Lesson31- How to decode 433MHz RF signal and control RF device by ESPHome

[tfmeier]

I'm trying to setup my KC868-AG but can't learn the codes

Here's my ESPHome yaml file

```
esphome:
  name: kc868-a4
  friendly_name: "RF 433MHz Gateway"

esp32:
  board: esp32dev
  framework:
    type: arduino

# Enable logging
logger:

# Enable Home Assistant API
api:

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

captive_portal:

web_server:
  port: 80

remote_receiver:
  pin: 19
  dump: all
  tolerance: 50%
  filter: 250us
  idle: 4ms
  buffer_size: 2kb

remote_transmitter:
  pin: 21
  # RF uses a 100% carrier signal
  carrier_duty_percent: 100%

switch:
  - platform: template
    name: RF Power Button
    turn_on_action:
      - remote_transmitter.transmit_rc_switch_raw:
          code: '0101011111111101000000111'
          protocol: 1
          repeat:
            times: 2
            wait_time: 20ms
    turn_off_action:
      - remote_transmitter.transmit_rc_switch_raw:
          code: '0101011111111101000000111'
          protocol: 1
          repeat:
            times: 2
            wait_time: 20ms
```

Here's the log file
```

```

No log messages when pressing any button on the remote.

I have 2 remotes:
DD2702H | https://rollerhouses.com/products/dd2702...ooya-motor
MT02-0101-067008 | https://www.homeautomationandtubularmoto...101-050008

Looks like I'm missing something. One thing I noticed is the YT video shows a Home Assistant connected message I don't get.... Not sure what's this connection for.

Any idea why this is not working?
