I’m trying to find a weather station with ethernet connection (or PoE even better), as I need to place it on a roof which is very hard to access and with thick concrete walls that block radio signals. So far I haven’t found anything. Any ideas?
If worse comes to worse you could consider instead of an ethernet cable up near the roof, an antenna cable leading to outside nearby - the antenna could then talk to the weather station? Maybe don’t even need that long an antenna cable going up to the roof, just getting the end of it on the other side of the concrete walls may be enough?
