New here, and wanted some pointers on setting up monitoring/data logging system for my electricity meter (rs485 output) and my windows 10 laptop… Just want the basic data (kwh usage throughout the days/weeks) to be sent to my pc for easy analysis. Is there any recommended free software out there to help me do this?
I have one of the USB adapters @Bill.Thomson pointed to (from China IIRC) plugged into an OrangePi talking to a MHRV via a Python script. Assuming you don’t want your laptop tied to a plugged in adapter hardwired into your meter, you might be better looking at a Pi based solution possibly via Node-Red and pass the data to EmonCMS via HTTP or MQTT.
cool, thanks for link…
Actually was planning on tying up the old laptop to this one job. Not quite ready to dive into raspberry pi and learning python, although it does seem pretty cool… its a time thing for me at the moment.
