Newbie Rule Machine - Toggle Switch Set-up

[Crispy]

Sorry, if I wasn't clear enough. Food is a non-smart device. Battery operated timer.

Assuming that the 'dumb' timer is consistent then you can setup a 15min triggered rule and add in the food time as a condition.
Triggered every 15min.
If Time between FoodStartTime (- 15 min to make sure the pump be off for when the food actually drops) and FoodStopTime then
Pump Off
else
if Pump on then
Pump off
else
Pump on
endif
endif

That should work without having to use the pause or wait stuff and satisfy the KISS requirement

I used TechMedX's suggestion with the virtual switch and it's working well (screenshots helped). Thanks everyone.
