:description: Instructions for setting up the debug component in ESPHome
|
|
:image: bug-report.svg
|
|
|
|
The ``debug`` component can be used to debug problems with ESPHome. At startup, it prints
|
|
a bunch of useful information like reset reason, free heap size, ESPHome version and so on.
|
|
It also allows you to get the same information as a text sensor, and to monitor the state of the
|
|
ESP heap memory (free space, maximum free block size and fragmentation level) and the main-loop timing.

|
|
- Free heap size at startup
|
|
- Flash chip size, speed and mode
|
|

|
|
- Chip features (BLE / BT / WiFi_BGN / EMB_FLASH / ...)
|
|
- ESP-IDF version
|
|
- EFuse MAC
|
|
- Reset reason
|
|
- Wakeup reason
|
|
- ESP8266:
|
|
|
|

|
- SDK, Core & Boot versions
|
|
- Reset reason & information
|
|
|
|
Accepts these options:
|
|
|
|
- **name** (**Required**, string): The name of the sensor.
|
|
- All other options from :ref:`Text Sensor <config-text_sensor>`.
|
|
|
|
- **reset_reason** (*Optional*): Reports the last reboot reason in a human-readable form.
|
|
|
|
Accepts these options:
|
|
|
|
- **name** (**Required**, string): The name of the sensor.

Sensor
|
|
-------
|
|
Configuration variables:
|
|
|
|
- **free** (*Optional*): Reports the free heap size in bytes.
|
|
|
|
- **name** (**Required**, string): The name of the sensor.
|
|
- All other options from :ref:`Sensor <config-sensor>`.
|
|
|
|
- **fragmentation** (*Optional*): Reports the fragmentation metric of the heap
|
|
(0% is clean, more than ~50% is not harmless). Only available on ESP8266 with Arduino 2.5.2+.
|
|
|
|
- **name** (**Required**, string): The name of the sensor.
|
|
- All other options from :ref:`Sensor <config-sensor>`.
|
|
|
|
- **block** (*Optional*): Reports the largest contiguous free RAM block on the heap in bytes.
|
|
|
|
- **name** (**Required**, string): The name of the sensor.
|
|
- All other options from :ref:`Sensor <config-sensor>`.
|
|
|
|
- **loop_time** (*Optional*): Reports the longest time between successive iterations of the main loop.
|
|
|
|
- **name** (**Required**, string): The name of the sensor.
|
|
- All other options from :ref:`Sensor <config-sensor>`.
