## Questions & Answers

**Q: Do you have wh51 transmits at 433 mhz? what would it be named? wh51a? or wh51c?**
A: My WH51B devices use 914915000, or about 915Mhz. If you are trying to identify which frequency band your device is using, I couldn't do it from packaging. The best answer that I could give you is that if you bought it on Amazon with a US shipping address, then you probably got the 915 version instead of the 433 that you thought you were buying. I understand that if you need a 433, you can contact Ecowitt and they will send you one intended for another country.

RTL_433 can be configured to use the 915 band, though this will mean you have two instances of RTL_433 and the sdr hardware. I do. The WH51B is not a powerful transmitter, and the receiver can't be a long distance away.

I struggled with getting the WH51B to work with RTL_433, so I'll share my config:
<code>
frequency 914915000
sample_rate 250000
protocol 142
report_meta time:off
output mqtt:192.168.0.xxx,events=eco2mqtt[/id]
</code>

If you have trouble, post in the RTL_433 github issues and someone will help.

**Q: What is %ad? how does it relate to any standard measure of soil water content**
A: Hi, the %ad refers to the defaut dry definition on the fixed slope rate linear system.
We recommend you to have a look at the manual(you can download it on our official website) from P8-12 to understand that better.
Any question, please contact us at support@ecowitt.com.

**Q: Can you just leave the wh51 soil moisture sensor in the ground outdoors to constantly check the soil with the gw1000 remotely?**
A: Hi, yes. The wh51 is communicating with the gw1000 via RF signal and the reporting distance is within 300feet/100m(in open area).
After you finish the wifi configuration on the free WS View app with the gw1000, you can upload the data to our own weather server: ecowitt.net.
Then you can remoting the data by visting the ecowitt.net website(need to add your gw1000 device on the website first).
Any other question, please let us know at support@ecowitt.com.:)

**Q: Can this who291 transmit to the lcd display panel and also a gw1000 wifi gateway for logging, at the same time?**
A: Hi, GW1000 can accept the sensor data in the WH0291 and upload to our free weather server: ecowitt.net. So the GW1000 + WH0291 works!
The WH0291 actually is the WH51 sensor with a display.
Any other question, please contact us at support@ecowitt.com.:-)
