I am disappointed - after getting the weather station delivered super fast, I installed the base station. So far so good. Then I put the batteries in the outdoor station, everything was fine, the connection was established, the temperature was displayed in the app. So I put it on the window sill (about 3 metres from the base station). The temperature goes down (it is cold at the moment) up to 5 degrees, everything is OK and displayed - but then the communication fails completely. That can't be it, can it? I changed the batteries (although they came straight out of the box) - indoors it works but outdoors the communication fails again below 5 degrees. Even moving the base station closer does not help. Has anyone had similar experiences?
