Usage of Telegram Bot

Create a macro on your duet called pair_telegram_bot

The content of that file is:

M291 P"waiting for telegram bot ..." T60 ;indicate the telegram bot that we want to pair a new user

Execute the macro on your mobile to pair your telegram with your newly created bot. Wait for the telegram bot to take over. It will send you a start code to connect your telegram with your bot. After that, the bot creats a challenge code and showing you that challenge code again on your DWC. Press the link in the Messagebox and you are paired with your bot.

The following commands are currently supported:

/webcam - to create a 5 second webcam snippet

/unregister - to remove yourself from the paired user

/register <challenge> - to supply the provided challenge

/start - to start the challenge response auth
