Astronomical clock

[admin]

For objects you can enable logging and check the time at which the write happens.
You can also use this script to log current sunrise and sunset time:

Code:

require('uci')

latitude = uci.get('genohm-scada.core.latitude')
latitude = tonumber(latitude) or 0

longitude = uci.get('genohm-scada.core.longitude')
longitude = tonumber(longitude) or 0

sunrise, sunset = rscalc(latitude, longitude)

sunrise_hour = math.floor(sunrise / 60)
sunrise_minute = sunrise % 60

sunset_hour = math.floor(sunset / 60)
sunset_minute = sunset % 60

sunrise_text = string.format('%02d:%02d', sunrise_hour, sunrise_minute)
sunset_text = string.format('%02d:%02d', sunset_hour, sunset_minute)

log('Sunrise: ' .. sunrise_text)
log('Sunset: ' .. sunset_text)
