unfortunately, this won't work... you need to loop through the
lightbulbs...
try something like:
foreach ($lightbulbs as $bulb){
}
and your if else logic needs a little tweaking so you don't incorrectly
label the "on" lightbulb as being switch #1 since it is also greater
than $temp['room']
see the following manual pages:
