It’s me who thanks you! Great experience, me who is a novice in home automation, it’s an honor for me!! 
Could you be more specific about your air conditioning model? (Brand, model, remote control references…)
You never know
From memory, it’s an Atlantic air conditioning system (Fujitsu outdoor unit) aryg30.
Reversible ductable air conditioning with 3 zones.
I’ll check the paperwork for more precise information! 
Look on this page if you see a common (or very close) reference with your installation (especially at the level of the remote control)…
These are the IR protocols (infrared remote controls) natively supported by Tasmota (and others…).
Or wired as well…?
The 433 MHz is also quite well managed for a low investment by Tasmota…
We can discuss it in PM or in another thread if you want, to avoid clutter…
Hello
This screen allows you to control the air conditioning. Then, if I am not mistaken, the other remote controls allow you to increase the temperature. This increase will be done by opening motorized flaps that are positioned on 3 duct networks (3 zones).
These flaps can be positioned directly on a plenum and then the network is distributed in 3 or they are dispersed.
Normally, on the flaps positioned on the plenum, they are in 1-10V, in other words, they open from 0 to 100% (the new generation), otherwise it’s all or nothing.
Thank you @Filnea for these details! Since I didn’t have this air conditioning installed, I confess I’ve never gone into the attic to look at the topology of the thing…!
My remote controls by zones allow several things:
So I confess I’m having trouble knowing what to use to automate this.
I would simply have liked to replace this central box with one that I can control from my smartphone (or Gladys if I’m dreaming a bit), because that’s where the settings for scheduling / operating mode / general temperature / etc… are located.
I understood that solutions like Qoora, Nest, etc… are more designed to replace a simple IR remote control… 
It’s a shame because the operation is what I’m looking for!
I’ve got a mate who works at Cedeo, I’ll ask him
A small tip: nodon offers to make a proposal for their equipment to connect the hardware. Just give them the machine specifications.

I’m on their website, I’ll take a close look, thank you!
I’ll add this little screenshot because the connectivity with my solar panels has returned. At this moment, I see this:
Actually, the production and consumption curves are combined because my photovoltaic system takes advantage of the low home consumption AND the sun to heat the hot water tank, rather than selling the surplus.
It’s still prettier with a nice working graph!
My brother installs air conditioners in the Toulouse area where we live. And he told me that there is no real low-cost solution at the moment that manages all possible settings.
The Heiwa brand offers a Wi-Fi module for Split units that works well because we had this brand before, and there is a smartphone application.
Then there is Delta 8000 from Delta Dore, but it’s a closed protocol.
I’m not surprised unfortunately…
It’s not the end of the world, I use my hands lol
What’s more annoying is the finer management of presence/absence. Now I’ll have to anticipate and use my brain… Complicated! 
For the air conditioning, I installed DIY split units (you need to be a bit of a handyman) from the brand Qlima, which come with a Wi-Fi module. I haven’t tested this module yet, but there is a domoticz plugin in Python for controlling it on GitHub like GitHub - awalsum/Qlima: This is a first attempt to create a plugin to control Qlima wifi airconditioners through Domoticz. It is based on a library by NeoArcheron and Mac_Zhou. · GitHub and also a Home Assistant plugin GitHub - mac-zhou/midea-ac-py: Home Assistant Custom Integration for Midea Group(Hualing, Senville, Klimaire, AirCon, Century, Pridiom, Thermocore, Comfee, Toshiba, Carrier, Goodman, Friedrich, Samsung, Kenmore, Trane, Lennox, LG and much more) Air Conditioners via LAN. · GitHub and a tool for discovering air conditioners on a LAN GitHub - mac-zhou/midea-msmart: This is a library to allow communicating to a Midea AC via the Local area network. · GitHub.
This will surely help people who want to install their air conditioning!
There’s something new from Tado to control air conditioners and heat pumps
More info here:
It’s a bit like Broadlink because it’s infrared but only for a single device.
And it’s at an affordable price
