It Works!

Very good for the price

It's not easy to say much about a temperature & humidity sensor, but the two WN31s I ordered worked perfectly out of the box (once I'd set the wireless channel correctly!) and as they bear the Ecowitt brand, if these are anything like the rest of the Ecowitt weather kit I have bought so far (HP2551 weather station and WH57 lightning detector) then I should not have any problems with these sensors.

They are accurate and have a long wireless range.

My HP2551 console automatically detected them almost immediately.

Works Great with the App.

Purchase the WN31 along with the GW1100 and 6 of the WH51 they all work great with the Ecowitt IOS application. Very easy to keep track of my grow environment.

Delivery could be faster. All sensors are OK and running in the WS-App
