Rubik wrote: 23 Nov 2020, 16:01 I recently bought a Netatmo Smart modulating thermostat. Their new modulating product, not the older non-modulating thermostat.
It has been connected to a compatible boiler (Atag A244EC) with opentherm capabilities.

The problem is that it does not modulate at all! It turns the boiler on at full blast for a very long time, so the temperature completely overshoots the setpoint. The radiators become very hot with 70 degrees C. My wired modulating thermostat will hardly ever reach 40 degrees C. My house is well isolated with a decent radiator capacity.
Of course this thermostat behavior results in a very uncomfortable climate.

Attached is a plot of Home Assistant (which I only use for monitoring the thermostat) showing the setpoint (blue), the current temp (red) and the state of the boiler (green).
I also contacted Netatmo support, but their reply will probably take a while.

Anything I can do in meanwhile?

Can I ask you how you integrated this new thermostat in home assistant ? Thanks

Using the homekit setup code on the back of the Netatmo product installation guide.

Hi,

I'm also having this issue, I bought the product specficially so that the boiller gets switched on based on demand fromt the valves.

What is the ETA for this new firmware? Is there a beta program?
