Netatmo products during service break

Hi,

I’m a beginner with HA and have currently my lights controlled over Philips Hue (Ikea bulbs too). In addition, I have bought Netatmo Weather Station and have it working with HA. The ultimate plan is to have everything controlled with HA in the new house to be builded this year.

My plan was to buy Netatmo cameras too, but Netatmo service break couple of days ago got me to realize that Weather Station stops working if Netatmo servers disappear for reason or another. Would that be the case with the cameras too? I found out from some forum that the cameras continue to work with HomeKit (locally) even if internet connection is lost. But what is the case with Home Assistant? It should be possible to store recordings to a local FTP server but has anyone tried this without internet connection? Not much of a security product if it stops working…

I’m disappointed with the Weather station. I read that someone use that for controlling heating and air condition and I was playing with the idea too; not such a good idea currently.

Is there local API to the Netatmo devices or is the only possibility to fetch the data from Netatmo servers?
