Hi. This Petlibro feeder has been added to Tuya Local (GitHub - make-all/tuya-local: Local support for Tuya devices in Home Assistant) by the developer. It will let you use the manual feed, set the different controls available in the app, and has the sensors setup. You can do pretty much everything except view the camera and manage the scheduled feedings.
To use it you will want to:
- Remove the feeder from the Petlibro app (this will remove it from Petlibro and reset the device)
- Download the Tuya app to your phone. Setup an account within the phone app and add the device (the same way you did with the Petlibro app)
- Recreate the scheduled feedings in the phone app
- Create a free Tuya developer account so you can get the device id and local key (there are many tutorials/guides showing how to get a local Tuya key to use with Home Assistant)
- Install Tuya Local (I recommend using HACS, you can see the instructions on the link I provided above)
- When adding the feeder to Tuya Local, selecting protocol 3.4 works
Hope this helps!
