Help - Python Program to Send Error Messages via Slack

Technical Questions Robot Communication
1

Hi,

I am new to the forums but am looking for some assistance as I am very new to python and raspberry pi equipment. I am trying to write a program that will read an input from my UR3 and send a slack message as a bot to all of the employees at our facility to tell them to come reset the robot. I have a Rasp 3+ and a solid state relay to run from the robots output. I need to just read an input on the GPIO and have the change in state trigger a message post. Seems simple enough but there are a lot of functions I am still new to so I am not sure how to write it. If anyone has any ideas of functionality that would help with a solution, it would be greatly appreciated. My goal is to decrease downtime from bad material that the robot is running in the cell.

Thanks,
Tripp

Hi @thudson,

The part of the application you are asking for assistance with doesn’t really have anything to do with the UR system. You would probably be better off trying to find help on RPi or Slack forums.
