improvement:

support set domain for your own server. old version only set server IP address by number. This verison can set by a server domain name for TCP and MQTT server, added DNS function.

Hi
I have H32L I connect it to home assistant : https://www.kincony.com/how-to-create-sw...stant.html
When I power on or off channel from switch terminal board  or wall push bottom it power on but the real status not update on home assistant  app is not changing the status in home assistant to on or off
i work whit node-red ,          , need help whit this

ESPHome configure for KC868-A8:

function list:
1. 8 relay output
2. 8 switch input trigger relay output by on_press action
3. monitor 2 channel analog input for DC
4. TEMP-1 port: 2 channel DS18B20 temperature sensor use by 1 ports, actually, you can connect multi DS18B20 by one wire.
5. TEMP-4 port: WS2812B LED strip for 1 meter (30 LEDs)
6. network by Ethernet cable

1. WS2812B LED strip connect with DS18B20 temperature's port. (it's GPIO13)
2. Sound detect connect with KC868-A4's (DC 0-5V) analog input port. Sound detect is a sensor convert sound to DC 0-5v output.
3. install arduino library "FastLED" online.

1. Creating a Telegram Bot

Open Telegram and follow the next steps to create a Telegram Bot. First, search for “botfather” and click the BotFather as shown below. Or open this link t.me/botfather in your smartphone.

2. The following window should open and you’ll be prompted to click the "start" button.

3. Type "/newbot" and follow the instructions to create your bot. Give it a name and username.

4. If your bot is successfully created, you’ll receive a message with a link to access the bot and the "bot token". Save the bot token because you’ll need it so that the ESP32/ESP8266 can interact with the bot.

5. Get Your Telegram User ID

a. In your Telegram account, search for “IDBot” or open this link t.me/myidbot in your smartphone.
b. Start a conversation with that bot and type /getid. You will get a reply back with your user ID. Save that user ID, because you’ll need it later in this tutorial.

6. Preparing Arduino IDE

a. download arduino library and source code: 
  KC868-A4-A8-Telegram.zip (Size: 75.98 KB / Downloads: 652)
b. install "Universal Telegram Bot Library" : Go to Sketch > Include Library > Add.ZIP Library...
c. install "ArduinoJson Library" :
  Go to Skech > Include Library > Manage Libraries.
  Search for “ArduinoJson”.
  Install the library.
d. open source code, replace ssid , password, CHAT_ID, BOTtoken for youself.
e. download firmware and test.

You need to get the apikey form the bot before using the API:

1. Add the phone number +34 644 56 55 18  into your Phone Contacts. (Name it it as you wish)

2. Send this message "I allow callmebot to send me messages" to the new Contact created (using WhatsApp of course)

3. Wait until you receive the message "API Activated for your phone number. Your APIKEY is 123123" from the bot. As this is still in beta testing, the activation can take up to 2 minutes.

4. The WhatsApp message from the bot will contain the apikey needed to send messages using the API.
You can send text messages using the API after receiving the confirmation.

Example:

How to send a WhatsApp text message

https://api.callmebot.com/whatsapp.php?phone=[phone_number]&text=[message]&apikey=[your_apikey]

[phone_number]: Is your phone number asociated to your WhatsApp including the country code. (Ex: +34 123 123 123).

[text]: Message to send (urlencoded). You can use this online converter to encode the message. (i.e. %20 for space, %0A for new lines). WhatsApp formatting characters are allowed (i.e "*" for bold, etc.). Check here how to include emoticons in the message.

[your_apikey]: The apikey that you received during the activation process (step 4-5 above)

Example:

https://api.callmebot.com/whatsapp.php?p...1234567890
If you have problems building the URL, you can try the Web Browser assistant to test the API.

As this API is in beta testing, the messages can be delayed up to 1 minute.
