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

## 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.
