Recheck a Bolt device after a Slack flag changes
Give a changed status marker a quick follow-up so the team can coordinate around current device availability.
Trigger
Message Reaction Removed
Triggered when a reaction is removed from a message in Slack. Supports optional filtering by channel and emoji name.
Action
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.'
Why this helps
A changed signal in chat can leave people unsure whether the underlying device has recovered.
- Start a fresh online check after a designated marker is removed.
- Make device recovery easier to follow up on.
- Reduce the need to remember a separate status lookup.
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 for it conversationally.
- 3Describe the removed reaction that should prompt an online check for the relevant device.
- 4Choose Message Reaction Removed and select a channel for run reports.
- 5Test by removing the agreed reaction from a real test message.
Questions about this workflow
Does removing the marker guarantee the device is online?
No. The action checks current online status and reports what it finds.
Can it run when unrelated reactions are removed?
Use the trigger's available reaction and channel filters, and make the instruction specific.
