Google Home Web Automation and Nest Protect Smoke Detectors not Triggering

BostonChas — Tue, 05 May 2026 21:21:04 GMT

Following the Google "Flash lights when smoke alarm is active" example at

Flash lights when smoke alarm is active example , I created a web based automation to signal to my Home Automation Hub that a 2nd Gen Nest Protect is alarming smoke or CO.

I had an unscheduled test of the automation and the actions never ran. The actions run fine if I manually run the automation from the top level automations screen. See next post for details.

Was being blocked from posting execution logs. Taking a screen shot seemed to work. There is nothing in the logs for a day or two prior to the smoke detector going off.
