Telegram Bot doc changes for pull request #7294: fix

Telegram Bot doc changes for pull request #7294: minimal clarification about disabling notifications for Telegram web users

Telegram Bot doc changes for pull request #7294: added new notification services (like in the `mediaplayer` component doc); added a description to how operates now the `notify.telegram` platform; changed service calls from `notify/telegram_bot` to `telegram_bot/EXPLICIT_NEW_SERVICE` in some of the yaml examples and in the appdaemon example.

Telegram Bot doc changes for pull request #7294: added `parse_mode` global config variable in webhooks and polling platforms; fixed links to /components/notify.telegram

Telegram Bot doc changes for pull request #7294: removed complex usage of telegram_bot services (moved to the telegram_bot doc); removed api_key from required params; removed multiple target feature (it can be done with the telegram_bot services or simply defining more than one notifier); added keyboard and inline_keyboard config vars to every type of notification.

Use Telegram on your mobile device to send messages or commands to your Home Assistant.
Use Telegram on your mobile or desktop device to send and receive messages or commands to/from your Home Assistant.
This component creates notification services to send, or edit previously sent, messages from a [Telegram Bot account](https://core.telegram.org/bots) configured either with the [polling](/_components/telegram_bot.polling.markdown) method or with the [webhooks](/_components/telegram_bot.webhooks.markdown) one, and trigger events when receiving messages.
A command looks like `/thecommand`
### {% linkable_title Notification services %}
Available services: `send_message`, `send_photo`, `send_document`, `send_location`, `edit_message`, `edit_replymarkup`, `edit_caption`, `answer_callback_query`.

### {% linkable_title `Telegram` notification platform %}
The [Telegram notification platform](/_components/notify.telegram.markdown) requires the `telegram_bot` component to work with, and it's designed to generate a customised shortcut (`notify.USERNAME`) to send notifications (messages, photos, documents and locations) to a particular `chat_id` with the old syntax, allowing backward compatibility.
The required yaml configuration now reduces to:
```yaml
notify:
- name: NOTIFIER_NAME
platform: telegram
chat_id: USER_CHAT_ID
```
### {% linkable_title Event triggering %}
A command looks like `/thecommand`, or `/othercommand with some args`.
When received by Home Assistant it will fire a `telegram_command` event on the event bus with the following `event_data`:
```yaml
command: "/thecommand"
@ -26,13 +146,34 @@ from_last: "<last name of the sender>"
user_id: "<id of the sender>"
```
Any other message not starting with `/` will be processed as simple text, firing a `telegram_text` event on the event bus with the following `event_data`:
```yaml
text: "some text received"
from_first: "<first name of the sender>"
from_last: "<last name of the sender>"
user_id: "<id of the sender>"
```
if the message is sent from a [press from an inline button](https://core.telegram.org/bots#inline-keyboards-and-on-the-fly-updating), for example, a callback query is received, and Home Assistant will fire a `telegram_callback` event with:
```yaml
data: "<data associated to action callback>"
message: <message origin of the action callback>
from_first: "<first name of the sender>"
from_last: "<last name of the sender>"
user_id: "<id of the sender>"
id: "<unique id of the callback>"
chat_instance: "<chat instance>"
```
### {% linkable_title Configuration samples %}

### {% linkable_title Sample automations with callback queries and inline keyboards %}
Quick example to show some of the callback capabilities of inline keyboards with a dumb automation consisting in a simple repeater of normal text that presents an inline keyboard with 3 buttons: 'EDIT', 'NO' and 'REMOVE BUTTON':
- Pressing 'EDIT' changes the sent message.
- Pressing 'NO' only shows a brief notification (answering the callback query).
- Pressing 'REMOVE BUTTON' changes the inline keyboard removing that button.
Text repeater:
```yaml
- alias: 'Telegram bot that repeats text'
hide_entity: true
trigger:
platform: event
event_type: telegram_text
action:
- service: telegram_bot.send_message
data_template:
title: '*Dumb automation*'
target: '{{ trigger.event.data.user_id }}'
message: 'You said: ``` {{ trigger.event.data.text }} ```'
disable_notification: true
inline_keyboard:
- '/edit,/NO'
- '/remove button'
```
Message editor:
```yaml
- alias: 'Telegram bot that edits the last sent message'
hide_entity: true
trigger:
platform: event
event_type: telegram_callback
event_data:
data: '/edit'
action:
- service: telegram_bot.answer_callback_query
data_template:
callback_query_id: '{{ trigger.event.data.id }}'
message: 'Editing the message!'
show_alert: true
- service: telegram_bot.edit_message
data_template:
message_id: '{{ trigger.event.data.message.message_id }}'
chat_id: '{{ trigger.event.data.user_id }}'
title: '*Message edit*'
inline_keyboard:
- '/edit,/NO'
- '/remove button'
message: >
Callback received from {{ trigger.event.data.from_first }}.
Message id: {{ trigger.event.data.message.message_id }}.
Data: ``` {{ trigger.event.data.data }} ```
```
Keyboard editor:
```yaml
- alias: 'Telegram bot that edits the keyboard'
hide_entity: true
trigger:
platform: event
event_type: telegram_callback
event_data:
data: '/remove button'
action:
- service: telegram_bot.answer_callback_query
data_template:
callback_query_id: '{{ trigger.event.data.id }}'
message: 'Callback received for editing the inline keyboard!'
- service: telegram_bot.edit_replymarkup
data_template:
message_id: 'last'
chat_id: '{{ trigger.event.data.user_id }}'
inline_keyboard:
- '/edit,/NO'
```
Only acknowledges the 'NO' answer:
```yaml
- alias: 'Telegram bot that simply acknowledges'
hide_entity: true
trigger:
platform: event
event_type: telegram_callback
event_data:
data: '/NO'
action:
- service: telegram_bot.answer_callback_query
data_template:
callback_query_id: '{{ trigger.event.data.id }}'
message: 'OK, you said no!'
```
For a more complex usage of the `telegram_bot` capabilities, using [AppDaemon](https://home-assistant.io/docs/ecosystem/appdaemon/tutorial/) is advised.
This is how the previous 4 automations would be through a simple AppDaemon app:
```python
import appdaemon.appapi as appapi
class TelegramBotEventListener(appapi.AppDaemon):
"""Event listener for Telegram bot events."""
def initialize(self):
"""Listen to Telegram Bot events of interest."""
self.listen_event(self.receive_telegram_text, 'telegram_text')
self.listen_event(self.receive_telegram_callback, 'telegram_callback')
def receive_telegram_text(self, event_id, payload_event, *args):
"""Text repeater."""
assert event_id == 'telegram_text'
user_id = payload_event['user_id']
msg = 'You said: ``` %s ```' % payload_event['text']
keyboard = ['/edit,/NO', '/remove button']
self.call_service('telegram_bot/send_message',
title='*Dumb automation*',
target=user_id,
message=msg,
disable_notification=True,
inline_keyboard=keyboard)
def receive_telegram_callback(self, event_id, payload_event, *args):

self.call_service('telegram_bot/answer_callback_query',
message='Editing the message!',
callback_query_id=callback_id,
show_alert=True)
# Edit the message origin of the callback query
msg_id = payload_event['message']['message_id']
user = payload_event['from_first']
title = '*Message edit*'
msg = 'Callback received from %s. Message id: %s. Data: ``` %s ```'
keyboard = ['/edit,/NO', '/remove button']
self.call_service('telegram_bot/edit_message',
chat_id=user_id,
message_id=msg_id,
title=title,
message=msg % (user, msg_id, data_callback),
inline_keyboard=keyboard)
elif data_callback == '/remove button': # Keyboard editor:
# Answer callback query
self.call_service('telegram_bot/answer_callback_query',
message='Callback received for editing the '
'inline keyboard!',
callback_query_id=callback_id)
# Edit the keyboard
new_keyboard = ['/edit,/NO']
self.call_service('telegram_bot/edit_replymarkup',
chat_id=user_id,
message_id='last',
inline_keyboard=new_keyboard)
