Ah ok, but I have 2 bowl , and a camera also
This looks like the Petkit FreshElement Solo, not the Mini. Does the hack work on this model too? It seems cheaper and easier to find than the mini. Or is that the one you had to wire to a Shelly ?
I have the “cheap” no name dual bowl wired to a shelly, and also the solo reflashed. I’ll rewire the “cheap” back as it came from factory and return it to order a second solo and also reflash it.
Both have working automations in HA.
Ah got it, thanks! So the Solo can be flashed without the need for an extra esp? Would you mind sharing any link or guidance on how to do that?
Yes yes, it can be reflashed without additional hardware. To be honest I picked 3 or 4 sources made a soup of them and their code to fit my needs.
I’m 2000km away from home, and I’ll fly back home next week.
I’ll try to not forget and get some photos to you and the community, as well the complete code I used.
In last instance I’ll try not forget to do some kind of tutorial on the second Solo. I wish I was half gifted as many of the people I see doing tutorials to us…

Thanks a lot and happy new year!
So, here I am. I just finished my second unit, it’s working wonderfully.
I’ll add some more photos.
This is not my code, and unfortunately I can’t give credit for it because it took me some days copying around and trying to make sense of it, frankensteining it together.

Hey thanks for this, to boot into flash mode did you just hold the reset button? I’m having some issues getting it into flash mode and recognized by esphome.
yes, indeed u need to reset to get in flash mode

With the newest model above, has anyone figured out a way to dispense less while still relying on the feed sensor? I would like more control than the minimum right now. I added a feed_cats_in_grams service that basically just runs the motor for 2000 ms like the original model from the OP but it doesn’t seem consistent. It does give out a lot less kibbles though.
Did anyone look into getting Petkit water fountains to do the same maybe? I can’t even find an information on what chip they use or any disassembly video, for that matter.
Answering myself here: Petkit Eversweet 3 Pro has Telink TLSR8258, essentially same device as in Mija thermometers. Alternative firmware does exist for the latter, these SoCs are definitely hackable: GitHub - pvvx/ATC_MiThermometer: Custom firmware for the Xiaomi Thermometers and Telink Flasher
I figured out the messaging protocol petkit has used to communicate between the ESP and the cortex M0. it seems like they have used a similar combination on many of their products actually. I havent figured out all the packet types or fields but Ive figured out enough of it to dispense food and blink leds or make beep sounds, detect the charger, detect if the door is shut or the food is running low. and to send commands and be sure they were received correctly. I’m working to replace the onboard esp8266 firmware directly now that we know its “language”. the cortex M0 firmware can stay as it is, their protocol is actually decently implemented.
@Sly.vester any update on that front? I wonder how much different is this feeder from the Solo model which has its ESPHome config complete? Petkit Fresh Element Solo Pet Feeder | devices.esphome.io
following up on the original post from @AndreyShpilevoy
thank you very much for your documentation getting the Fresh Element Feeder “HomeAssist-ified”! Worked on mine last week and it works perfectly well.
One hint: you may put the ESP Board into a heat shrink tube which would give you the option to just lay it on top of the base board which would eliminate the need for disassembling the lower unit. It will be hold in place and fits snugly under the grey cover. Did that for mine - no wireless connection issues (beside the usual low reception of the ESP) or thermal problems.
Greetings
Tom
(anybody has one Fresh Element as a spare parts feeder? I am searching for a motor with gearing which opens/closes the front door. Second one that I have was destroyed by my dog…)
