Feeder Robot update - everything was working fine, but the schedules were glitching. I did some troubleshooting, checked reddit, read support articles and finally dropped into chat at Whisker.
Less than 5 minutes later I have a new unit on the way to replace my refurbished unit (which works, but not 100%). SUPER impressed.
I now have both the Litter Robot and the Feeder Robot and can say that I and the Thundering Herd are delighted.
