Tuya Dimmer - Tasmota > ESPhome

ESPHome
1

Hello Community,

I have a tasmotized Tuya dimmer using TuyaConvert. I wanted to give ESPhome a shot. I installed the addon and compiled the following:

esphome:
  name: csmartdim
  platform: ESP8266
  board: esp01_1m

# Enable logging
logger:
  baud_rate: 0

# Enable Home Assistant API
api:

ota:
  password: "3793e165a8b72b0534fcb1676a2d6770"

wifi:
  ssid: "***"
  password: "***"

  # Enable fallback hotspot (captive portal) in case wifi connection fails
  ap:
    ssid: "Csmartdim Fallback Hotspot"
    password: "EATIN1f442vb"

captive_portal:

# My dimmer used the hardware serial port on the alternate pins
uart:
  rx_pin: GPIO13
  tx_pin: GPIO15
  baud_rate: 9600

# Register the Tuya MCU connection
tuya:

The validation gives:

I had some errors to migrate, but found out I had to downgrade my Tasmota version. Successfully migrated and added the device via ESPHome integration using the device IP.

My question is how to configure it? I have only only light switch in HA, but it doesn’t do any action on the device. The dimmer has on/off, increase and decrease button.

I followed the guide on Tuya Dimmer : Tuya Dimmer — ESPHome

It seems I needed to enable webserver to log to the device directly.
Can anyone provide some guidance please? Thank you.

Even with baud_rate set to 0 it still logs over wifi.

I get the following error:

Although pinging the device is successful, ESPhome cannot connect.
