions ;_)

Ah!! Interesting for Cozytouch!! I have it too and I was planning to look into it when I can get back to development…^^

As for the heat pump (PAC) I’m on a Midea ^^ I’ll take a look!!

To keep you posted, air conditioning installed this week :slight_smile:

I went with Mitsubishi, the AY series connected via Wi-Fi with Melcloud (and therefore compatible with Gladys)

I’ll put together a tutorial in the training at some point :slight_smile:

Wow… fast…
Cool that you stayed with Mitsubishi…

PS: I’m moving in January so purchase and installation of the heat pump will be around March/April, I think…
So your experience reports and tutorials will be useful

The installer came on Tuesday around 9:00 a.m., left at 12:00 p.m., it was relatively quick :slight_smile:

Also, it’s only a single split!

But why, there is a Tutorials category on the forum?

My project is still progressing (notary in 2 weeks) and I’m taking advantage of a bit of time to dive back into the heat pump (PAC) topic that I plan to install..

So, to summarize :
2 ducted heat pumps PEAD-SM71JA / SUZ-SM71VA MITSUBISHI ELECTRIC

  • On the ground floor, it will be simply installed (mechanical plenum not controlled)
  • On the upper floor, it will have a plenum allowing flow regulation of 4 separate zones (the bedrooms and office) by Airzone

For the ground floor, normally no problem given Pierre‑Gilles’s installation; even though it’s a ducted unit the principle remains the same — the heat pump will be controlled by Melcloud (I need to have Mitsubishi’s WiFi communication module added).

However, for the regulation on the upper floor Airzone still gives me trouble (on paper since I haven’t bought it yet either)…
Digging into the Airzone site and the various home automation sites, I find that I need to add a controller Airzone Aidoo. It exists in WiFi, Z‑wave,… and Zigbee. But on the Zigbee2mqtt site, I discover that it is not compatible in the Mitsubishi Electric version (but Mitsubishi Heavy which is not the same thing)…
Then I also wonder whether this module isn’t there to control in conjunction with the heat pump and… if I install it… how will requests coming from Airzone, the thermostats, the heat pump and Gladys be managed… And is the Airzone Aidoo made to communicate with the outside or only with the heat pump? …

So, I no longer know what I should do… I’m going to have another coffee

Why not install Mitsubishi’s connected range directly? The AY range

At my place I have a " MITSUBISHI ELECTRIC COMPACT MSZ-AY35VGK"

I couldn’t answer that

La AY est la gamme compacte qui se fixe au mur (split interne) comme tu as mis. Ce principe est très bien lorsque l’on veut installer une clim dans quelques pièce en appui d’un système de chauffage autre…
Moi la PAC viendra comme chauffage principal pour toutes les pièces de la maison, et la PAC gainable a l’avantage de ne pas avoir un bloc par pièce mais un bloc uniquement central (volume de gaz et risque de fuite réduites, bruit localisé à un endroit, esthétique invisible,…). L’inconvénient principal restant l’installation et le passage de gaines (pour la soufflerie et reprise) vers les différentes pièces… Et que si le bloc interne tombe en panne, tout tombe en panne lol.

L’option wifi est disponible sur ces PAC, donc la connexion à Melcloud sera assurée… d’où le fait que la PAC du Rdc ne me pose pas de problème.

Pour l’étage, avec le Plenum Airzone il y a bien quelque chose à faire…
Si quelqu’un a le temps de lire le document suivant et me dire ce qui peut servir dedans : https://doc.airzonecloud.com/Documentation/AZ6/X6/GR_AZ6_INT_MUL.pdf
Y a beaucoup d’infos qui semblent utiles, mais je ne suis pas assez compétent

For Airzone, if you’re talking about this Zigbee device:

It exposes these properties:

local_temperature, system_mode, fan_mode, occupied_heating_setpoint, occupied_cooling_setpoint, switch (state), linkquality

We are compatible with:

local_temperature :white_check_mark:
system_mode :cross_mark:
fan_mode :cross_mark:
occupied_heating_setpoint :white_check_mark:
occupied_cooling_setpoint :white_check_mark:
switch :white_check_mark:
linkquality :white_check_mark:

If that’s it, we’re pretty compatible in Gladys — only 2 features are missing, but they can be added :slight_smile:

I didn’t understand everything you said… but what I understood suits me… I’ll understand the rest when I have it and when I try to integrate it…

So it’s positive…
Thank you

The rest next year (lol)
