Hello Susan,
Thanks for the answer. I am experimenting with the "StdCalibrate" section
in the weewx.conf.
A comparison of the reported values with the UV index according to the
console showed the following:
0 = uv <= 100 uW / cm²
1 = uv> 100 uW / cm² <= 450 uW / cm²
2 = uv> 450 uW / cm² <= 900 uW
In my HP1000 weewx driver, I use the formula (in Python)
int(round(data_value)/256)
where data_value is the value I read directly from the device itself.
The resulting values seem to match those displayed on the console itself.

Hello Vince,
Thanks for the answer. I think it's not easy to convert. In your link, I
read, "The index is equal to the EAS-weighted irradiance (in watts / m²) x
40. An index of 10 corresponds to an EAS-weighted irradiance of 0.25 W /
m², but if I convert my values this does not fit the index o

Some quick googling seems to say it might be a little complicated, but I
did find one Davis link that might help...
