Does anyone have any experience with self-cleaning cat litter boxes? The ability to connect one to Home Assistant doesn’t really seem useful to me - maybe it would be nice for HA to alert you when the litter box needs to be changed. But I’m really just curious if any particular model of self-cleaning litter box is any good - even by itself, without any “smart” features. We now have 4 cats and it would be nice to not have to clean litter boxes manually 1-2 times every day.
