– Wireless Digital Thermometer Hygrometer Monitor - Temperature Humidity Meter, WH31(WN31) LCD Multi Channel Sensor (1 PC) for Home Office

Nice, I'm able to track temperatures in many different areas of my house, with my GW2000A hub, for summer cooling and warming trends, and winter cooling and warning trends. I'm experimented with different cooling and heating ideas, which will hopefully show me which cooling/heating ideas work better. Update 2025-11-18 One of my new three is in my chilly loft, with two Ni-MH AA's, another in a outbuilding, with seven of the eight with Alkaline AA's. The signal strength and battery charge telemetry look good for all so far, and will hopefully stay so for many more months. If the loft Ni-HMs last enough, I may switch to using Ni-MHs in all of them, to save having to buy/keep so many spare Alkaline AA's. So, I've got 10 Temperature/Humidity measurement sensor units being logged now, including the hub and WS69; but I'd prefer it if the hubs could support at least 2 more such sensor units. These sensors show the benefits of coverage and various insulation, including Double Glazing, in unheated areas. Fine Offset's, and other kit with regular temperature and humidity logging, made it trivially easy for any rational people, with seeing eyes, to identify, using the Scientific Method, that cloud (water vapour) is the real "greenhouse gas", NOT CO2! This made the criminality of the unscientific, very political, anti-Carbon propaganda, and the consequent fraud, harassment, and unjust enrichment, for decades, blindingly obvious.

Having just bought my Ecowitt HP2564 weather station I was keen to expand the functionality inside the house with further temp / humidity sensors so I can monitor these values around the house. These are really easy to install. Just add batteries and at the same time set the 'jumpers' to which channel number you require and your preference for measurement in F or C. Screw a small screw into the wall (provided, the screw not the wall) and attach using the keyhole on the back and off you go. My HP2560 display picks up the new 'channel' immediately and includes it when auto scrolling through. Job done, no faffing, which suits me fine.

I bought this as an additional sensor for my Watson WS8686 weather station and it works perfectly. Easy to set up, just use the switches to select channel and C or F put the batteries in and you're done, console automatically connects to sensor. If you don't have a compatible weather station you will need an Ecowitt wireless gateway to view on your phone and the WH32 to post to weather sites as most sites other than Ecowitt.net don't show data from additional sensors.

An excellent item that works well with your weather station. A great addition to anybody’s set up. Ideal for placing in a log store or outbuilding / shed.

This wireless indoor/outdoor temperature and humidity sensor works really well. I have the Gw1100A Wireless gateway and it connected immediately. It's good that you can connect 8 of these sensors to the unit, in addition to several other weather sensors. I've dropped 1 star due to the fact that this doesn't update the outdoor weather to 3rd party sites, such as Weather Underground. It turns out that you need the WH32 sensor, which look similar but only uses 1 channel. The WH31 sensor can be used in various locations around the house or garden, but won't upload to 3rd party sites. I fortunately, Amazon don't sell the WH32 at the time of this review. I'll keep this to locally measure the external temperature for now and have ordered a WH32 via the manufacturer's website. This will be used as a room sensor in the house afterwards. Apart from the above, this is a good value sensor and has a good range on it. You can also view the temperature and humidity on the device itself, meaning that it can be used as a standalone device. Definitely recommended, as long as you understand the limitations outlined above. If ordering the WH32 model elsewhere, make sure you have the 868Mhz version for Europe as US and other versions use a different frequency.

Really enjoy using these sensors and weather station. Simple to set up, use the switches to select an unused channel, put the batteries in and the weather station picks the new sensor up automatically.

30 months ago I purchased from Germany the HP1000SE PRO Froggit Weather Station which I can't recommend too highly. At that date the Ecowitt (Chinese made) was not available in the UK. It was climate change and the effect of less Summer rain on my vegetable garden that drove me to make the purchase but I am in construction so weather has always been more important to me than News. I bought two more of these (I had three, one in the Greenhouse, one in the Hall and one in the roof void which we use for starage) because energy costs have driven us to reduce CH temperature to 18°C. One was to move around to different rooms and the 2nd for the garage where I wanted to monitor the temperature of our 40kW solar battery store. You must add a Gateway to get full utility from these but they will then display temperature and Humidity graphs year on year and you can set alarms (which I do for the greenhouse).

As advertised

Väldigt smidig och fungerar klockrent. Supernöjd. Har kopplat in flera sensorer och anslutit mot Home Assistant

It works as expected. No problems. Recommend.

Perfetto , si collega al gw dal garage al -1 all'abitazione al terzo piano . Batterie durano tantissimo

Sensory łączą się nie tylko z dedykowaną bramką WiFi. Połączyły się z moją stacją sbs-ws-500 i dobrze pokazują temperaturę i wilgotność we wszystkich pomieszczeniach. Mogę je obserwować zarówno na stacji jak i w aplikacji Ecowitt. Polecam.
