Telegram group chat invalid ID

Configuration
1

Hi there,

I am trying to set up a new telegram notification. Previously I had it working with the bot itself, but now I want to include it in a group so other people can see it too. Here is my configuration

telegram_bot:

  • platform: polling
    api_key: “7XXXXXXXXXXXXXXXXX4”
    allowed_chat_ids:
    • 2XXXXXXX9
    • -4XXXXXXXX0

notify:

  • platform: telegram
    name: “withgroup”
    chat_id: -4XXXXXXXX0
  • platform: telegram
    name: “withme”
    chat_id: 2XXXXXXX9

if I trigger

action: notify.withme
data:
message: not

I works perfect. However if I trigger:

action: notify.withgroup
data:
message: not

It doesn’t work and in the logs it shows:
homeassistant.exceptions.ServiceValidationError: Invalid chat IDs

Note that if I call the url https://api.telegram.org/bot7XXXXXXXXXXXXXXXXX4/sendMessage?chat_id=-4XXXXXXXX0&text=not
it works perfect so the chatId is correct.

Has anybody a clue of what may be going on?

You can try the following:

action: telegram_bot.send_message
data:
  message: test
  target:
    - "-4XXXXXXXX0"
