Hi @10der

The error would seem to suggest that when it read the value for the lamp, it read nil. Could the device have been plugged out or just went dead for a few minutes.

I think that adding the space didn't fix the issue but just saved the vd again and it worked

 

You try and trap the condition  if you're interested

Put a check for the value (nil, 0 or 1) before you  try and compare it and break if it's nil but message that it was read as nil and not 1 or 0 as you would expect...

I have seen this but the device stays dead until I resolve...

what type of device is it ?

China dimmer  

 

btw, It is good programming practice to always check for null pointers... but it' not solve the issue. AFAIK VD main loop always start as new LUA script isn't it? so when I am trying to run VD manually [Debug] button - I was rcvd same error.... while I not re-create VD via re-saving... my question why.

I not sure what my China dimmer was "dead" but after re-saving VD - unexpectedly come to life
