I struggled a little bit when configuring the telegram action
The simple reason was that the chatID are prefixed with a “-”.
I also use node-red and the telegram node doesn’t require the “-” in front of the chat ID
so as far as I was concerned I did it right but OH log was throwing out HTTP 400 errors
After a bit of trying to type the token by hand and other things, I put the “-” in front of the chat ID.
Could this be added to the documentation "Make sure to include the “-” if your chatID is prefixed with a “-”.
