How to check your firmware version, update your device, and find release notes.

Checking Your Current Firmware Version

Home Assistant

  1. Go to Settings → Devices & Services → ESPHome

  2. Click on your EP1, EPL, or Pro device

  3. Look for the ESPHome Version entity (may be under "Entities not shown")

The version number follows the format YYYY.MM.DD (e.g., 2024.11.28).

ESPHome Dashboard

If you have ESPHome Dashboard installed:

  1. Open the ESPHome Dashboard

  2. Find your device in the list

  3. The current version is shown under the device name

How to Update Firmware

There are two methods to update your EP1, EPL, or Pro firmware:

USB Flashing

Use this method if:

  • OTA update fails

  • Device won't connect to WiFi

  • You need to do a factory reset

  1. Connect your device to your computer via USB-C

  2. Visit the firmware page:

    1. Everything Presence Lite: Restore or Update your EPL to factory settings using a computer

    2. Everything Presence One: Restore or Update your EP1 to factory settings using a computer

    3. Everything Presence Pro: Restore or Update your Pro to factory settings using a computer

  3. Click Install

  4. Choose Connect via USB

  5. Select the COM port for your device

  6. Follow the on-screen instructions

USB flashing will erase your WiFi settings. You'll need to reconfigure the device after flashing.
