Hours between Sunset and Sunrise the next day


Recommended Posts

Hello guys,

would be anyone so kind and help me calculate hours and minutes between current sunset hour and the next days sunrise?

 

local sunset = fibaro:getValue(1, "sunsetHour")
local sunrise = fibaro:getValue(1, "sunriseHour")
 
I would very appriciate having the information, that the night will last xy hours and xy minutes.
 
Thank you very much in an advance,
tampiss

Put this code on a VD button , edit your longitude & latitude ,then , from then mai loop, activate it every 8 hours. 

 

 

local NET = Net.FHttp("api.sunrise-sunset.org",80);
    fibaro:debug("Connecting....");
    fibaro:log("Connecting....");
    local My_lat = 45.8258910496758 ;
    local My_lng = 8.79590749740601 ;
    local response ,status, err = NET:GET("/json?My_lat=" .. My_lat .. "&My_lng=" ..My_lng .. "&formatted=0");
    if (tonumber(status) == 200 and tonumber(err)==0) then
        fibaro:debug("Collegamento OK")
          if (response ~= nil) then
            rem_jsonT = json.decode(response); -- converto i dati ricevuti da "api.sunrise-sunset.org"
            HC2_jsonT = json.decode(fibaro:getGlobalValue("Twilight")) -- apro la tabella memorizzata nelle variabili globali
                      
            if rem_jsonT.status ~= "OK" then
                fibaro:debug("Dati non disponibili")
                fibaro:log("Error-> ".. rem_jsonT.status);
                fibaro:debug("Error-> ".. rem_jsonT.status);
                HC2_jsonT.Status = rem_jsonT.status
                HC2_jsonT.conn_Time = os.date("%d-%m-%Y  %H:%M");
                fibaro:setGlobal("Twilight", json.encode(HC2_jsonT))

            local TimeOffset = 0
            
            mytab = os.date("*t") -- defaults to current date and time

            else      
               TimeOffst = 3600 -- Adjust the Timezone (+1)
            end

anonymous solution is very interesting but after checking API response from sunrise.sunset.org it gives back day duration and then from that you still have to calculate night duration or time between sunset and sunrise. 

 

My solution is simple and still not really calculating time duration between today's sunset and tomorrow's sunrise but if you enter time correction for tomorrow's sunrise then it can be accurate as it gets. Since difference is almost always same day by day you can always add correction in minutes. This code can be used in both scene and VD and function to calculate time duration between two different times is universal and is always calculating difference between later and earlier time. Also one example of nesting function subroutines to make code more simple and easier to debug

So here is that simple code snippet:

I hope you find it useful. Happy coding!
