I’m not the person you asked, but I use microchip-based feeders for my cats and the company also sells microchip doors. I’ve been pretty happy with the feeders, but haven’t had any reason to try the doors.
I have two cats - one is allowed outside and eats all the food in sight, and another that’s indoor only and likes to graze, I have their smart feeder and smart cat flap, which allows me to control which cat is allowed to access what and at what time, setting curfews, and seeing if they’re in or out. Would recommend.
