Hello and thank you for your feedback.
I’m really sorry but I was wrong in criticizing this integration.
The integration that really posed a problem for me is the one that goes through homekit.
Concerning your netatmo integration in fact it is rather complete on my side I only miss this functionality: true temperature.
I understand that it does not appear in the official documentation and that you do not want to take the risk of integrating it.
Otherwise the rest of your indication is fully functional and I thank you for that.
