Review: Perfect pairing with an Ecowitt hub/station - 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!
Review: Decent Price and does what it says. - 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.

## Questions & Answers

**Q: Can you confirm that these sensors are 868mhz for the uk**
A: Yes. It's also on the box fairly clearly so you can check before opening.

**Q: Can this be paired with the ws2320 weather station?**
A: It does not show up in the specs, so short answer is no.
It might via the GW100 Gateway and through that it certainly will show up on your webpage as the device [& CH No.]
However, a HP2551Console has a built a in gateway will add support for 8 more sensors. < I would contact Ecowitt directly via customer support before pursuing this option.

**Q: Hello, i do not understand the two options available. i need remote as well as the moisture probe. which option do i need to purchase?**
A: Are you buying NEW?
The Console HP2551 Or Better is essential for all the gadgets to work.

With that choice [or better] you can add 8 more sensors, Temps, 1xLightning, Airs, Soil, Water etc. up to 8.

### ⭐⭐⭐⭐⭐ Accurate, WN31 sensor
*by G***V on 27 May 2024*

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.
