Nextion wall mount

Hi there!

In this project I tried to create a simple(?) wall mount with quick and easy access to Home Assistant. The purpose is to have a remote controller, that's mounted on the wall and gives a quick info of the day ... or basically whatever you need from Home Assistant.

Update:

This repo is not maintained anymore, as I'm not using the screen. But I leave the code and resources here for anyone who is looking after ideas :)

Demo video HERE

Features:

Basically everything is connected to Home Assistant through Esphome:

1. Overview - General info:

  • Indoor / Outdoor temperature / Rain Forecast + Weather Symbol
  • Display Date and Time
  • My Facebook Birthay Calendar / Facebook Events / Google Calendar
  • Hi! - Automation (lights on, etc)
  • Bye! - Automation (music and lights off, etc)
  • Play/Pause Media player - Kodi in my case

2. Lights- The important ones:

  • Kitchen, Livingoom and Bedroom Lights toggle (Slider not implemented yet)

3. Media - Radio and quick controls:

  • 6 stations
  • Vol +/-
  • Play/Pause button

4. Vacuum Cleaner - Map:

  • Clean the place with zones
  • Vacuum Controls: play/pause, "TrashSpot", Go home, Set speed
  • Stream music on the vacuum

5. Automations - Switches:

  • Kitchen plug - for the coffee maker
  • Morning routine automation (lights on, music on at for ex. 6:45)
  • Wifi status
  • Secret menu - but of course
    • Change display brightness
    • Reboot the display
    • Initiate the screensaver (coding still needs to be done)

6. Screensaver

Other features:

  • Screen turns off after 1h standby time
  • Screen brightness is set based on sun elevation and devices connected to Wifi (group.all_devices)
  • Auto refresh every page and relevant variables initialize with correct state data (ex. if the lights are on, switch will turn to on)
  • Every registered touch gives a feedback on the buzzer

HW used:

  1. Home Assistant
  2. Wemos D1 mini - with Esphome
  3. Nextion Display - NX4832T035_011
    • Mine is actually TJC4832T035_011 but both are the same(?) HW
    • 3.5inch with a resolution of 480x320
    • Resistive touch
  4. A passive buzzer
  5. 3D printed case for the wall mount

Resources and SW:

You can find the used resources in the repo. Basically none the SW and HW is actually my work:

  • Icons were exported from Material Design Icons - Thanks!
  • The weather pictures were taken from Yr Weather Symbols repo - Thanks!
  • For Esphome: The basic descriptions from the site is really helpful.
    • A lot of code from various github repos served as a base, tailored to my setup.

Something very important:

This display board is not Nextion!

This is actually TJC. And the HMI file will not open in Nextion Editor -> only USART HMI editor. I'm not sure if the project can be ported either way, but essentially the 2 editors are the same (chinese vs english...)

I barely started this project, just for fun. As I'm no programmer, I still need to work on the coding, but the community comes in handy!
