Thanks in advance

did you try it?
the optical interface should be a couple of ir emitter/receiver, but i fear the application layer (i.e. a password needed to start communication?)

Ciao, sei riuscito a trovare una soluzione? Sono anche io in cerca di un modo per leggere i dati e trasmetterli ad home assistant.
Grazie

In realtà non ci ho neanche provato
Mi accontento di calcolare il consumo del gas in base alle ore di accensione del termostato (Netatmo)… ed è piuttosto preciso…
In un anno ha sbagliato meno del 5%

How do you do that? Can you share your template?

Here it is…

climate.casa is the Netatmo thermostat entity id


template:
  - sensor:
      - name: caldaia
        state: "{{state_attr('climate.casa','hvac_action')}}"
  - sensor: 
      - name: "Caldaia Consumo Gas"
        state: "{{states('sensor.caldaia_ore') | multiply(1.75) | round(2, default=0)}}"
        unit_of_measurement: "m³"
        state_class: total_increasing
        device_class: gas

Great ideia, do you use the consumption reference in the manual of the heater? I think I need to adjust every day until get a good number, this will help a lot!

no… I calculated it based on my statistic data I had from the past (many years) … monitoring both gas consumption (from billing) and running duration (from Netatmo cloud data) …
So it is quite precise…
:wink:

Hi Stefano, I have the same thermostat and I just added your code. I can see the climate.casa switch between idle and heat, but sensor.caldaia_ore always remains 0. Am I missing something? Thanks in advice!

Forgot to mention you need to create helpers with Utility meter…

io ho parlato con un ing. di unareti. La porta ottica dei G4 è disattivata perchè… boh non so perchè. ma dopo averci provato e riprovato mi sono fidato della rispostaccia e mi sono messo l’anima in pace. peccato
