how use idx iso names

[BartSr]

this an example from the wiki

return
{
on =
{
devices = {
'myDetector',
'roomTemp'
}
},
execute = function(domoticz, device)
if ((device.name == 'myDetector' and device.active) or
(device.name == 'roomTemp' and device.temperature >= 45)) then
domoticz.notify('Fire', 'The room is on fire', domoticz.PRIORITY_EMERGENCY)
end
end
}

I am looking for a way to use IDX iso names as imho this is better to maintain once names should change
I think it's not that difficult but can't find the syntax

[waltervl]

Just replace names with the appropriate IDX.
And instead of
If device.name == 'myDevice'
use
If device.idx == 1234

I just learned using names is more stable so I keep it with names.

[waltervl]

No, names should be unique. So when changing names they still should be unique.

I am used to using IDX in my dzvents script so when I change a name I do not need to care about my scripts. I only need to take care my names are unique (but that is in every use case an obligation)

A tip: When using dzVents scripts and devices I edit the devices involved and write the name of the script in the description to be able to find out where between all scripts this device is updated.
