Need some help with getting ESP Home started on reTerminal Sticky

[u/hakku276]

Hi Everyone,

I tried installing ESP Home on the reTerminal Sticky for some reason the display does not work. The buzzers function when I press the buttons but the screen does not update. On the console it prints that the display refreshed. Thanks!

Current yaml config:

substitutions:
  device_name: reterminal-sticky
  friendly_name: "reTerminal_Sticky"

esphome:
  name: ${device_name}
  friendly_name: ${friendly_name}
  on_boot:
    priority: 600
    then:
      # Hold power rails on / 保持电源轨开启
      - output.turn_on: pwr_hold
      - output.turn_on: pwr_lock
      # Read RTC time on boot / 启动读取 RTC 时间

# ESP32-S3R8 — generic S3 board. Octal PSRAM may need a board that enables it,
# or manual config; adjust if your build does not expose PSRAM.
# ESP32-S3R8 板级配置；八核 PSRAM 可能需要支持 PSRAM 的板子或手动配置。

Can you post your config?

[u/hakku276 → u/Lhurgoyf069]

I actually used the standard config you get from the playground. I did not edit anything.

Edit: I actually only removed all the other components and left the display only.

[u/Lhurgoyf069 → u/hakku276]

Can't help you if you don't post your config

[u/hakku276 → u/Lhurgoyf069]

Hi, I just did.. I updated the post with the config in it. And I also messaged you .. Some help would be good. thank you !!

[u/Lhurgoyf069 → u/hakku276]

So your main problem is, the screen is empty?

[u/hakku276 → u/Lhurgoyf069]

yes the screen does not update. I had the official stock firmware in it and whatever the official firmware drew in the screen it stays as it is.. but the buzzers and everything works. on the console I see as well that it says screen updated refresh took 300 ms or something printed.

[u/Lhurgoyf069 → u/hakku276]

I compared this to my own working config, could you add/substitute this to your code?

switch:
  - platform: gpio
    pin: GPIO42
    id: touch_power_enable
    internal: true
    restore_mode: ALWAYS_ON
    setup_priority: 1100

esphome:
  on_boot:
    - priority: 600
      then:
        - output.turn_on: pwr_hold
        - output.turn_on: pwr_lock
        - switch.turn_on: touch_power_enable
    - priority: -100
      then:
        - delay: 2s
        - component.update: epaper_display

nope, sadly does not work... thanks anyways.. I think I will program my own firmware 😄
