Hi everyone, I'm a system integrator, I'm trying to integrate a Vitodens 200W boiler with the Home Assistant home automation system. 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.
