Read Bolt serial data when filtered sheet values change
Let a change in a filtered set of spreadsheet values prompt a serial read, so device output is easier to review alongside the trigger.
Trigger
Filtered Range Values Changed
Polling trigger that monitors Google Sheets filtered ranges for value changes. Uses snapshot-based diffing to detect when values matching a data filter change. Emits the matched values when changes are detected.
Action
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.
Why this helps
Serial data can be useful during an operations change, but remembering to fetch it at the right moment adds another follow-up task.
- Prompt a serial read when matching sheet values change.
- Bring device output into the run report for review.
- Reduce the chance of forgetting a manual data check.
Setup
Build it in a few focused steps.
- 1Connect Google Sheets and Bolt IoT once in the Notis portal.
- 2Create a new automation in Automations and give it a clear name.
- 3Tell Notis: when values matching the monitored filter change, read incoming serial data from the specified Bolt device and report the result.
- 4Pick Filtered Range Values Changed as the trigger and choose where run reports should go.
- 5Test with one real matching value change and review the output.
Questions about this workflow
Does this initialize UART?
No. The listed serial read action is for retrieving data after UART has been initialized with serialbegin.
What does the trigger provide?
It detects snapshot changes in values matching a Google Sheets data filter and emits matched values when changes are detected.

Supported Triggers and Actions
Notis builds workflows that link Google Sheets to Bolt iot. A trigger fires from one place; an action lands in another.
Google Sheets 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.
Aggregate Metric Changed
Triggers when an aggregate metric (SUM/COUNT/AVG/MIN/MAX) changes in a Google Sheets spreadsheet. This trigger monitors an aggregate calculation on a target column (optionally filtered by a search column/value) and fires when the calculated result changes.
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.'
Cell Range Values Changed
Triggers when values in a specified A1 range change in Google Sheets. This trigger monitors a specific cell or range of cells and fires when any values change.
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.
Conditional Format Rule Changed
Triggers when conditional formatting rules change in a Google Spreadsheet. Detects when rules are added, updated, or removed. Uses snapshot-based diffing to detect changes between polls.
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.
Data Validation Rule Changed
Triggers when data validation rules change (added/updated/removed) in a Google Spreadsheet. Uses snapshot-based diffing to detect changes between polls.
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.
Developer Metadata Changed
Triggers when developer metadata entries change (new/updated/removed) in a Google Spreadsheet. Uses snapshot-based diffing to detect changes between polls.
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.
Filtered Range Values Changed
Polling trigger that monitors Google Sheets filtered ranges for value changes. Uses snapshot-based diffing to detect when values matching a data filter change. Emits the matched values when changes are detected.
