@haffle, did you get a Node-Red flow for pulling the data off your Powerwall?
@cbn1, if you have a spare Pi, then that is best for Node-Red. I’m not keen on mixing things on the emonPi; it can have unexpected consequences. (I changed the thread title).
@miker, did you get it to work, I presume so. - How to add a CA cert to access a powerwall? - #4 by miker
