boneIO Dimmer LED¶

Features¶

Powering Dimmer¶

To power up dimmer connect it to 12-24VDC

Connecting Ethernet¶

Connect Ethernet cable to LAN port in boneIO dimmer. With default configuration address would be obtained via DHCP.

Connecting LED strips¶

Mixing left and right side is not allowed!

Each side can measure power using INA219 sensor.

One channel can use up to 2A. Each side can load up to 10A.

Connecting White strip¶

Connecting RGBW strip¶

Connecting CCT strip¶

Connecting Inputs¶

The operation of digital inputs is based on applying GND of power supply to the IN_01 to IN_08 pin. Input is triggered when IN pin is connected with GND pin.

Switching light¶

binary_sensor:
  - platform: gpio
    name: 'IN_01'
    pin:
      pcf8574: pcf_inputs
      number: 1
      mode:
        input: true
      inverted: true
    on_press:
      - light.toggle: chl_01

Bright light with input button¶

Example how to rotate brightness of the light with one push button.

Add to IN_01 id and on_press option.

binary_sensor:
  - platform: gpio
    name: 'IN_01'
    id: in_01
    pin:
      pcf8574: pcf_inputs
      number: 1
      mode:
        input: true
      inverted: true
    on_press:
      then:
        - while:
            condition:
              binary_sensor.is_on: in_01
            then:
              - if:
                  condition:
                    lambda: 'return id(chl_01).current_values.get_brightness() >= 0.90f;'
                  then:
                    - light.control:
                        id: chl_01
                        brightness: 0%
                    - light.turn_off:
                        id: chl_01
                  else:
                    - light.dim_relative:
                        id: chl_01
                        relative_brightness: 5%
                        transition_length: 0.2s
              - delay: 200ms

Changing fuse¶

Open top cover and replace fuse in case it’s burned.

Software installation¶

Software installation procedure is same for boneIO ESP and boneIO Dimmer. Connect USB-C cable to your PC and choose Dimmer in web installer.

Follow instructions here: /docs/esphome/install2024_3

Dimmer specifics configuration is available at: Dimmer Esphome configuration

Technical data¶

Here are technical data, which are needed to configure software. In default software all data are already bundled in Esphome config, so you don’t need to worry about it.
