Which do you recommend?
I got the cheapest timer-based one I could find ($18) and spliced the 5v motor wires with a Shelly switch (flashed for local-only matter).
I settled on this solution after 3 prior attempts with more expensive feeders because none of them let me control portions and regularity adequately, which ultimately comes down to “cycle hopper motor N seconds at T~1~, T~2~, … , T~K~ for K meals/day.”
That’s been doing its job for nearly two years, cat’s weight stabilized, and his feast/famine eating behaviors disappeared, so I couldn’t recommend anything more complex than that.
ETA: only important if you travel but…
Also added a small relay that reconnects internal AA battery pack on power loss. Which converts unit back to a self-contained timer-based feeder.
The only time that has triggered is when unplugging the unit to clean or when I’ve accidentally turned off the power strip’s energy monitor plug. Not important unless you’re away from home a lot and/or outages are common in your area.

$89 isn’t terrible
