Modern and accurate

Very nice and modern looking station without moving parts .Not much need to maintenance ,just cleaning few times a year and battery change.It was smaller and lighter than I tought so even better.Worksmanship feels great ,also materials feel very good quality.Only thing I find little strange is that it can be attached only 1 inch or smaller pole but that isnt any problem at all ,I was just suprised.
Station seems very accurate when comparing with my old station ,internet weather apps and specially official weather station just few km. away .It was easy to set up and connect online ,Ecowitt app works well and its simple to make adjustments and setting.It lets easily to observe my own weather station at home plus thru weather map other stations around the globe.This ,paired with some extra sensors new console with build in CO2 measuring ,is definetly best weather station I ever had during mu 30 year intrest to weather.I highly recommend this because overall value ,accurate measures and reasonable price plus all easiness and simpleness to every weather intrested who wants a home station.

Easy setup. Easy connection to
I want to keep long term wind records locally and summarises them too much (4 hour slices). So I need to work out how to get records locally.
Plus your email to judgeme really sucks.

Now my personal weather station is fully functional. The WS90 works flawlessly and very accurately. It even measures the minimum wind gust. I can't speak about the rain sensor because the weather is cold and snowy. Similarly, I can't speak about the thunder sensor, but I'm keeping an eye out.
The prices are more affordable than in European stores. The delivery was unexpectedly fast.

Great compact weather station with no moving parts.

Great compact weather station with no moving parts.
Had up to now one rain event (2.7 mm) which was in line with a manual rain gauge I had in parallel. I mention this, because the haptic rain meter of the WS90 is widly discussed. Let‘s see how good it will be with hevy rain, long rain events, etc.
Th first week, it was great.
