Get UV values.

[paul402]

On the Weather tab I have all the usual items including UV levels.
I have several DzV scripts running to control and monitor lights, blinds/shutters, radio etc based on time of day and sunrise/sunset.
I want to add to the shutter control that when the UV level is >= x between certain hours then particular shutters should drop until time y.
But I can't seem to work out how to do it.
Can someone give me a clue please.

I use the dzVents script below to control my sunscreen. One of the conditions I check is uv. Please have a look. Happy to help if something is not clear.

Thanks! I see now that I had just used my "Label Name" rather than "local uv_value=outside_sensor.uv".
I had used it correctly for the other sensors!
The leg up is much appreciated. Sometimes you miss the little things.
