I am a weather buff, and tech snob! So this is where my 2 passions meet. I was in the market for a modular weather station / system, and came across the Ecowitt suite of products. Affordable, and good reviews is ultimately what made me pursue the product even further. I was attracted by their modular approach, whereby I can locate each sensor in optimal siting for their respective measurement. In total (thus far...) I have purchased the gateway, the outdoor temp / humidity sensor, 3 indoor temp / humidity sensors, and the rain gauge. Anemometer and soil moisture meter will be added at a later date. The sensor pairing process is automatic. The range is fantastic. The accuracy seems bang on. The presentation of data that is published and viewable on the ecowitt website is well thought out and pleasing to the eye. Top kudos to Ecowitt team. The data viewable in the WS View app is not as good as the website view, but just remember that the WS View app is just used to help in the setup process, and only the full enjoyment and benefit comes when you publish your weather data (either public or private) to the Ecowitt site.

This has been the best weather station I've had. It's simple and the network conneciton can be a little fiddly but overall it does the job. Recommended

Połączył się z moją stacją sbs-ws-500 zaraz po włożeniu baterii. Jedyne co trzeba zrobić to wybrać kanał. Działa przez trzy ściany i gruby izolowany sufit. Sprawdzony także w tunelu foliowym poza domem. Także tam jest w zasięgu stacji.

Purchased this to like to my Wittboy weather station, I wasn't expecting much but wow. I have a bike shed that gets alarmingly hot, and I use extractor fans to toggle at certain temperatures, I've used 3 smart thermometers but they all seem to have substantial delays in readings not to mention the bike shed is made of steel so signals are an issue. But with these, they update almost real time and the fans are doing a much better job of reducing temperatures by kicking in earlier, signal is perfect no matter where they seem to be placed on the property and all appear accurate out of the box. Also are probably the cheaper thermometers I've purchased yet perform the best. Battery life also so far seems very good, I ended up buying two more units and have gotten rid of all my other smart thermometers. Works nicely with Home Assistant also. Very happy indeed!
