Is there anything like this? I only find ones that are part of other weather systems like netatmo.

ah ye I came across this too. My dad has one at his place that uses this same principle, with the tilting thing, he's had it for like 20 years now, part of an ELV-brand weather station, solar powered, amazingly long lasting tbh
