Werk-in-uitvoering!!!
Waarom?
De bedoeling is om een 230V AC middels software te kunnen aan/uitzetten. In principe kunt je dit gebruiken waar je AC stroom willen aan/uitzetten en meten. Het functioneert in principe dezelfde als een Sonoff POW switch.
Hoe werkt het
Wanneer IO-pin HIGH op de ESP32 gaat de voeding aan, aangestuurd door Octoprint, vlak voor starten met printen.

Questions
What parts does the StroomMeterACS712 use?
22 parts, built around the WEMOS D1 MINI, PCF8574AP, BC547 and WS2812. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the StroomMeterACS712 KiCad files?
From the pappavis/StroomMeterACS712 repository on GitHub, at the commit this page was made from: the board is PCBs/StroomMeterACS712.kicad_pcb and its schematic PCBs/StroomMeterACS712.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the StroomMeterACS712 design in my own project?
Its repository states no licence, so its author keeps all rights: ask pappavis before reusing the design.
