There is his VIessmann API but although he has already managed to integrate it a few days ago now it doesn't work anymore. I tried and tried, read many forums and tried various solutions. The Wifi module sees a good signal, over 60%, says it is connected to the backend but then it is unreachable. Does anyone have experience, ideas...? Thanks to anyone who will reply.</P> Fri, 16 Dec 2022 11:39:25 GMT https://community.viessmann.de/t5/The-Viessmann-API/Viessmann-connection-200W-with-Home-Assistant/m-p/292191#M1235 impiantispeciali 2022-12-16T11:39:25Z https://community.viessmann.de/t5/The-Viessmann-API/Viessmann-connection-200W-with-Home-Assistant/m-p/298536#M1289 <P>Hi <a href="https://community.viessmann.de/t5/user/viewprofilepage/user-id/61841">@impiantispeciali</a>, is it possible to use the ViCare app for the device and do you see any data there?
