Trigger button to run a script in Home Assistant

I configured a button (Runlesswire Click) to log diaper changes for my new baby. The diaper changes are logged in a Google Docs spreadsheet. I set up a simple public facing Google Form that I could run unauthenticated curl requests against. I then configured Home Assistant to run that curl command when the button is pressed. Instant diaper logging by the press of a button.

Lessons learned:

  • Zigbee Home Assistant (ZHA) does not yet support the Zigbee Green protocol, which the RunlessWire Click uses. I had to pair the switches to my Hue hub instead.
    * It looks like they’re getting close to supporting it, though: https://github.com/zigpy/zigpy/pull/1282

Here was my process:

  • Create Google Form
  • Obtain form ID from URL bar
  • Get pre-filled link to get names of fields by clicking the three dots on top right and clicking “Get pre-filled link”. Make note of the names for each entry e.g. entry.1363419348

  • Curl command is:
    curl https://docs.google.com/forms/<FORM_URL>/formResponse -d ifq -d <ENTRY_NAME>=<ENTITY_VALUE> -d <ADDITIONAL_ENTRY_NAME>=<ADDITIONAL_ENTRY_VALUE> -d submit=Submit
