T5-4C-86: Relays not toggling when pressing physical touch buttons (only vibration triggered)

[slarti123]

Description: I am currently using a Sonoff TX Ultimate (T5-4C-86, with 4 relays) configured with ESPHome. When I press any of the physical touch buttons on the device, the relays are not toggling as expected. Instead, each press only activates the vibration motor, regardless of which button is pressed.

However, when I control the relays through the Home Assistant GUI (e.g., switch.tx_ultimate_5_tx_ultimate_51_l1), the relays toggle correctly.

Steps to Reproduce:

1. Flash the Sonoff TX Ultimate device with the ESPHome configuration.
2. Press any of the four physical touch buttons on the device.
3. Observe that only the vibration motor is triggered, and the relays do not toggle.

Logs: Here is the ESPHome log output when I press each touch button from left to right:

[16:25:22][D][tx_ultimate_touch.on_press:477]: Touch Position: 1 / State: 2 [16:25:23][D][tx_ultimate_touch.on_release:487]: Release Position: 1 / State: 1 [16:25:24][D][tx_ultimate_touch.on_press:477]: Touch Position: 4 / State: 2 [16:25:24][D][tx_ultimate_touch.on_release:487]: Release Position: 4 / State: 1 [16:25:25][D][tx_ultimate_touch.on_press:477]: Touch Position: 6 / State: 2 [16:25:25][D][tx_ultimate_touch.on_release:487]: Release Position: 6 / State: 1 [16:25:26][D][tx_ultimate_touch.on_press:477]: Touch Position: 10 / State: 2 [16:25:26][D][tx_ultimate_touch.on_release:487]: Release Position: 10 / State: 1

The Home Assistant logbook shows the following:

TX Ultimate 51 Vibration switched on TX Ultimate 51 Vibration switched off

What I Expect:

• Pressing Touchfield 1 should toggle Relay 1.
• Each physical touch button should control its respective relay (Touchfield 1 for Relay 1, Touchfield 2 for Relay 2, etc.).

What Happens:

• Each button press only triggers the vibration motor, and none of the relays toggle.

Additional Information:

• When I toggle the relays via the Home Assistant GUI, they work as expected.
• I have tried modifying the YAML to explicitly map the touch positions to the relays using binary_sensor definitions, but the relays are still not toggling when the touch fields are pressed.

Request:

• Could you provide guidance on how to correctly map the touch fields to the relays?
• Is there a way to prevent the vibration motor from triggering with each touch and prioritize the relay toggling instead?

Thank you in advance for your help!

I guess I "solved" it myself. I'm far from an expert, so please let me know, if there are any mistakes.

To troubleshoot, I utilized the local configuration file and made adjustments to the YAML settings.

Changes Made YAML Configuration Updates:

• Touch Relay Configuration: Updated the togglerelay*_on_touch substitutions to ensure that the correct relays are toggled when the buttons are pressed.

substitutions: toggle_relay_1_on_touch: "true" # Enable Relay 1 on touch toggle_relay_2_on_touch: "false" # Disable Relay 2 on touch toggle_relay_3_on_touch: "false" # Disable Relay 3 on touch toggle_relay_4_on_touch: "false" # Disable Relay 4 on touch

• Touch Field Handler: The handle_release script was modified to correctly map touch positions to their respective relays.

- id: handle_release
    mode: restart
    parameters:
      pos: int
    then:
      - if:
          condition:
            lambda: "return ${relay_count}==4;" 
          then:
            - if:
                condition:
                  lambda: "return pos <= 2;"  # Touch Position 1 und 2
                then:
                  - binary_sensor.template.publish:
                      id: touchfield_1
                      state: ON
            - if:
                condition:
                  lambda: "return pos >= 3 && pos <= 4;"  # Touch Position 3 und 4
                then:
                  - binary_sensor.template.publish:
                      id: touchfield_2
                      state: ON
            - if:
                condition:
                  lambda: "return pos >= 6 && pos <= 7;"  # Touch Position 6 und 7
                then:
                  - binary_sensor.template.publish:
                      id: touchfield_3
                      state: ON
            - if:
                condition:
                  lambda: "return pos >= 9 && pos <= 10;"  # Touch Position 9 und 10
                then:
                  - binary_sensor.template.publish:
                      id: touchfield_4
                      state: ON

• Touchfield Definitions: Ensured that the binary sensors for each touch field are correctly defined to toggle the relays.

binary_sensor:

• platform: template name: "Touchfield 1" id: touchfield_1 on_press:

  • if: condition: lambda: "return ${toggle_relay_1_on_touch};" then:
    • switch.toggle: relay_1
  • delay: ${button_on_time}
  • binary_sensor.template.publish: id: touchfield_1 state: OFF
  • script.execute: refresh_led_default

• platform: template name: "Touchfield 2" id: touchfield_2 on_press:

  • if: condition: lambda: "return ${toggle_relay_2_on_touch};" then:
    • switch.toggle: relay_2
  • delay: ${button_on_time}
  • binary_sensor.template.publish: id: touchfield_2 state: OFF
  • script.execute: refresh_led_default

  Similar updates for Touchfield 3 and 4...

Hope, that helps
