I have not. In the past it has taken 2+ months to get a reply on an open ticket.

Something new this afternoon : my application has been updated. Now, confirm button is ok, but I have a 400 error message if I want to change heating curve number.
If I want to change water temperature, no error message, but it does not work.

Maybe we are going to receive an update for the thermostat :geek:
Thermostat modulant - version logicielle interne 6
Relais - version logicielle 22
3 vannes - version logicielle 89 - priorité ECO

Station météo V4 version logicielle interne 200
Module extérieur version logicielle interne 52

I get the same behavior with 400 error even without updating the app. The issue is clearly on the server side.
It seems like they're working on it, so that's good.

Today I received a message today from Netatmo:

Thank you for contacting Netatmo Customer Service.

We are investigating the problem to solve it as soon as possible.

I will contact you as soon as we have an update.

Now that setting the heat curve is working again, I'm observing that it's flat... meaning the flow temperature does not increase as outside temperature decreases.
My boiler shows the temperature commanded by the thermostat and it's the same for all outside temperatures between -1 and +8 degrees C.

Here are the values I observe:

Heating curve ---- flow temperature

0.1 ---- 22
0.2 ---- 25
0.3 ---- 28
0.4 ---- 31
0.5 ---- 34
0.6 ---- 37
0.7 ---- 39
0.8 ---- 42
0.9 ---- 45
1.0 ---- 47
1.5 ---- 61
2.0 ---- 74

For 3 and 4 degrees, I got slightly lower values, but it was strange to have lower flow temp for lower outside temperature, so I initially discounted them.

I tested on multiple days where the outside temperature varied between -1 and +8 degrees C, and it's basically the same flow temperature as shown in the chart below.

Anyone else observe similar behavior?

Hi vicentiu,
Do you have netatmo weather station?

I have heating curve value 1, and flow temperature is usualy between 50 and 65 degress. These days outside temperature is between -2 and +2. But I am not monitoring flow temperature all the time, my boiler (Viesmann Vitodens 100) has no tool for that, only from time to time I take a look on the boiler screen.

Generaly, I am happy how it works now, setpoint temperature is much more stable then with classic Netatmo thermostat, with almost no oscilations.

How did you get flow temperture graph? From some boiler tool?
