This project uses an ESP8266 with attached LCD-Display to connect to the local API of the Tesla Powerwall (V2). It is displaying all the current power flows (grid, home, solar, battery) and the SOC (state of charge).
A picture says more than a thousand words!
(This is the main screen.)
- Main screen includes:
- SOC (state of charge)
- Four different power flows (grid, home, solar, battery)
- Power flows are formatted in an organized manner. No overlapping will happen, units of values are converted to properly fit and look nice. :-)
- Indicator (dot in upper right corner) for the current API request status
For more information on all the different screens have a look at this wiki-page.
- You can find a quick start guide and documentation in the wiki. Have fun there!
- If you want to know, how the display shows the current data from the Powerwall check out this Wiki-Page. Enjoy exploring!
