These 3 options can be used to change between WiFi/Ethernet, enable or disable Bluetooth proxy and enable the optional CO2 module


  1. In Home Assistant, go to Settings → Devices & Services → ESPHome

  2. Click on your Pro device

  3. Find the Configuration entities:

    • Network Type - Select WiFi or Ethernet

    • CO2 Sensor - Enable or Disable

    • Bluetooth Proxy - Enable or Disable

  4. Set your desired options

  5. Click the Apply Update button

  6. Wait for the device to download and apply the changes (1-2 minutes)

  7. The device will restart with the new configuration

Before enabling Ethernet: Make sure you have an ethernet cable connected before applying the update, otherwise you'll lose connectivity and need to reflash via USB.

Switching to Ethernet/PoE

Ethernet with Power over Ethernet (PoE) is recommended for permanent installations - a single cable provides both power and reliable data.

To switch:

  1. Connect an ethernet cable from your PoE switch to the Pro

  2. Change Network Type to "Ethernet"

  3. Click Apply Update

  4. Once restarted, you can disconnect the USB-C power

Enabling the CO2 Sensor

If you have the optional CO2 module installed:

  1. Set CO2 Sensor to "Enabled"

  2. Click Apply Update

  3. After restart, CO2 entities will appear in Home Assistant

Enabling Bluetooth Proxy

Turn your Pro into a Bluetooth proxy to extend range for other BLE devices:

  1. Set Bluetooth Proxy to "Enabled"

  2. Click Apply Update

  3. Your Pro will now relay Bluetooth signals to Home Assistant

Bluetooth proxy adds some processing overhead. Only enable if you need extended Bluetooth range.

Recovering from Connection Loss

If you switch to Ethernet without a cable connected (or have other issues):

See Restore or Update your Pro to factory settings for detailed instructions.

Checking Current Settings

The current settings are shown as diagnostic entities:

  • Network Type - Shows WiFi or Ethernet

  • CO2 Sensor - Shows if CO2 features are enabled

  • Bluetooth Proxy - Shows if Bluetooth proxy is enabled

These show what's currently running, not what you've selected for the next update.
