Send a Bolt command and read its reply from Slack
Pair a clear device request with its immediate serial response so the next step is easier to decide.
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 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.
Why this helps
When sending a device instruction and checking the reply are separate tasks, the result can be missed or delayed.
- Pair an approved ASCII send with an immediate response capture.
- Reduce manual coordination between command and result.
- Keep the exchange attached to the channel request.
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.
- 3Write one instruction specifying the approved serial exchange and the channel request that should start it.
- 4Choose Channel Message Received and select a channel for run reports.
- 5Test a safe exchange on a device with UART initialized.
Questions about this workflow
What does the action do?

Supported Triggers and Actions
Notis builds workflows that link Slack to Bolt iot. A trigger fires from one place; an action lands in another.
Slack triggers
Bolt iot actions
Recurring trigger
Notis starts this workflow on a schedule, such as daily, weekly, or during business hours.
Analog Read
Tool to read the analog value from a specified pin on a bolt device. use when you need sensor readings (0–1023) after confirming the device is online.
Webhook trigger
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
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.
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.
Message Reaction Added
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.
