Hello, colleagues! I have a challenge to build energy monitoring system based on emoncms. Going ahead the forum i guessed that most suitable approach: to use JSON request to my server,running at Raspberrry PI.
My input data (3ph system):
1. Energy counter totalizer through Modbus TCP, Modbus RTU (RS-485) (continuously incrementing, already calculated in kWht*h)
2. Energy counter RMS: Pa, Pb, Pc, Ua, Ub, Uc, Ia, Ib, Ic
Questions:
1. How to flush data of totalizers (use FEEDS or INPUTS) , which kind of writing more suitable?
2. Does Emon will split continiously incrimenetig totalizer to day-month-year consumption? Which files or code should be affected in system?
3. RMS values i want record only, without any recalculation, to view archive trends afterwards
Is it possible to adopt EMONCMS to this puprpose, or it's better to build up own logging and visualization system?
I'll be regarding for any links to explanation how to make this
