  1. Had some time today to add the battery charge/discharge info. Also moved things around a bit to make sense for me See updated Grafana JSON and new Solar Sketch with added battery charge discharge code. Power Monitor-1600266455741.json rev1_02_amps_volts_temp__hum_batdisscharge_charge.ino
  2. Sketch for the battery bank voltage meter. Still to add measuring amps in and out of the bank. batteryVoltage2020june22.ino
  3. Here is the sketch for the esp8266, should work with most arduino devices with a bit of tinkering. voltsampstemp_15_september2020_amps_volts_temp_working_rev1.ino
  4. No I tried that you end up needing to use vendor supplied software and in general they are not too accurate or limited in what you can do with them. I am an opensource fan and a habitual DIY junkie.
  5. The cheap gadget (esp8266+dth11+ads1115) that measures the solar voltage amps temperature and humidity. This is the mock-up so far, will be putting it into a nice enclosure with its own power-supply once the calibration is completed and design finalised.
  6. Full day running the new dashboard Asic miner started up at 500 watts to use up excess production as the battery bank started the day full, everything above 500watts was running into the battery bank. Now to setup some relays that will start and stop the miner automatically depending on the battery state of charge and available solar production.
  7. There you go. You would need to add some extra plugins to grafana for displaying the gauges. 1 - D3 Gauge 2 - Default Grafana Gauge Power Monitor-1600160263595.json
  8. Finally Got around to doing the full Power Monitor Dashboard last night Day 1 - Testing accuracy etc
  9. For the AC side (Eskom) sensor I currently use (they not in stock at the moment) https://www.pishop.co.za/store/rpiz_ct3v1-3-current-and-1-volt-30a-ac-adapter-for-raspberry-pi-zero?keyword=current&category_id=0 This sensor is more suited as you can measure up to 7 circuits with it - https://www.pishop.co.za/store/rpict7v1-30a-version2---7-ct---1voltage---master?keyword=current&category_id=0 You can use that with raspberry pi3/4 or pizero w ( I use a pi zero w for the eskom side) I tried a self made 9v ac but had no luck so just bought one to save/prevent all the smoke
  10. Thanks I thought it might be something like that, will have to go learn a bit more about how this stuff on the grid side works
  11. Hi there @Jaws its a custom raspberry pi zero setup with some custom voltage and current sensors feeding data into an influx database and then displayed using grafana
  12. Update: It was road works people damaged an underground feeder cable. Was just weird that there was still voltage (130v) thats why I though something weird was going on. So does this mean that they maybe just broke a single phase of the feeder cable link? Just trying to understand how it works
  13. Edited power meter to show lower eskom voltage range
  14. Hi there I have a power meter monitoring my eskom grid side and my solar side which measures amps frequency volts The power meter is showing 0 hz and the volts are the usual 230v EDIT: my bad, its the voltage thats down, measuring now with multimeter showing 130v energy save lights are working. low amp loads all seem to be working fine e.g. internet modem kettles led come on but takes more than an hour to get up to boiling temp. Microwave comes on, but not enough power to cook. Neighbours all having the exact same issue.
