Just to say that the standard OEM solution of an emonTx and emonBase is wireless but does not use wi-fi and has no need for ethernet, except you will need some display device? If you only need two CTs then an emonpi might be sufficient?
But what monitoring do you want to do? That’s going to affect the requirements. Just instantaneous display? Or logging as well? How many things (currents, voltages, powers)? Display as numbers or graphs, alarms?
I need data logging ideally only kWh electricity i dont care about anything else- it would be great to have HH data for 6 months, but just a total consumption to date would suffice ie a kWh meter.
when reading the information for Emonpi it seemed to be saying communication was over the local wifi or ethernet cable- i must have got that wrong.
FYI it’s a small guest house in Ghana- has 10 double rooms, all of which has fans and lights. its main loads are 5 large chest fridges/freezers in the kitchen and Bar, and the computer lab in the community learning centre- 200A might be overkill but my guess is it will definitely go above 100A at some point
Normally, the emonPi expects to be on a local area network, and behaves as a server to interact with the user via a web page. I’m not a RPi expert, but I understand you can connect a keyboard, screen and mouse to use it as a normal computer.
It would be much more versatile and probably convenient solution if you could set up a local wired or WiFi network, then you could have the RPi next to the incomer and access the data on your office computer.
