Glad to hear that!
By the way some folks have modded the WS40 with a low level heater to keep that functioning in your more extreme climates.
I think that's a cool mod that Ecowitt should consider for a future variant of the WS40 rain gauge.
If you search I am sure that you will find it on here.
Thanks. Yes I'm in the process of adding a heater to my WS40. I've read the (very long) thread on the Davis area of the forum and got some ideas. Sadly, the WS40's bucket is tiny in comparison to the Davis so a reptile heater cord will not fit. Got some Nichrome wire which I think will do the trick.
In those conditions do you find the top of the WS80 dome stays clear enough for the solar panels to function? I'd be concerned about that frosting over and limiting the power into the PV cells, eventually draining the batteries. From what I saw in a cold spell here (well, relative for UK) the heater kept the area of the sensor clear OK but I doubt it was transmitting much heat up to the top section of the device... which you can see in the awesome thermal imaging in this post #59 here:

The top of the WS80 can stay iced up for quite a few days after a storm but I use Energizer Lithiums in the unit so I'm not worried about power. I'll change them out once a year.
I think you should do some searching then.. it's not the "odd" value, there's discussions regarding all ultrasonic anemometers, Netatmo, WeatherFlow, Davis.. they all suffer the same problems.
I've read all the topics I can and I'm aware of the issues. I'm not saying ultrasonic anemometers are without fault, just that like any device subject to the whims of mother nature, there's no perfect one for every climate. My snowblower, which is expressly designed to deal with winter, is always needing maintenance and repairs: carburetor icing, belts slipping, ice build-up in the chute, throttle cables frozen and stuck, shear pins...sheared etc. etc. etc. Is it faulty? Nah, it's just that our climate is extremely hard on anything. Speaking of, the attached pic is what my car looked like yesterday (today it's covered in more snow).
Rain and airborne debris in strong winds are a substantial pitfall for them.
About the only type of weather we don't get here. Winds over 60 Km/h are rare in my immediate area so rain being driven sideways is not common. Snow flying sideways and every which way? We get truckloads and so far, no devious snowflake has caused any crazy readings. Must be something to do with raindrops.
