Guide

We are going to install the latest firmware on the Everything Presence Lite, connect it to WiFi and then connect it to Home Assistant using the USB-C port.

Prepare

Using the included USB-A to USB-C cable, plug your Everything Presence Lite in to a laptop or desktop running Windows, MacOS or Linux.

MacOS users with M-series processors may not have required drivers installed by default and may need additional installation.

Installing the Firmware

Using the firmware selector below, select the options you would like to use with your Everything Presence Lite to customise your firmware. If you would like to use the recommended settings, select LD2450, No Module (select CO2 if you have the optional CO2 module) and standard.

Once you’ve made your choice, the connect button will appear. Hit the connect button, select the USB port form the list (should show as something like “USB Serial”).

Then hit Install Everything Presence Lite. This process should take around 2 minutes to complete.

If you do not see a connect button after customising the firmware, make sure you are using a browser that supports the Web Serial feature like Chrome, Edge or another Chromium based browser.

Connecting to WiFi

After the firmware has finished being installed, you will be prompted for WiFi details:

  1. Select your WiFi SSID from the dropdown (select Manual if it doesn’t appear)

  2. Enter the WiFi password

  3. Hit connect

Connecting to Home Assistant

  1. Unplug the device from your computer/laptop and you can now plug it in to a power adapter in the location that you want to use it permanently in.

  2. You should see a flashing red light, indicating that the device is on.

  3. Open the Home Assistant app on your mobile device and navigate to Settings → Devices & Services.

  4. Look for a new device labelled ‘everything-presence-lite-xxxxxx’ (ESPHome) and tap Add.

  5. Wait a few seconds, assign it to an area and then press finish.

We don’t recommend renaming the device at this point if you want to use the Everything Presence Zone Configurator tool, keep the default name to maintain compatibility.
