A while back I reverse-engineered the Outback MATE protocol and made a Python library for emulating a MATE, and set it up collecting data from the family Holiday House. Then I found an open-source library called Grafana, and was finally able to put the data to use!

pyMATE is a python library that can be used to emulate an Outback MATE unit, and talk to any supported Outback device such as an MX charge controller, an FX inverter, a FlexNET DC monitor, or a hub with multiple devices attached to it.
