Now fixed: The station sometimes makes horizontal lines(same values) 5 to 6 hours every Day. Bresser explain it with a network error. Maybe they are right, but ther is no problem with internet or streaming radio and tv? I have mobile network LTE 4G with a fine connection and outdoor antenna. I tried to install it another place with fiber network, and there was no problem. Where I live I only have LTE network, can anybody help? Tried different routers and sim, but no solution! Solution found: A no public firmware from Bresser, send by mail!
