I agree with Dendrite. Plugging the snow sensor into the rain port would be preferable and makes the most amount of sense. I don't understand why anyone bothers to measure precip in the winter when the tipping bucket heaters result in as much as 40% evaporation!
Please take a look at our radar rain gauge Openvista, radar wave is not affected by frozen layer on its top cover, besides it generate obvious heating itself.
This one is similar to Lufft's.
We can make it compatible to Davis, Plug and Play.
The only thing matters is its power consumption: 180mA@12VDC.
So the solar power CAN NOT supply enough power for it, it asks for extra power supply.
It doesn't have evaporation problem, radar wave detect rain drops when they are falling down in the air.
HY-RS2E radar rain gauge cost 430 USD/UNIT/FOB CHINA, and I may be able to apply extra discount for who would like to take first "bite".
I suppose everyone here is waiting for test result from Dendrite, hopefully, we will ship goods to him next week, thank you all for your patience.
