A special kind of persistent variables: history = true[edit]
In some situation, storing a previous value for a sensor is not enough and you would like to have more previous values for example when you want to calculate an average over several readings or see if there was a constant rise or decrease. Of course you can define a persistent variable holding a table:

Code: Select all

 return {
        active = true,
        on = {
            devices = {'MyTempSensor'}
        },
        data = {
            previousData = { initial = {} }
        },
        execute = function(domoticz, sensor)
            -- add new data
            table.insert(domoticz.data.previousData, sensor.temperature)

            -- calculate the average
            local sum = 0, count = 0
            for i, temp in pairs(domoticz.data.previousData) do
                sum = sum + temp
                count = count + 1
            end
            local average = sum / count
        end
    }

In pairs isn't valid anymore?

You need to use forEach to iterate over the values. See the docs about this.

I quoted out of the docs!

Eh yeah. Guess I didn't get your question. Sorry. What exactly is the problem?

How do I convert this code from lua to dzVents:

Code: Select all

for i, v in pairs(devicechanged) do phone = i end
print('<font color="green">' ..phone.. ' is home</font>')

[dannybloe]

Code: Select all

domoticz.changedDevices.forEach(function(device)
	domoticz.log(device.name .. ' is home', domoticz.LOG_INFO)
end)

[DewGew]

Code: Select all

domoticz.changedDevices.forEach(function(device)
	domoticz.log(device.name .. ' is home', domoticz.LOG_INFO)
end)

GREAT Thanks

Edit:
Correct code is:

Code: Select all

domoticz.changedDevices().forEach(function(device)
	domoticz.log(device.name .. ' is home', domoticz.LOG_INFO)
end)
