Ecowitt WN31 / WN31_EP Multi Channel Temperature & Humidity Sensor

Excellent

Very easy to set up. Fit the batteries and automatically links to main sensor. Would recommend.

Useful add on sensors, easy config and good measurement consistency

Bought as add on Sensors for a WS3801 to cover additional rooms. Very simple integration, just set different channels and it worked instantly. Idea for additional improvment: Please also calculate and display the dew point in the ecowitt portal like for other temp/humidity sensors.

Very impressed

In a sense hard to get excited but hey, it just works! I bought 2. One for an outbuilding and 1 for the greenhouse (with the Stevenson screen). Instructions are simple. It is plug and play with my HP2560 console which was showing in on its screen by the time I got to looking at it. Service from WeatherSpares was superb, faster than than I expected.
