ECOWITT WH0291 GW1100 868MHZ Soil Moisture Tester Plant Soil Moisture Sensor Meter with Digital LCD Display for Garden, Lawn, Potted Plants, Indoor and Outdoor

ECOWITT WH0291 GW1100 868MHZ Soil Moisture Tester Plant Soil Moisture Sensor Meter with Digital LCD Display for Garden, Lawn, Potted Plants, Indoor and Outdoor

Q: Do you have wh51 transmits at 433 mhz? what would it be named? wh51a? or wh51c?

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: frequency 914915000 sample_rate 250000 protocol 142 report_meta time:off output mqtt:192.168.0.xxx,events=eco2mqtt[/id] 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

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?

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?

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.:-)
