Are you sure? About feeder? I don't have a working controller yet, so I can only look at the code!
But I can't see dedicated port for feeder:
// -Updated feeding to allow not including outlets in feeding routine
Looking at code, it seems that only notify is implemented (and some power off on 8 predefined relay ports!), could be done, but currently I'm a little out of time.
You could something like this:
Connect Aux2 (A7) to relay/feeder,
set timer for feeder
set all power outlet to off (maybe a filter pump is not a good idea), except AUX2 to on.
It should work, without code change …
Try some combination and write back, for other users!!
As I wrote previously I don't have a working controller, so I could miss something ...
