This is a pyramid extension. It starts up a thread that periodically queries the MorningStar TriStar MPPT for voltage and current values. It publishes these on the mqtt bus.

This is meant to plug into ib.bluelantern, but you can run it standalone. It depends on pymodbus, but that will be installed automatically by pip. Note that because pymodbus depends on Twisted, you need to have a C compiler and the relevant headers installed. Twisted is not used however, so you may customise setup.py in pymodbus and remove this dependency.

Add lines similar to below to your development.ini file.

pyramid.includes =

morningstar.instance = battery01
morningstar.name = mppt
morningstar.port = /dev/serial/by-id/usb-Prolific_Technology_Inc._USB-Serial_Controller_D-if00-port0
