Last summer we modified the EmonTH firmware to perform EMC calculations onboard before transmitting the values to our EmonCMS server. (EMC is the percentage of moisture content that wood stabilizes at when subjected to a certain environment for a long enough period of time) We later discovered that it will be difficult for other people to use our contribution because it requires flashing custom firmware and editing the config file. Additionally, our new data structure was incompatible with what has already been standardized from an EmonTH node. A better solution is to calculate an EMC value on the fly using a custom virtual feed. This thread will document the process to implement this solution, and will serve as the basis for other related projects.
