ECOWITT Wireless Multi-Channel Thermometer and Hygrometer Sensor, Temperature & Humidity Gauge with LCD Display, Remote App Monitoring WH31(WN31)

Reliable sensor with a handy display. Communicates reliably to the Ecowitt gateway, which I have feeding into Home Assistant. Frequent updates mean that graphs of temperature in HA (and also on the Ecowitt Weather website) show a smooth curve. Humidity readings are less granular. Battery life is surprisingly good.

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!

Works well when connected to base station

Great!

We got a couple of these to go in our basement and garage and link to our Ecowitt Wittboy weather station The instructions for linking them aren't great, so they took a while to set up, and the display functionality on the Wittboy is limited, but they work well However, they are quite expensive, so would probably go for Zigbee H&T sensors in the future and link to Home Assistant directly

I now have 4 of these additional sensors. Am delighted with them. They take 2 AA batteries and my ECOWITT HP 2511 weather station picks 'em up immediately as soon as the batteries are installed. The console alternates between all installed sensors and the whole system works exactly like it should. Highly recommended to pair with your ECOWITT weather Station. As a test I took one sensor and put it inside a small fridge, not expecting it to work as that fridge was at least 100ft+ feet away. and has metal walls! To my astonishment and delight, it send the data back to my HP2511 without any problems. Absolutely amazing !. If interested ? See my review of the HP2511.

Yet another accurate sensor (WN31) from Ecowitt. As far I checked spot on. -Temperature measured within 0.1C and humidity within 2%. All well within the specification. Bought this as an additional sensor for my garden, mounted in a separate solar radiation shield. For best accuracy, always mount these in effective solar radiation shields or shelters. Certainly a good product, recommended.

Connected without any problems.

Connected right up to my GW1100B. I have this out in my greenhouse to give me some metrics. Been working great.

Funciona perfecto, muy preciso y de calidad. Fácil de configurar con la app de ecowitt

Ecowitt is a great weather station system as you can start off with a quality multi sensor array and gateway console, then gradually, over time, add extra sensors: so far I've added 6 more Temp\Humidity sensors, Temperature probe, Soil Moisture, Lightning Detector, Air Quality, Black Bulb Apparent temp. The Desktop and Mobile apps are great, and the ability to publish your local weather to the community is a plus. Still a few more sensors I'd like to add. Highly recommend this brand for anyone looking to set up a weather station.

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.

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.
