Python Baseboard Management Controller (BMC) for Intelligent Platform Management Interface (IPMI)
pypmi primarly extends pyghmi to provide a configurable and extensible low cost BMC solution to monitor and control chassis power and enable Serial-over-Lan (SoL) using IPMI 2.0 and commodity internet-of-things (IOT) and off-the-shelf hardware.
The PyPmb (Platform Management Bridge) allows for bridging up to 255 targets from a single IPMI address.
