Read a Bolt sensor value from a Slack DM
Get routine sensor data from the private conversation that needs the answer, with fewer manual handoffs.
Trigger
Direct Message Received
Triggered when a new direct message (DM) is sent to a user in Slack. Catches all DMs across all DM channels.
Action
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.
Why this helps
A small data request can consume time when it requires switching tools and relaying a result back.
- Start a sensor read from a DM asking for a value.
- Reduce manual relaying between chat and device tools.
- Keep routine information requests focused.
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 to set it up conversationally.
- 3Write one instruction for the sensor value request and the device pin Notis should read.
- 4Choose Direct Message Received as the trigger and select the run-report channel.
- 5Test with one real DM and a known online sensor pin.
Questions about this workflow
What values can the action read?
Analog Read returns a sensor value from 0 to 1023.
Does it initialize the sensor or UART?
This action reads an analog pin; UART initialization is not part of the described action.

Supported Triggers and Actions
Notis builds workflows that link Slack to Bolt iot. A trigger fires from one place; an action lands in another.

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.
