THIS IS A OPEN SOURCE PROJECT THERE ARE NO FEES
Here is what I did:
Install Firmware
- Connect display with your computer
- Flash the Firmware: Use Chrome Browser while you on the Nightly Build-Site Select âGuition ESP32-S3-4848S040â and Install
- Setting Up Wifi: Follow Instructions on the screen
Install HomeAssistant Components
- HACS: Install HACS if you havenât already
- MQTT: Install and setup Home Assistant Add-on: Mosquitto broker if you havenât already (OpenHasp and the Display communicate via MQTT)
- openHASP Custom Component: Install The OpenHASP Component from within HACS
Set up HomeAssistant
- Make sure your Display is running and reachable (Default setup shows with text âplateâ on the top left corner of the screen and a popup with the actual IP-Adress).
- Go to shown IP-Adress with browser goto: http://your_ip/config/mqtt and fill in mqtt credentials from step 2 (see above)
- Got to shown IP-Adress with browser goto: http://your_ip/edit delete the pre-defined
pages.jsonl
file (Optional, otherwise Display loads this during startup)
- Go to shown IP-Adress with browser goto: http://your_ip/config/gpio and add:
GPIO Output
PIN: 40 (May be different on other Displays)
TYPE: Power Relay
Groupe: None
Value: Normal
â I had issues with entity naming when I skipped this step
- SetUp your display within Homeassistant detailed information here and follow the example weâll edit the files later on. If everything works as aspected the display will be auto-discovered by OpenHASP-Component
- Add a HA-Template sensor in configuration.yaml and edit to your needs (May use http://gridcalculator.dk/ to calculate col and gutter values)
template:
- binary_sensor:
- name: Display settings
unique_id: 1b3a3dae-fd0c-4f47-9c8b-5b680478a977 # https://www.uuidgenerator.net/
state: "{{ now() }}"
attributes:
update_automation: "automation.update_display_data" # add a the automation entity_id from step 3 before
update_time: "80" # sending the config via mqtt needs some time to complete. This stops the automation from re.run before sending config is finished
display_w: "480"
display_h: "480"
grid_cols: "12" # increase for more resolution of object
grid_rows: "12" # increase for more resolution of object
grid_gutter: "8" # This looked nice for me
grid_margin: "4" # This looked nice for me
bg_color: "#000000"
primary_color: "#4193d5"
secondary_color: "#ee9f52"
accent_color: "#A175C4"
success_color: "#6cbe58"
warning_color: "#d67430"
error_color: "#e25628"
radius: "4"
- If youâre done you should have a working display which is integrated in Homeassistant and comunicates via MQTT as well as a New Template Sensor with the given attributes
- Further reading if everything worked as aspected
Customizing
OpenHASP is highly customizable. Every Object can be set pixel perfect. This means you have to define every Width/Height x-and y-position.
To get rid of this I wrote I simple Jinja-Template. So I set Up dimensions with a grid system instead of pixel values. EXAMPLE:
Get Postion and size like this
{% import 'openhasp.jinja' as grid %}
w = {{grid.w(1)}}
h = {{grid.h(1)}}
x = {{grid.x(1)}}
y = {{grid.y(1)}}
This Example generates the size (1x1) and coordinates ( 1st from left, 1ist from top) for the given display settings
Get colors like this
color = {% from 'openhasp.jinja' import color %}{{color('primary')}}
light_color = {% from 'openhasp.jinja' import color %}{{color('primary_light')}}
dark_color = {% from 'openhasp.jinja' import color %}{{color('primary_dark')}}
This Example generates Color Values. So if you want to change colors, just change the attribute of the Display settings sensor instead of changing the openhasp config
Try yourself
- In the folder âcustom_templatesâ add a new file:
