More information on my full weather station setup can be found in the docs folder, a good starting point is the background document.
As more devices are being added to the supported devices, the structure of this repository has recently undergone some changes. Common configuration and repeated code is being migrated to includes and packages where appropriate.
The configurations here expect all network, api, web and portal configuration to be found in an include file named common_network.yaml in the same directory.
Additionally the following packages are now included in this repository:
packages/ha_sensors.yaml- sensors used by demo code from Home Assistantpackages/internal_sensors.yaml- internal sensors (uptime, wifi signal)packages/fonts.yaml- common fonts, colours and characters
The packages/fonts.yaml file utilises substitutions to abstract the unicode needed, these substitutions can be included along with your top level substitutions using an inline include:
e.g:
substitutions:
NODE: "Kitchen Display"
TEXT_TITLE: "CatsLair"
FONT_SIZE_CLOCK: "52"
FONT_SIZE_BIG: "30"
FONT_SIZE_ICONS: "60"
<<: !include includes/fonts_subs.yaml
These fonts substitutions require some font sizes to be defined in substitutions to allow easy transfer between different density displays demonstrated here.
I recently picked up an Sunton ESP32-2432S028; integrated ILI1934, Touchscreen and ESP32 all-in-one board as an easy way to deploy a second WX screen to the smart house.
See ESP32-2432S028 for more information on this device.
This device also contains an LDR for display brightness adjustment, for this you can define an adjustment value, the voltage range and utilise auto_dim.h.
The full ESPhome configuration, as used by my coffee table unit can be found at esp32-2432s028.yaml.
This device is now fully supported by this code.
Another new addition to my devkit collection is the ESP32-2424S012, using a different TFT and touchscreen controller than the above board.
See ESP32-2424S012 for more information on this device.
Support of this device is a work in progress.
- Touch screen is not currently working.
- Display is working, using a component that is included in this repository (forked and maintained for latest esphome).
- ESP32 (example uses a DOIT DevKit V1)
- ESPhome compatible 240x320 TFT Screen (example uses an Adafruit ILI1934 2.8" TFT Touchscreen)

Current conditions coded in the wx.yaml lambda function for the display convert OpenWeatherMap current conditions to a Material Iconset icon. This can easily be adapted for other current conditions reporting.
This list changes over time with changes to my environment; refer to the current packages/ha_sensors.yaml file for the latest definitions used in my sample code.
Create a new ESPhome device
esphome wizard devicename.yaml
Edit the newly created devicename.yaml file, firstly adding the include file from this repository:
esphome:
name: testscreen
includes:
- includes/display_functions.h
All sensors used in the demo code can be found in the packages/ha_sensors.yaml and packages/internal.yaml files.
Download the fonts used in my example; it expects to find them in the fonts/ directory:
- fonts/alarm-clock.ttf - Alarm Clock (https://www.dafont.com/alarm-clock.font)
- fonts/futura.ttf - Futura (https://freefontsfamily.com/futura-font-family-free/)
- fonts/mdi.ttf - Material Icons (https://fonts.google.com/icons)
- fonts/arial.ttf - Arial
Append the wx.yaml from this repository to your newly created ESPhome configuration.
- Add media player controls/summary.
- Add light/switch controls.
- Add alarm panel.
- Design a 3D Printed Case.
