How to get data from a JK BMS
Does anyone have experience with getting data from a (Jikong) JK BMS into SignalK? Either by bt, can or rs485. Maybe via a SensESP?

engine RPM with pigpio library (edit: forget about pigpio)
Need help with an idea.
The idea is to get engine RPM data into SignalK via a python script and the pigpio library.

The raw signal comes from the alternator and the script already has functionality to multiply to get from pulses to RPM and also for averaging. A piece of hardware is needed to connect to a GPIO pin, preferably using an opto.
I’ve got it working on my Pi which is also running SignalK-server, outputting a number. Where I’m stuck is with not knowing how to tie these two pieces together.
Edit: the use of pigpiod made the Pi reboot within a minute. No error or logging at all. I continued with writing my own solution (read: copy/paste snippets from the internet)
