I am a newbie to Openems, and I want to implement a simple edge device using c language on an embedded device,
I will be interfacing a meter. I have browsed the documentation checking for the
API’s needed for the edge device to send its channels’ data to the backend, but the documentation of the “API Backend” have only guided me to the source code, but it was not very clear for me for the data format and the interface.
My question is can you point me to the documentation for the edge-backend interface and data format ?
