Garage door opener DY-CK400A

Hardware

Hi, I uploaded Tasmot to the garage module, but nowhere can I see the Tasmot settings for the module. Type DY-CK400A / board 8266 TYWE1S /
Tasmota only works error setting correctly. Please help with setting up Tasmota.
well thank you

Tasmota devices have a web page. That’s where the settings are.

I did not find this model on the Tasmot website

No, once you flashed it, open the web interface of the device.

Hi, I would like to flash the same device with Tasmota. Do you have the bin file with the template for this garage opener?

I have the same device, I successfully flashed ESPHome on it:

packages:
  common: !include common.yaml

esphome:
  project:
    name: Tuya.DY-CK400A
    version: "1.0"

esp8266:
  board: esp_wroom_02

uart:
  rx_pin: GPIO13
  tx_pin: GPIO15
  baud_rate: 9600

tuya:
  ignore_mcu_update_on_datapoints:
    # useless information
    - 1

globals:
  # https://github.com/esphome/issues/issues/6503
  - id: initial_state
    type: bool
    restore_value: no
    initial_value: 'true'

binary_sensor:
  - platform: tuya
    id: contact
    sensor_datapoint: 101
    on_state: 
      if:
        condition:
          lambda: 'return id(initial_state);'
        then:
          lambda: 'id(initial_state) = false;'

  - platform: template
    id: cover_state
    lambda: 'return id(initial_state) || id(contact).state;'

switch:
  - platform: tuya
    id: relay
    switch_datapoint: 1

cover:
  - platform: template
    device_class: garage
    name: ""
    lambda: 'return id(cover_state).state ? COVER_OPEN : COVER_CLOSED;'
    open_action:
      if:
        condition:
          lambda: 'return !id(cover_state).state;'
        then:
          # crazy stuff but this is how the relay works
          if:
            condition:
              lambda: 'return id(contact).state;'
            then:
              switch.turn_on: relay
            else:
              switch.turn_off: relay
    close_action:
      if:
        condition:
          lambda: 'return id(cover_state).state;'
        then:
          if:
            condition:
              lambda: 'return id(contact).state;'
            then:
              switch.turn_on: relay
            else:
              switch.turn_off: relay

Unfortunately, it has an issue: the sensor will not report its real state on initialization: Tuya MCU: `Initialization failed. Current init_state: 4` · Issue #6503 · esphome/issues · GitHub.

Otherwise works great. But if I knew this device used a Tuya MCU (meaning ESPHome cannot do much with it), I’d probably have sticked with Tuya Local.
