Re: [weewx-user] Sunshine Duration

Hi Karen - I went and read the paper that is referenced for the sunshine duration method. It describes an empirical approach to estimating whether or not the sun is "shining". To me, as you suggest, if I have a crisp, well-defined shadow, then there is indeed a 6000 K point source in the sky.

Marco - Would you provide more information to help us understand your system ? See the new Problem Reporting Questionnaire (link) for the kind of information we need in order to try to help much better. Thank you.

Re: [weewx-user] Sunshine Duration

I have added a new field in my extension : is_sunshine At each record generation,, the is_sunshine value will be 1 if there is sunshine, otherwise it will be 0. This field is also published in the MQTT stream. See https://github.com/Jterrettaz/sunduration/tree/master > Le 2 mai 2024 à 14:54,

Re: [weewx-user] Sunshine Duration

I would like to get the attribute sunshine yes/no or a value in the MQTT stream to control my shutters if I already have a Davis Pro. I can only find the value of "maxSolarRad_Wpm2". Please give me some advice on how I could evaluate this, or how could the sunshine value per minute be entered

Re: [weewx-user] Sunshine Duration

Jon, If you are interested at the theoretical maximum solar radiation, Weewx provides this value : *MaxSolarRad* . See https://weewx.com/docs/5.0/reference/weewx-options/stdwxcalculate/#maxsolarrad Le jeudi 2 mai 2024 à 08:27:07 UTC+2, Jacques Terrettaz a écrit : > The "sunduration"

Re: [weewx-user] Sunshine Duration

The "sunduration" extension is calculating the total time in a day when there is no clouds between the sun and the Davis radiation sensor. With clouds, the incoming radiation energy is much lower. The formula used in this extension calculates a threshold radiation value that depends on the
