M5-energyUse

A companion app for smartMeterLogger-esp32. Does not function without a connection to the logger device!

M5-energyUse is an app that shows your current electricity and total energy use for today.

You will need smartMeterLogger-esp32 connected to your smartmeter to be able to use this app. SmartMeterLogger acts as a serial to websocket bridge and this app connects to the logger to get the energy use data.

Runs on

• M5Stack Grey

In real life the blooming on the TTGO-TM-ESP32 is not as bad as on the image.

The 3d printed case for the TTGO board by Jekyll555 fits quite nice and can be found on Thingiverse: https://www.thingiverse.com/thing:3672585

Setup

Open wifisetup.h and

• Set your WiFi credentials.
• Set WS_BRIDGE_HOST to the IP address of your SmartMeterLogger.
• You can set a static IP address by changing SET_STATIC_IP from true to false. If you set this you will also have to set your desired static IP, the gateway address, the subnet and at least one DNS server.
• Set NTP_POOL and TIMEZONE to the desired settings.

Now open M5-energyUse.ino and

• Set the #define on line 1 to LGFX_TTGO_TM for the TTGO-TM-ESP32 board and to LGFX_AUTODETECT for everything else.

Compile and flash the app to your M5Stack. M5-energyUse should now be able to use your logger to get the data.
