Assuming you've done a cursory Google search on modding these things and came up dry, I might start by physically opening up the case and seeing if there's anything recognizable inside. With luck, there may just be a straight up Pi board in there, although it could also be a custom board with a compute module or something else entirely
Home Automation
Discussion about general home automation ideas and projects, home automation protocols like Z-wave, Zigbee, Matter, etc, and home automation software and hubs like HomeSeer, Home Assistant, OpenHAB, Homey.
Correct assumption yeah, the product is unfortunately not very widespread, so there isn't much about it, let alone about jailbreaking it.
Physically opening and checking it sounds indeed like the next step, I was hoping to get a more definite answer from someone who was there before, but i guess that will have to be me.
For future users stumbling upon this:
I have investigated further, and it is indeed a raspberry pi-like board.
It comes with its OS on a microSD, so it's very easy to tinker without risking much.
I have been able to boot raspbian for Pi Zero 2 W on it, and i'm now testing with a home assistant install.
Update 2: Home assistant from the normal raspberry pi SD flasher worked like a charm out of the box.
It's basically just a custom raspberry pi board with some integrated antennas and apparently a temperature and humidity sensor included.
That's it, everything else went fine too, overall a strong purchase.
This seems very interesting. But I have never worked with raspberry, can you plesse help me a bit more wirh some steps how to get started to transform my Heart to a HA raspberryPi please🙏
