:description: Instructions for setting up switches that can remotely invalidate all ESPHome preferences stored in flash and reboot ESP.

|
|
|
|
The ``factory_reset`` switch allows you to remotely invalidate (reset) all ESPHome :ref:`preferences <preferences-flash_write_interval>` stored in flash memory and reboot your node.
|
|
After reboot all states, parameters and variables will be reinitialized with their default values. This is useful:
|
|
|
|
- for devices preflashed with ESPHome to reset behavior back to factory state
|
|
- in case of moving a device to a new environment or starting a new use-case (e.g. reset counters or state)
|
|
- for privacy concerns when giving away a device
|
|
|
|
.. note::
|
|
|
|
**USE WITH GREAT CAUTION!** All credentials, global variables, counters and saved states stored in non-volatile memory will be lost with no chance of recovering them.
|
|
Even raw reading of flash memory with ``esptool`` will not help, since data is physically erased from flash memory.
|
|
|
|
For devices configured using :doc:`captive portal </components/captive_portal>`, this will reset WiFi settings as well, thus making such devices offline.
|
|
You'll need to be in close proximity to your device to configure it again using a built-in WiFi access point and captive portal.
