puck to Home Assistant via ESPHome

Hi everyone
I am trying to find the most efficient way to get data from puck.js to ESPHome.
End goal is to get it into Home Assistant. I have other sensors running off ESPHome (ESP32), so makes sense to re-use it to get the data.
Any tips on the service data format? I am sending battery status of puck plus 3 extra pieces of info

Did you have any success with this? What device type/config are you using on ESPHome and the ESP32 to get the data in?

It's something I'm interested in doing myself so might be able to be some help.

Hi, sorry, just saw your reply.
I got it working OK. Maybe not the best way, but had to work around the things that I do understand and examples I found online =)

That's great - thanks for posting that ESPHome code. I hadn't seen any examples of that before so it's great to be able to see something complete.
