Review: Simple but does the job nicely - This has been the best weather station I've had. It's simple and the network conneciton can be a little fiddly but overall it does the job. Recommended
Review: Excellent product, works as advertised. - I purchased two of these units, one to keep upstairs and one for the basement. My upstairs is over our garage so it's always warmer in the summer, colder in the winter. Now we can have an idea of how much different the climate will be, same for the basement. Connectivity was a breeze, just have to change the dip switch if using multiples for the different channels.

## Questions & Answers

**Q: Can i use wh32 for wh31? and 8 sensor max. for one gateway?**
A: Hi, you can't use the WH32 for WH31.
Here are the differences between the two sensors:
1. Only the WH32 sensor data can display "Outdoor Temperature and Humidity" on the WS View app when work with GW1000.
2. The WH31 sensor data will display "Multi-channel Temperature and Humidity" on the WS View app when work with GW1000. 
3. One GW1000 can only receive one WH32 sensor data.
4. One GW1000 can receive up to 8 WH31 sensor data.
5. The WH32 sensor data can be uploaded to weather underground, while the WH31 could not.
6. Both the WH32 and WH31 data can be uploaded to ecowitt.net.
7.The WH31 can work with HP2551/HP3500/HP3501

Any other question, please let us know at support@ecowitt.com.

**Q: Is this sensor ok for outdoor use?**
A: Eccowitt has a sensor for outdoor use that you should buy.  (WH32) The WH31 will take channel 1 to 8, while the WH32 is independent and has it own channel assignment so leaving channel 1 to 8 open for other temp/humidity sensors. Physically WH31 and WH32 are the same case.

**Q: Has anyone had success with a WH31 in a freezer or refrigerator?**
A: Hi, you can place the WH31 in a freezer or refrigerator, since the working temperature for it is -40C to 60C(-40F to 140F).
Any other question, please contact us at support@ecowitt.com

**Q: Can this sensor be calibrated? Thanks!**
A: Hi, yes, you can calibrate it on the WS View app:
On Live Data press More - select Calibration - select Multi CH T&H Calibration 
Then you can set the value you want.

### ⭐⭐⭐⭐⭐ Excellent product, works as advertised.
*by D***E on June 6, 2025*

### ⭐⭐⭐⭐⭐ Goes PERFECTLY With My Home Automation
*by E***A on April 15, 2025*

I couldn’t be happier with this ecowitt sensor. Setup was quick and hassle-free --> it paired easily with my ecowitt gateway (the gateway is what is tied to my home automation). I actually keep this sensor in my freezer to prevent food spoilage incase there is a problem with the power or freezer. The readings are accurate and update frequently, and the build quality feels solid. I especially appreciate how compact and low-profile the sensor is --> it's easy to mount or tuck away without being obtrusive. The battery life so far has been excellent as well. If you're looking for a reliable and flexible way to expand your home climate monitoring, this sensor is absolutely worth it. Highly recommend!
