"thing" dropping off network breaks piston

[M.knuckle]

1) Give a description of the problem
if statement not true when a thing drops of network

2) What is the expected behavior?
evaluate as off or not on
3) What is happening/not happening?
the thing that drops off network doesnt report on/off so piston wont fire
4) Post a Green Snapshot of the piston

the if statement evaluates correctly until something drops off network. when an item drops off network it will evaluate as false. ( if i set evaluation to “are off” or “are not on”). i dont want to write an if statement to check if each thing is online and its status. any workaround that i may be missing?

Anything pulled from my network continues to report its last value for the switch (on or off). What are you getting that is making yours evaluate false?

With that piece of information, we can come up with a workaround.

if i ihave the piston as above, if any of the bulbs drop the piston fails even tho the bulbs last state would have allowed a pass. assume there is an action in “then”. basically i traced and evaluated it live an watched it work when all bulbs were working but the moment one bulb dropped off the statement would evaluate incorrectly. and in my st app the device says unavailable (as expected) and doesnt report the last state. try unscrewing a bulb and letting st realize its not there.
