With one of the two main energy metering nodes out of order, it’s becoming more urgent now to implement a replacement. It would be a shame to break the cycle, after some 8 years of data collection, all logged and waiting for future visualisation.
There are quite some signal sources, more than a simple JeeNode w/ ATmega328 can easily handle. Given the recent focus on STM32F103-based boards, it should come as no surprise that this has also been picked as base for the new node.
