Add Restart Button fails

ESPHome
1

I want to add a restart button according to https://esphome.io/components/button/restart.html to my Bluetooth Proxy ESP32.

Out of the box it only comes with a safe mode boot button.

YAML of the ESP:

...
button:
  - platform: restart
    name: Restart
    entity_category: diagnostic
    disabled_by_default: false
    icon: mdi:restart
    device_class: restart
...

Validation gives:

button:
- platform: safe_mode
  name: Safe Mode Boot
  entity_category: diagnostic
  disabled_by_default: false
  icon: mdi:restart-alert
  device_class: restart
- platform: restart
  name: Restart
  entity_category: diagnostic
  disabled_by_default: false
  icon: mdi:restart
  device_class: restart

INFO Configuration is valid!

But when trying to install (wirelessly), I get:

Linking /data/esp-bluetooth-proxy/.pioenvs/esp-bluetooth-proxy/firmware.elf
/data/cache/platformio/packages/[email protected]+2021r2-patch5/bin/../lib/gcc/xtensa-esp32-elf/8.4.0/../../../../xtensa-esp32-elf/bin/ld: /data/esp-bluetooth-proxy/.pioenvs/esp-bluetooth-proxy/src/main.o:(.literal._Z5setupv+0xbc): undefined reference to `vtable for esphome::restart::RestartButton'

As a complete ESPHome amateur, let me guess: the ESP itself does not support the restart button, maybe? It’s a Lolin32 Lite ESP32.

Try to make a clean build and deploy. If you are adding new dependencies, it is my go to solution.

  • clean build files
  • validate if you haven’t
  • install

So you mean… this order?

I only added the button definition for the restart button.

Yes, and this would take less than 10 minutes and not harmful. Give it a try

Did so already few minutes ago, worked. File cleanup seems to be a good first try whenever installing fails in the first place. Thanks.

Button component was not there in the previous build, so this is a new component and it requires clean build. If you just change/modify existing components, you can just install which will hse previous artifacts rather than building everything from stratch.

Clean and install takes much more time than just install.

Understood. Compiling takes some time indeed, system is not the fastest one. I built my “standard set” of interesting buttons and sensors now, even if I tend to disable some of them in the end in HA.

button:
  - platform: restart
    name: Restart
    entity_category: diagnostic
    disabled_by_default: false
    icon: mdi:restart
    device_class: restart
sensor:
  - platform: uptime
    name: Uptime
    update_interval: 60s
    entity_category: diagnostic
    disabled_by_default: false
    icon: mdi:clock
    unit_of_measurement: s
    state_class: total
  - platform: wifi_signal
    name: "WiFi RSSI"
    update_interval: 60s
    entity_category: diagnostic
    disabled_by_default: false
    icon: mdi:signal-variant
    unit_of_measurement: dBm
    state_class: measurement
  - platform: internal_temperature
    name: "Internal Temperature"
    update_interval: 60s
    entity_category: diagnostic
    disabled_by_default: false
    unit_of_measurement: °C
    state_class: measurement
    device_class: temperature

…where this has been there as default already:

button:
- platform: safe_mode
  name: Safe Mode Boot
  entity_category: diagnostic
  disabled_by_default: false
  icon: mdi:restart-alert
  device_class: restart
