When we got a smart meter and solar panels I wanted to record this data. Along the way I added more sensors and I've extended the software

Goals

  1. Record (smart) meter data and graph it (now including: electricity smart meter via USB, PV via bluetooth, heat meter via machine vision, water meter via line sensor, temperature via EvoHome)
  2. Log data in generic, long-lasting format locally (i.e. no externally hosted solution)
  3. Robust
  4. Interactive graphs on smartphone (domoticz, plot.ly, Highcharts, dygraphs)
  5. Customisable graphs (like grafana)
  6. Cheap/low-power solution (i.e. no Intel NUC)
  7. Versatile wrt interfaces (e.g. bluetooth/wifi/GPIO/USB)
  8. Not used to control or actuate. For that I use COTS products that work and don't crash :p

I bought a TP-Link HS110 version 3.0 smart wi-fi plug for 30 EUR to read out power usage of some appliances. I have a Raspberry Pi 3B+ to connect this to running domoticz and influxdb/grafana to visualise the data.
