Managed to get one of the DC power meters I got for the #microgrid at #cccamp19 to talk via its TTL port. For now just to my laptop, but next week hopefully also to an arduino to make it a #LoRaWAN power meter. Code's up on github: https://github.com/tiefpunkt/gc9x-reader/ #onethingaweek #altpwr https://t.co/ISo35wY1ja
