Two tools to measure power usage using external meters, and publish this in Prometheus format.
Both tools require libh2o-evloop. Compiling requires cmake.
Clone this repo like this: git clone --recursive https://github.com/berthubert/powmon.git
If you forgot the --recursive, it won't work.
To compile:
mkdir build
cd build
cmake ..
make
Requires libcurl-dev
Initializes /dev/ttyUSB0 to 115200 and expects to find DSMR coded data there. Published on 0.0.0.0:10000/metrics/
Requires libgpiod-dev
This tool counts transitions on a selected GPIO chip and pin.
solcount ./gpiochip0 3 works for me.
