Sonoff Switchman M5 as a smart switch for smart lights

ESPHome
1

Hi, I would like to use my Sonoff Switchman M5 as a smart switch for the yeelight lamp and not as a power cutter. Installed esphome, configuration as below, I searched the entire forum and google, however, I did not find any relevant clues on this topic.

esphome:
  name: switchman-entrance

esp32:
  board: esp32dev
  framework:
    type: arduino

# Enable logging
logger:

# Enable Home Assistant API
api:
  encryption:
    key: ""

ota:
  password: ""

wifi:
  ssid: !secret wifi_ssid
  password: !secret wifi_password

  # Enable fallback hotspot (captive portal) in case wifi connection fails
  ap:
    ssid: "Switchman-Entrance"
    password: ""

captive_portal:
    
output:

  - platform: gpio
    id: relay_1
    pin: 23
    
  - platform: gpio
    id: relay_2
    pin: 19
    
light:
  - platform: monochromatic
    output: pwm_output
    name: "LEDs"
  - platform: status_led
    name: "Swtich state"
    pin:
      number: 5
      inverted: true
    
  - platform: binary
    id: corridor_switch_1
    name: "Left Switch"
    output: relay_1
    
  - platform: binary
    id: corridor_switch_2
    name: "Right Switch"
    output: relay_2

    
binary_sensor:
  - platform: gpio
    id: left_button
    pin:
      number: 4
      mode: INPUT_PULLUP
    on_press:
      - light.toggle: corridor_switch_1
      
  - platform: gpio
    id: right_button
    pin:
      number: 15
      mode: INPUT_PULLUP
    on_press:
      - light.toggle: corridor_switch_2

What is your question?

I would guess how to detach buttons from leds, still be able to use buttons to trigger HA trigger for smart bulbs and ideally keep the led indicators for the on/off of the lights?

I think you can’t switch the leds separately. Flashing Tasmota on Sonoff SwitchMan - NotEnoughTech

This is an old topic but it deserves a correct answer.

Disconnecting the buttons from the relays is quite easy:

  • Remove the on_press: action frrom the binary sensor definition. That will disconnect the button from the relay. You can do it for any of the buttons or both, it’s completely your choice.
  • To make the button visible as an entity in Home Assistant, you need to add a name: attribute to the respective binary sensor definiton and give it some name.
  • The config file shown above already has correctly defined binary light entities so the relays are now controlled from the HA only.

I have created a config for the M5 with substitutions and conditions that suit my use case: esphome-configs/switchman-m5-1c.yaml at 775fcd83343ad97f4cfcca35a6431b007d533785 · velijv/esphome-configs · GitHub

substitutions:
  ...
  hass_device_1: light.ceiling

which is the virtual device from HA. And to check if API is connected, toggle this else toggle the relay:


binary_sensor:
  - platform: gpio
    name: Button
    id: ${device_name}_button
    pin:
      number: 0
      inverted: true
    on_click:
      then:
        if:
          condition:
            api.connected:
          then:
            - homeassistant.service:
                service: homeassistant.toggle
                data:
                  entity_id: $hass_device_1
            - light.toggle: ${device_name}_led_red
          else:
            - switch.toggle: ${device_name}_switch

Hi, I’m interested in the M5 and flashing it with ESPhome. Does this method give the ability to decouple the relay and reconnect to the relay manually? I would like to use the m5 with smart lights but have the backup option. Similar to what the Aqara switches do? Thanks.

yes, my code does this automatically - if wifi and api are connected, use the virtual device, if not, use the relay. you can create a template switch that you can manually toggle between the smartlights and relay.

Great, thank you. I’m new to smart switches, smart home etc. hope I can figure it out. I’ll confirm.

Hi Veli, I’m trying to apply this config but getting an invalid YAML Syntax. This is at light.toggle device_name led_red. Also, does this tell the red led to turn on and off with the light? What if I don’t want the red led on? Thanks.

It depends.
On M5 1-gang You can operate LED and Relay individually.
M5 2-gang: Left channel LED & Relay connected on motherboard, Right button - separately.
M5 3-gang: All channels LED’s & Relays wired together.

Pins etc. can check on https://devices.esphome.io/

ESPHome has had many updates, but I tried my old config on Github and it compiles for me with no error

Yes, just remove the line if you don’t want that.
