You can receive any form of a file with the Telegram trigger. To send a file from the OPC Router to Telegram, you need the Telegram Transfer Object. To send a file to the OPC Router, e.g. an image, you have to enter the trigger command as description. However, the file name of the image is not sent and you have to give the file a new name if you want to save the file.

In our small example the boiler temperature is queried. The data is collected by the OPC router and can be queried via telegram.

To display the boiler temperature on a remote web-enabled device, proceed as follows:

1. Go to the link of your bot that you received together with the AccessToken from BotFather.
2. Enter the command /start.
3. If you click on /help, the BotFather gives you all possible commands.
4. Select the command /BoilerTemperature.
5. The boiler temperature and the help text will then be displayed on your device.
