Wonderful. So the optimal choice should be Anticipation + PID. Right?
Meanwhile i'm going to check the FAQ

Hello,
I have installed my thermostat J064232 last Thursday, and I don't see any information regarding the calculation of the temperature, nor PID algorithm.
Can someone help me on this?

Hi Paolin,
Your Thermostat Netatmo is currently learning the behavior of yor heating system in order to calculate the adapted parameters for the advanced heating alogrithm and the heating prediction option.
Usually, these options should be automatically proposed to you in the next two weeks.
Thank you

Thank you Gaby.
So I'll just have to wait and see. By the way, the firmware of the thermostat is still v18. I have heard that there is already v25 or something. Do I need to upgrade it?

Hello,
i have installed my thermostat (sn: j04451e) in october, after a two weeks it has see me the message "the characteristics of the house haven not yet been calculated etc..". But today i can't select nothing in the advance settgins mode by the webapp to use PID instead of hysteresis. I would like to know if the option "PID" is on or not.

thanks in advance.

Hi mdibari,
Before we can propose the advanced algorithm on your Thermostat, the heating scheme detected by the Thermostat suggests that your heating system is not powerful enough (probably a low water temperature in the boiler).
If this is the case, can you increase this temperature if possible?
If yes, I suggest that we wait for the next week so we can recompute the PID gains and propose it to you.
If not, the regulation using the hysteresis regulation mode is quite good in your case and I would suggest to keep it.
Thank you

thank you for your proposed Gaby.
I live in my apartment for a couple of months and I'm doing some tests on my heating system.
I have no problem to increase the temperature but how do you know that the temperature heating system is not enough ? The heating system takes too long to return to the set point temperature?
how should be the correct heating scheme?
I apologize for all above questions but I'd like to figure out how to use all the informations got by the thermostat.

Thank you.

Hi, another one has been installed for a week and not using PID yet; j0443fe

Thanks

Hi, I had to swap my faulty thermostat for a new one, could the previous data be merged with the new data so I can switch to PID mode?
Old thermostat was j0443fe, new one is j0634b2

Hi Spongefactory,

your old measures have been transfered.
If their is enough data, your house parameters will be recomputed today.

Best regards
