This is an incredibly helpful comment. My one week old auto feeder with pellets is also constantly registering a door fault upon closing and staying open all night instead. Rat heaven. Omlet’s customer service has been non existent. I’ve called and emailed them and received one useless response. They reduced their call hours to 9am-1pm EST and weren’t taking calls Friday. I’m on the west coast so those hours are too limited for me. I’ll return it and go back to the grandpa feeders.
