This dzVents script has to run every minute. But only when a Percentage Device has a value is > 0

This is the trigger part of the code

Code: Select all

local Bpump = 64   -- Index of a Percentage Virtual Device


	on = {
		timer = { 'every minute' },
		devices = { 'Bpump' }
	},
	
	execute = function(domoticz, triggerItem)
	if (triggerItem.isTimer) and
	    (device.name == 'Bpump' and device.percentage > 0) then
            domoticz.log('Script is running.', domoticz.LOG_DEBUG)
	else
	    -- do nothing
	end

The log shows I do something wrong with (device.name == 'Bpump' and device.percentage > 0) But I can't figure out what
Who can point me at the right direction?

Code: Select all

Yes, you are doing something wrong

'device' is not a variable that exists in your code. If the trigger is due to the timer then the second argument of the execute function (triggerInfo in your script) is a timer object. If the trigger is due to Bpump being updated (device-rule) then the second argument is a device. So, in case of the timer trigger you want do this:

Code: Select all

if (triggerItem.isTimer and domoticz.devices('Bpump').percentage > 0) then
    --
end

If however you want to do something when the device is updated you can do this:

Code: Select all

if (triggerItem.isDevice and trigerItem.percentage > 0) then
    --
end

In this case, triggerItem is the device being triggered.

Thanks very much.
I have got it working now.

It is not easy to understand the logic of dzVents. But once you got it. It is such an easy way to write scripts.

Looking forward to your Youtube video volmue 2
