Understanding $device, $devices, $currentEventDevice, etc

[orangebucket]

I think the real question is when is $devices filled in with anything? $device is used for a for each loop. Is there any other time when $device has a value? When does $devices get a value? At least that’s my question.

I thought that was the question too. One possibility might be the list of devices used in a ‘with’, but I’m not sure how useful that is to users.

Hi,
How did you make the statement like {$device}'s temperature is greater than 50ºF? The closest one I could do is any of {$device}'s ,

Thank you

$devices is filled in:

• it is restored from a scheduled wakeup
• it is set when you execute an action with a list of devices

So otherwise it would have nothing in it. (ie when it completes a set of actions it clears it out)

$device is filled in

• it is restored from a scheduled wakeup (as is $index)
• inside of a each statement it is filled in (as is $index, and if you used your own counter variable)

$currentEventDevice is filled in on piston start

• if it is a schedule run, it tries to pickup the device that originally scheduled the event
• if it is a device event, it uses the event device
