Send a Bolt serial command from sent email

Turn a sent command request into a serial write, with the device and command stated in your email.

Trigger

Email Sent

Triggers when a Gmail message is sent by the authenticated user. It polls the 'SENT' label and emits metadata including sender, recipients, subject, timestamp, and thread ID.

Action

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.

Why this helps

Commands written down in email can be forgotten before they reach the device.

  • Trigger a serial write from a message you send.
  • Transmit the specified ASCII data over UART.
  • Get a report that records the automation run.

Setup

Build it in a few focused steps.

  • 1Connect Gmail and Bolt IoT once in the Notis portal.
  • 2Create an automation in Automations, New Automation, and name it.
  • 3Tell Notis to send the specified ASCII data from your sent email to the named device over initialized UART.
  • 4Pick Email Sent as the trigger and choose where run reports go.
  • 5Test by sending one real command for a device with UART initialized.

Questions about this workflow

Which emails trigger the workflow?

Messages sent by the authenticated Gmail user trigger the automation.

What must be ready on the device?

UART must already be initialized, and the email should identify the device and ASCII data to send.
