Preinstallation Requirements

• A Telegram client (www.telegram.org)
• A Telegram bot
• Obtain chatID's for all Telegram recipiets you would like to receive messages

Installation and Configuration:

Obtain a Telegram client

• Go to the Apple store or Android Play store to install the client on your mobile and follow instructions

Create a Telegram Bot

• With your Telegram client start a conversation with @BotFather
• Send a message: /newbot
• Follow the on-screen instructions
• When choosing a name for your bot, ensure the name ends in "bot", e.g. MyAwesomePimaticBot
• After completing the required steps, BotFather will provide a token (similar to this: 784324329:EETRNJU3jQEGWQdjNv3llb4bnDSDREGuuuL)
• Make sure you copy this token, and keep it secret !

Obtain your chatID

• With your Telegram client start a conversation with the ID bot (@myidbot)
• send /getid
• The bot will respond with your ChatID, e.g. 315123987
• Take note of this number
• Repeat for each recipient you want to register in Pimatic

Install the Plugin (required for using the send telegram functions)

• Install Pimatic-Telegram via the frontend (preferred) and check if it has been activated.
• Add the API token in the designated field, and add recipients as required (Friendly name, chat ID, enabled flag)

Alternatively add it to the Plugin section of your config.json:

{
  "plugin": "telegram",
  "apiToken": "<bot api_token from previous step>",
  "active": true,
  "recipients": [
    {
      "name": "FriendlyName",
      "userChatId": "<user_id from previous step>",
      "enabled": true,
      "admin": false 
    }]
}

You can specify multiple recipients. Enabled should be set to true for a recipient to receive messages

• Check if the plugin has been activated. If not activate it
• Restart Pimatic

Install a Telegram Receiver device (required to send client requests to Pimatic, and enable the telegram received rule predicate)

• Define a new TelegramReceiverDevice via the frontend (preferred)
  • Make sure to change the default secret !
• To allow users to send requests to Pimatic, set their Admin flag to enabled in the frontend or in config.json

  "recipients": [
  {
    "name": "FriendlyName",
    "userChatId": "<user_id from previous step>",
    "enabled": true,
    "admin": true 
  }
  

• Restart Pimatic
• Send commands from Telegram to Pimatic, a good start is sending "help"

Alternatively add the device directly to the Devices section your config.json:

{
  "secret": "change_me_now!",
  "auth_timeout": 5,
  "id": "telegram-receiver",
  "name": "Telegram Receiver",
  "class": "TelegramReceiverDevice"
}

Known issues:

• "execute" cannot be used as a keyword, to prevent vulnerability exploitation. This is a security concern and will not likely be changed in the near future

FAQ

Please check the following first, as all similar issues have been solved so far by taking the below steps:

I have installed Pimatic-Telegram, but no messages are sent, and no errors are logged. Whats wrong?

• Has the plugin been activated? Check in the section "Install the Plugin"
• Have you activated the intended recipient? Or has the enabled check box accidentally not been checked?
• Restart Pimatic, this is often forgotten after the installation and or configuration.

I have installed Pimatic-Telegram, but I cannot send instructions to Pimatic

• Have you defined a TelegramReceiverDevice and configured appropriately?
• Have you set the admin flag for the recipient sending commands and is the recipient enabled?
• Have you restarted Pimatic after making these configuration changes?

If you took these troubleshooting steps, you have probably rebooted Pimatic twice, once after installation, and once after configuration changes
