- Keep local attendance state current
- Reduce manual tallying
- Capture device-side responses
Setup
Build it in a few focused steps.
- 1Connect Zoom and Bolt IoT in Notis once.
- 2Create an automation in Automations.
- 3Tell Notis to read the Bolt serial channel whenever a new Zoom participant is reported and summarize the returned data.
- 4Choose New Meeting Participant as the trigger.
- 5Choose a report channel and test with one participant record.
Questions about this workflow
