Convert text time to minutes after midnight

[paul402]

I have decided to try and integrate my, working for years, Python functionality into Dzvents but I have a problem with my conversion.
The functionality that I want to replicate is
time1 say '08:00'
time2 say '09:00'
if sunrise is < time1 then sunrise==time1
if sunrise is > time 2 then sunrise==time2
if now=sunrise then move the shutter

How do I convert a text time value into minutes after midnight? The help that I looked at suggested building a time with the year, month and day based on 'now'.
Is this really necessary or is there an easier way?

Something like this?

8.00 is 480 minutes after midnight
9.00 is 540 minutes after midnight

shuttertime = domoticz.time.sunriseInMinutes
If domoticz.time.sunriseInMinutes < 480 then shuttertime = 480
If domoticz.time.sunriseInMinutes > 540 then shuttertime = 540
If domoticz.time.minutesSinceMidnight == shuttertime then move the shutter

Thanks for the feedback waltervl but I want to keep the original data in '09:00' hours/minutes format because it is easier to understand and to convert the variables to minutes after midnight. I just cannot see a simple way to do it.
I have no problem with the logic of the if statements.
May be I will use DZvents to call my Python and return a value. Another rabbit hole to go down when you learn another language.

So I think that I have solved part of the problem.

Code: Select all

            local sometime=domoticz.utils.stringSplit(t1,':',convertNumber)
            domoticz.log('stringsplit ' .. tostring(sometime[1]) .. tostring(sometime[2]) ')
            local t1minutes=sometime[1]*60+sometime[2]
            domoticz.log('t1 minutes past midnight' .. tostring(t1minutes))
           

That gives me minutes past midnight for my variable.

Code: Select all

        local currentDate = os.time()
        
        local setTime = '08:00'
        
        local time1 = os.date("%Y-%m-%d "..setTime, currentDate)
        local time1toStamp = domoticz.time.dateToTimestamp(time1)
        
        
        local minutesToSunrise = domoticz.time.sunriseInMinutes 
        local time2 = os.date("%Y-%m-%d 00:00", currentDate)
        local CurrentSunriseTimeStamp = domoticz.time.dateToTimestamp(time2) + minutesToSunrise * 60
        local todaySunriseTime = domoticz.time.timestampToDate(CurrentSunriseTimeStamp,'%Y-%m-%d time')
        
        if time1toStamp > CurrentSunriseTimeStamp then
            domoticz.log('Set time is after sunrise', domoticz.LOG_ERROR)
        else
            domoticz.log('Set time is befor sunrise', domoticz.LOG_ERROR)
        end
        
        
        
        domoticz.log('Minutes to sunrise: '.. minutesToSunrise, domoticz.LOG_ERROR)
        domoticz.log('Time1: '.. time1, domoticz.LOG_ERROR)
        domoticz.log('time1toStamp: '.. time1toStamp, domoticz.LOG_ERROR)
        domoticz.log('time2: '.. time2, domoticz.LOG_ERROR)
        domoticz.log('CurrentSunriseTimeStamp: '.. CurrentSunriseTimeStamp, domoticz.LOG_ERROR)
        domoticz.log('todaySunriseTime: '.. todaySunriseTime, domoticz.LOG_ERROR)
