This is a safety feature for a science lab,
I have a flow set up that monitors water flow from a tap (for water cooling chemistry experiments), it is read as a frequency. The whole purpose of it is if the water is accidentally turned off, or water is shut off to the building it then turns off the power to the heating mantles via a tp-link switch (using the Kasa node).
I have that part of the flow all working correctly and tidy. I would now like to send a message to a Slack channel to tell all users the water has been turned off. We use slack as our work messaging system, so this is very integrated into my workplace.
Could anyone explain how to get Node-RED using nodes to trigger a message in a specific Slack channel? The easiest method is best, I can use IFTTT or Slack API, just need some guidance.
I am not a coder or computer engineer, and I have been getting rather confused with all the new terminology I have come across, (Webhooks, OAuth Tokens, Slack API, Scopes etc)
Thanks in advance for any help or clarity on the issue
