Telegram

The telegram platform uses Telegram to deliver notifications from Home Assistant to your Android device, your Windows phone, or your iOS device.

The requirements are:

You need a Telegram bot. Please follow those instructions to create one and get the token for your bot. Keep in mind that bots are not allowed to contact users. You need to make the first contact with your user. Meaning that you need to send a message to the bot from your user.
You need to configure a Telegram bot in Home Assistant and define there your API key and the allowed chat ids to interact with.
The chat_id of an allowed user.

To retrieve your chat_id, contact any of the Telegram bots created for this purpose (@myidbot, @get_id_bot)

The quickest way to retrieve your chat_id is visiting https://api.telegram.org/botYOUR_API_TOKEN/getUpdates or to use $ curl -X GET https://api.telegram.org/botYOUR_API_TOKEN/getUpdates. Replace YOUR_API_TOKEN with your actual token.

The result set will include your chat ID as id in the from section:

{
	"ok": true,
	"result": [{
		"update_id": 254199982,
		"message": {
			"message_id": 27,
			"from": {
				"id": 123456789,
				"first_name": "YOUR_FIRST_NAME YOUR_NICK_NAME",
				"last_name": "YOUR_LAST_NAME",
				"username": "YOUR_NICK_NAME"
			},
			"chat": {
				"id": 123456789,
				"first_name": "YOUR_FIRST_NAME YOUR_NICK_NAME",
				"last_name": "YOUR_LAST_NAME",
				"username": "YOUR_NICK_NAME",
				"type": "private"
			},
			"date": 1678292650,
			"text": "test"
		}
	}]
}

Another way to get your chat ID directly is described below. Start your Python interpreter from the command-line:

$ python3
>>> import telegram
>>> bot = telegram.Bot(token='YOUR_API_TOKEN')
>>> chat_id = bot.getUpdates()[-1].message.chat_id
>>> print(chat_id)
123456789
