I’ve had several people write me recently and ask about how to use petfeedd with multiple servos. It’s actually now my most common feature request, so I will definitely be sure that that is added in the rewrite that I am currently working on.
In the meantime, you can run multiple instances of petfeedd using Docker, each pointed to a different servo. I would be sure to offset each servo by a few seconds to be sure you don’t have any voltage drop issues with the Raspberry Pi.
