Nest protect - Sensors and binary sensors

Configuration
1

I setup a Nest Protect in HA.
There are A LOT of sensors and binary sensors for it.

Does anyone know what specifically each one is and what state option they have available? (mostly talking about the smoke and CO ones (1 sensor and 2 binary sensors for each)
Without knowing this, very hard to configure automation and notifications…

Or maybe suggestion on how to setup good notifications with automation using it…
Thanks in advance for any assistance or guidance…

on the basis that most of them are binary_sensors, you can check their class and what values they could be.
Here is a reference to various classes:


for the other non binary sensors, I guess you could set an automation on the value not being what you currently have, e.g. sensor.1er_etage_nest_protect_battery_health != "Ok"?

Thank you, that was helpful (the device classes for binary sensor)
Is it possible to use the “!=” in alerts? or it’s just in automations?

I don’t believe so, I think you’ll need to create a template_sensor and use this for your alert

ok, thanks.

Also, anyone knows what are the “severity” ones? Those aren’t mentioned in Nest-protect docs…
If I would have to guess, I would say it’s when the CO or smoke reach a higher level, it activates those binary sensors…

My guess is, that it is the one defining how it informs you of the severity of the situation. I don’t have one of these yet, by my understanding is, that it will inform you nice and easy, if the situation is not critical. E.g. the Co2 level is above the accepted, but not dangerous. If, however, the Co2 level is at a critical level, it will start a louder alarm.
Is that correct?

Yes, I think you’re right.
I guess the best way to figure all this out will be to really test each alarm and see how the sensors react…

light a camp fire underneath and see how it reacts :smiley:
