Main information screen

This is the screen you will see most of the time. What you can see:

• State of Charge (SOC for short) in the top row. This shows how much percent the powerwall is currently charged.
• The four power flow values in the lower two rows. There are grid, home, solar and battery. This shows how much energy is flowing currently.
  • Some values might be negative, but you might be supplying or obtaining power from/to the grid. The same goes for battery power.
    
  • The code is requesting the raw values from the Powerwall API and doesn't do any correction (e.g. you might have -30W solar power in the night).
  • If some power flow is greater than ±10kW there will be unit conversion from W to kW.
• An API request indicator is displayed in the upper right corner. More information in the next section.

API request indicator:

Welcome screen

This screen is displayed right after you supply power to the ESP8266. To make you happy, it shows you the great welcome message "Monitor Power". 👾

Connecting wifi screen

Connecting:

This screen is shown while the ESP is trying to connect to your WiFi network.

WiFi connection success:

After the "Connecting" screen this will be shown if your provided credentials were correct and the device successfully connected to WiFi.

WiFi connection failed:

This would be the second option you would be prompted with. The device could not connect to your WiFi network after trying to connect repeatedly for about 30 seconds.

Part 1:

Part 2:

Please follow what the device tells you to do. Please reboot the device by disconnecting and reconnecting the USB connection (or other 5V power source). Check the configured WiFi credentials, make sure that that WiFi is currently turned on and the WiFi network is reachable.

WiFi client details screen

If the connection could be established successfully, you will see this screen. Here you can see the hostname (device name in your router) and the IP address the ESP got via DHCP from your router.
