Hi Everyone,
I’ve forked the PetSafe integration GitHub - dcmeglio/homeassistant-petsafe: Integrate PetSafe Smartfeed feeders an Scoopfree litter boxes into Home Assistant. · GitHub as it seems to not be in active development any more.
I’ve added support for PetSafe SmartDoors Connected Pet Door to my fork here: GitHub - ThomasHFWright/homeassistant-petsafe: Integrate PetSafe Smartfeed feeders an Scoopfree litter boxes and SmartDoors into Home Assistant. · GitHub
If you use this and find it useful I’d really appreciate if you could give my repo a star 
This should still support the PetSafe feeders and litter boxes, but I don’t have those to test with. It’s a new integration entirely so runs separately to the existing PetSafe integration. So you can decide whether or not to include the feeders and litter box devices you may already have in this integration while it initialises for the first time.
I also created a new python module with the new API calls here: petsafe-api · PyPI
I noticed when I was sniffing out API calls from the PetSafe app that there are also some APIs for other petsafe products available, like GPS trackers. I don’t have any of the other products apart from the SmartDoor, but happy to take information and contributions on my documentation of the API here GitHub - ThomasHFWright/petsafe-api-documentation · GitHub to document what else is available. This repo has a postman collection you can load up to easily test out API calls.
You can also submit PRs or further info to the API itself here GitHub - ThomasHFWright/petsafe-api: Connect and control a PetSafe devices using the PetSafe API. · GitHub
Thanks!
