I’m looking to monitor our import and PV generation, maybe other loads as well if there is the opportunity.
So I’m after advice on the best setup to do that.
The main consumer unit has the import meter and various loads that might be worth monitoring, water pump, immersion heater, garage.
Our SolarPV are located on a granny annex that has it’s own secondary consumer unit about 15-20 meters away.
There are a couple of two pair wires unterminated near each CU, I have no idea what they were for or the condition of them.
I’m guessing if I connect an emonPi in the secondary CU to monitor the generation, where there is power and data and an emonTX to the primary CU to monitor the import and other loads, it should work?
If so do I have to buy both units at the same time or can I get the Pi and add the TX later?
Is there a better way to do it?
