Nest Protect - 'Support'?


Since my Popp Z-Wave smoke detectors don’t work, I’ve replaced them with 9 Next ones, and installed the Nest App

I added my Nest Protect Smoke and CO Alarm device, but Homey doesn’t see to be able to do anything with it. e.g. when I test the Nest Protect Smoke and CO Alarm, Homey reports nothing.

It shows simple shows a CO and Smoke icon with NO written under each. What ‘support’ is the app supposed to give exactly?

That can you read on the app pages wich you mention yourself

Are you a troll Roy? Why do you think I posted here if what is written on the app page is sufficient?

Your asking only what the app support exactly. And what it should support stands exactly op that pages.

So not more than a correct answer to your question

You can use this app to:

  • Control and read the target temperature
  • Read the measured temperature
  • Get emergency notifications for smoke, carbonoxide and battery level
  • Use the Nest Away state in your Flows
  • Use HVAC (Heating, Ventilating, and Air Conditioning) in your Flows:
    • HVAC state (actively heating, actively cooling or not active) trigger and condition;
    • HVAC mode (heating mode, cooling mode, heating and cooling mode, eco mode or system is off) trigger, condition and action.
  • If set in a thermostat’s device settings: Homey can override that thermostat’s eco HVAC mode to regain control of the target temperature.

Apparently it can only display temperature and only emergency notifications for CO, smoke and battery. I figure testing is not the same as an actual alarm.

But if you want to be sure, ask the developer of the app, he must know.

Thanks for your constructive reply Peter. I left a message on GitHub and didn’t get a reply which is why I posted here.

I would expect that it should acknowledge a test otherwise how would you be confident it would send a signal in an emergency?

I guess the only way to find out is light a fire under it.

There is smoke detector test spray.

The test button does not send a smoke alarm to homey.
But I successfully tested the smoke alarm with the nest protect in the kitchen without a test spray and Homey said that nest protect reported smoke alarm.

Please keep in mind that Google is dropping support for nest.

You can find much about the Nest protect by searching to forum (including the many restrictions NEST have over API access to the protect) :
