Need to know if i'm in the night time or not

[pipiche]

I have found on the forum the idea to create a nighTime dzVents device. But I'm failing to make it working.
For sure I'm doing something wrong, but cannot find it

Code: Select all

cat test_nightTime.lua
local SCRIPT_NAME = 'testing_NightTime'

return {
    active = true,
    on = {
	timer = { 'every minute' },
        devices = {
		['nightTime'] = {'between 22:31 and 07:59'},
        },
    },

    logging =
    {
        level = domoticz.LOG_INFO,  -- change to LOG_ERROR when all OK
        marker = SCRIPT_NAME,
    },

    execute = function(domoticz, nightTime, item, timer)
	local time_window = domoticz.devices( 'nightTime' ).state

    	domoticz.log('system: '..domoticz.time.rawTime)
    	domoticz.log('Domoticz: '..domoticz.settings.domoticzVersion)
    	domoticz.log('domoticzvents: '..domoticz.settings.dzVentsVersion)
    	domoticz.log( ' --------the trigger---------' )
    	domoticz.log(item.name .. ' seconds ago ' ..item.lastUpdate.raw )

    	domoticz.log( ' nightTime ' ..time_window )
    end
}

There is no switch called nightTime, or there are several devices with that name and dzVents handles that badly.

If you want to test for night time in dzVent, just use the time property:

Code: Select all

	execute = function(dz, item)
	  -- [...]
		if dz.time.isNightTime then
		  -- do stuff only at night
		end
	  -- [...]
	end

Otherwise you must first create your device using the virtual hardware.
In your dzVents triggers, no need to add the device as trigger as nobody should change it. But then, you can also reset it to the correct value. But no point in putting a time interval.

Code: Select all

cat test_nightTime.lua
local SCRIPT_NAME = 'testing_NightTime'

return {
    active = true,
    on = {
	timer = { 'every minute' },
        devices = { 'nightTime' },
        },
    },

    logging =
    {
        level = domoticz.LOG_INFO,  -- change to LOG_ERROR when all OK
        marker = SCRIPT_NAME,
    },

    execute = function(domoticz, item)
	local device = domoticz.devices( 'nightTime' )
	if domoticz.time.isNightTime then
                device.switchOn().checkFirst()
	else
                device.switchOff().checkFirst()
	end
    end
}

in fact I was looking to define my own might time window. So probably I'll have to end up with testing the current time.

This can be done easily too. You still need to create your virtual switch named nightTime (and have only 1 device with this name)

Code: Select all

local SCRIPT_NAME = 'testing_NightTime'
local DUSK_TIME = 'at 22:31'
local DAWN_TIME = 'at 7:58'

return {
    active = true,
    on = {
	timer = { DUSK_TIME, DAWN_TIME },
        },
    },

    logging =
    {
        level = domoticz.LOG_INFO,  -- change to LOG_ERROR when all OK
        marker = SCRIPT_NAME,
    },

    execute = function(domoticz, item)
	local device = domoticz.devices( 'nightTime' )
	if item.trigger == DUSK_TIME then
                device.switchOn().checkFirst()
	elseif item.trigger == DAWN_TIME then
                device.switchOff().checkFirst()
        else 
            	domoticz.log('Unknown trigger for nighTime ', domoticz.LOG_ERROR)
	end
    end
}

then, in your other scripts, you can test for:

Code: Select all

domoticz.devices('nightTime').active
