/Esphome-TTGO-T-Display-Weather

Primary LanguageC++

NOTE: The goal of this fork is to work towards fix TTGO Weather so it works w/ ESPHome 1.17-dev and also tidy it up a bit
NOTE #2: Image output is scrambled showing 3 grayscale ghosts instead of proper RGB565 (16-bits per pixel)
NOTE #3: To make this work with ESPHome stock, all pngs must be converted to RGB24 (24-bits per pixel), this increases the size of the binary such that not all images can be used; some weather condition icons have been conflated in ttgo_weather.yaml

Project Picture

Components:

Home Assistant entities:

  • Screen Backlight - switch for backlight
  • left_button - left onboard button on TTGO T-Display, turn off screen
  • right_button - right onboard button on TTGO T-Display, turn on screen

Setup under Hass.io

  • Open a terminal using either Terminal or VSCode addons
cd /config/esphome
git clone THIS_REPOSITORY_URI
cp -r Esphome-TTGO-T-Display-Weather/fonts .
cp -r Esphome-TTGO-T-Display-Weather/images .
# cp -r Esphome-TTGO-T-Display-Weather/custom_components/ . # Disabled using stock RGB24
echo '<<: !include Esphome-TTGO-T-Display-Weather/ttgo_weather.yaml' > ttgo_tdisplay_weather.yaml
  • edit Esphome-TTGO-T-Display-Weather/secrets.yaml using nano (terminal) or code (in a vscode shell)
  • Within the ESPHome addon UI compile ttgo_tdisplay_weather, download the binary and flash it onto your TTGO T-Display using esphomeflasher over a USB-C on a non-hassio machine (hassio does not passthrough USB to ESPHome Addon)
  • If wifi is configured correctly, the device should appear as discovered in the Configuration -> Integrations screen

Feeding Weather Data from HASSIO to ESPHome

In the sensors.yaml section of your HA instance you'll need to provide your own values for esphome_current_weather_condition, esphome_current_weather_location, esphome_current_weather_temperature, and esphome_current_weather_temperature_units

Here's an example of this from my configuration, I have a weather.toronto entity provided by the Environment Canada integration; your settings would need to come from your configuration's weather entity

- platform: template
  sensors:
    esphome_current_weather_condition:
      friendly_name: 'ESPHome Weather Condition'
      value_template: 
        '{{ states.weather.toronto.state }}'
    esphome_current_weather_location:
      friendly_name: 'ESPHome Weather Location'
      value_template: 
        '{{ states.weather.toronto.attributes.friendly_name }}'
    esphome_current_weather_temperature:
      friendly_name: 'ESPHome Weather Temperature'
      value_template: 
        '{{ states.weather.toronto.attributes.temperature | float }}'
    esphome_current_weather_temperature_units:
      friendly_name: 'ESPHome Weather Temperature Units'
      # TODO: is there a way to get this from HA's system_units setting?
      value_template: 
        '°C'

Usage

  • Change secrets.yaml file for WiFi, OTA and API credentials.
  • Apply ESPhome configuration
  • Register new device in Home Assistant.
  • Change and include sensors to the Home Assistant.
