This is a fully comaptible Breakout Board for the OpenDTU Project. With the opendtu breakout board and the opendtu software, you can read out, control and process Hoymiles inverters. In addition, the current energy yield is shown directly on a display.
This PCB has been designed together with the developers and is fully compatible. New features will of course always be added immediately ;).
