ESPHome

Easy Start

1. Plug it in - give your FLIP_C3 6-60vdc* or USB-C power

2. Provision Wifi

   1. Check Home Assistant for notifications or new devices

      1. Enter Wifi Info - Uses bluetooth integration

   2. Alternately look for FLIP_C3 WiFi and use "GenericPassword"

      1. Wait for login window or go to 192.168.4.1

      2. Enter WiFi info

3. Check ESPHome dashboard for device to adopt

USB Recover

If you need to reinstall the base firmware, we've set up an easy installer on our main website. This will allow you to use Chrome or Edge to install it via a USB-C cable. Current versions cannot be connected via USB-C while powered via the buck converter.

You may need to hold the BOOT button as you connect the USB cable. Alternatively you can hold the BOOT button while you press and release the RESET button if the FLIP_C3 is already connected via USB-C. Hold the BOOT button for a couple seconds after the device is connected to your computer and then proceed with the installation above. Once complete, power cycle the FLIP-C3 with the RESET button or disconnecting and reconnecting the cable. You can also use this time to swap to a DC power source via the 2P spring connector.

Adopt In ESPHome

Once you've followed the steps to connect your FLIP_C3 to Wifi, you should see it in the ESPHome dashboard available to be adopted. Adopting into ESPHome will generate a base YAML that references our YAML file on Github as an external package with the following lines:

24.09 - Our config files were moved into a separate repo, please change your existing package URL to the following for the latest updates.

packages:
  vdbxio.FLIP-C3: github://vdbxio/esphome-configs/flip-c3.yaml

This includes references to all the basics of the hardware and more. This includes the onboard WS2812, the red status LED, the Boot Button on GPIO9 and I2C is defined at id: bus_a

You can add ESPHome YAML to the end of this to get started quickly.

YAML Reference

The following are snippets to properly interact with FLIP_C3 hardware in ESPHome

Direct reference to the YAML we ship with is available on Github:

We're still working on organizing and modularization. Feel free to help out. There's a lot more in there than referenced here.

Board Definition

If you like, you can easily start a blank ESPHome device based on the ESP32-C3 using esp32-c3-devkitm-1 board type. This is default in ESPHome for C3 based boards and we use chip level pin numbers on our silkscreen.

esphome:
  name: bare-minimum
  friendly_name: Bare Minimum

esp32:
  board: esp32-c3-devkitm-1
  framework:
    type: arduino

Boot Button

The BOOT button is available in software on GPIO9 after boot. If held during boot, FLIP_C3 will be put into bootloader/flash mode.

binary_sensor:
  - platform: gpio
    name: Boot Button
    pin: 
      number: 9
      inverted: True
      mode:
