Set a Bolt output low from a Slack request
Give a specific shutdown request a straightforward device action, with the instruction kept alongside the team's discussion.
Trigger
Channel Message Received
Triggered when a message is posted in a Slack channel (public, private, or multi-party IM). Does NOT match direct messages.
Action
Bolt IoT Digital Write
Tool to set a digital pin high or low on a specified bolt device. use when controlling actuators or leds via digital output.
Why this helps
A simple shutdown can be delayed when someone must manually translate a channel request into a device command.
- Translate a clear shutdown request into a low digital output.
- Keep a defined action close to the team conversation.
- Reduce manual copying from chat into a device interface.
Setup
Build it in a few focused steps.
- 1Connect Slack and Bolt IoT to Notis once in the portal.
- 2Create the automation in the portal or ask Notis conversationally.
- 3State the specific authorized shutdown request and device pin in one instruction.
- 4Choose Channel Message Received and a channel for run reports.
- 5Test with a safe indicator or test output using a real channel message.
Questions about this workflow
Can the output be set low?
Yes. Bolt IoT Digital Write can set a digital pin low.
Should every use of the word shutdown run it?

New Channel Created Trigger
Triggered when a new channel is created in Slack.
Check Bolt device online status
Tool to check whether a specified bolt device is online. use when you need to verify device connectivity before sending commands (e.g., control signals). example: 'check if device bolt1234567 is online.'
Channel Message Received
Triggered when a message is posted in a Slack channel (public, private, or multi-party IM). Does NOT match direct messages.
Bolt IoT Digital Write
Tool to set a digital pin high or low on a specified bolt device. use when controlling actuators or leds via digital output.
Direct Message Received
Triggered when a new direct message (DM) is sent to a user in Slack. Catches all DMs across all DM channels.
Bolt IoT Serial Read
Tool to read incoming serial data from a bolt device. use when you've initialized uart with serialbegin and need to retrieve serial data.

Triggered when a reaction is added to a message in Slack. Supports optional filtering by channel and emoji name.
Bolt IoT Serial Write
Tool to send serial data to a bolt device. use when you need to transmit ascii data over uart after initializing uart with serialbegin.
Message Reaction Removed
Triggered when a reaction is removed from a message in Slack. Supports optional filtering by channel and emoji name.
Bolt IoT Serial Write & Read
Tool to send serial data and read the response on a bolt device. use when you need to transmit ascii data over uart and capture its reply immediately.
Reaction Added Trigger
DEPRECATED: use `SLACK_MESSAGE_REACTION_ADDED` instead. Triggered when a reaction is added to a message in Slack.
