Different behaviour of the termostat, less intelligence

[Gert19]

For about 3 years I'm using the Netatmo termostat:

Since some time the behaviour of it has changed.

Last year I was very happy with this:

Now it works more like blocks, less intelligence as it did before:

I've been in contact with support, but they cannot help. Works as designed... they can/will not explain the difference between now and last year.

The boiler is the same. The termostat uses the advanced algorithm as it did before.

Anyone who understands what is going on and why the current behaviour is different than a year ago?

Thanks in advance, Gert - Nederland

Seems perfectly normal to me. Thermostat is full throttle to reach desired temperature, then it stops. What i see (correct me if im wrong) is that heating has hard time to reach desired temperature (big temperature step), thats why now it shows full heating.

Difference to previous chart is, that there is different schedule, on first chart it just maintains temperature, instead of heating to higher one
