PLAF103 comaptibility?

[scholzri]

Hey there,
thank you very much for your work, I recently flashed a plwf105 with the firmware you provided, and it integrates flawlessly into homeassistant. Now, I contemplate about purchasing a petlibro feeder to complement my water fountain. Do you know if the most recent version of plaf103 would be compatible with esphome? Or is it just the plaf108?

I hope someone can answer my question.
Thanks in advance!

Hi,

I bought two feeders the 108 and the 103. The 108 is not using an esp chip but instead a RTL chip. I can’t remember the exact one. It’s a Tuya device and works reasonably with Tuya local. Except for the camera. I think it can be flashed since I think esphome supports rtl chips. But I have not attempted. If I ever open it back up I’ll post more details.

I got https://www.amazon.com/gp/product/B0BSFKGRBL/ which is PLAF107 also claimed to be ESP, I wonder if parts of the configs from this repo are compatible...

Sorry, I don't know without access to the hardware. If you connect to TX and RX and look at the logs (if any) it might give some clues. I remember that the serial logs basically told me exactly which pin was which.

If it is indeed an ESP chip flashing esphome I think should be trivial. It's just a matter of working out all the functionality

I popped my PLAF103 open to try and contribute to this, but it has a Tuya WBR3D with MCU RTL8720DN. Looking around it seems that that chip is "Unsupported" on https://github.com/libretiny-eu/libretiny which most point to for Tuya chips that aren't just ESP. In my interpretation of "Unsupported" it could mean that it could potentially be flashed to add ESPHome but would not be a good experience and at least for me sadly not worth the hassle, currently. Luckily there is a bounty for it, but at least no github updates (looks like most of the discussion is on their Discord) libretiny-eu/libretiny#1

Edit: Also if anyone else wants to crack the PLAF103 open be sure to have a 5+in long phillips screwdriver handy, and be careful lifting the mid section as my wires were hot glued into the socket.

Edit 2: My PLAF103 is actually an "Older model" that required the Petlibro-Lite app, I saw some people say new purchases don't have that as it's a different chip which I could get from support for $55. I'm probably not going to go that route, and instead try getting a PLAF203 during a sale so I can also see about adding the camera functionality in, but that does mean some PLAF103 may work, some may not and only way to check is either by seeing which app they work with or opening it up.
