New ASCOM driver for Ecowitt weather stations

[chris_g]

HI Ivo,

A quick note, the driver connected to the WS3901 console with no issues and returned normal test data when set to internal temp. However, the delivery didn't make it until late so I can't test the outdoor sensor yet. APT reported an awfully hot indoor temp and dew point, think I moved to Venus!

More food for thought, store the weather telemetry in it's own table. Easier to do searches I would imagine

Hi Ivo,

Got the rain sensor configured, when I reconfiugred the driver to read the outdoor temp, it was good. It's only inflating the temperature if the indoor sensor is selected in the driver. Not a big deal, who wants to know what the temp is inside anyway!

Thank you for this.

Clear Skies,
Chris

Hi Ivo,

Been playing with the sensor, I think there may be something wrong with the dew calculation. The console reports a dew point of 55.8 F but APT shows it at 85.3 F. I checked the test page and it's showing 29.6C from the sensor.

I did some digging on the API and the byte should be #define ITEM_DEWPOINT 0x03 // Dew point (℃) 2 bytes. I ran a python script to pull that byte with a GetLIveWeather call from the console and it returned what the console displayed. If I had to hazard a guess on what might be wrong, I think you're using the Wind Chill byte, #4

Hope this helps.

Clear Skies,
Chris
