hello Automaters. thanks for tuning in again the Nest Protect without Wi-Fi
what does that situation look like and is there anything on the Nest Protect
that allows it to operate without Wi-Fi let's get going first off we're going to
discuss what the detector or what the Nest Protect devices need in order to
operate as basic smoke and CO detectors they do not need Wi-Fi they literally
need to be powered and they will be capable of detecting smoke fire co in
your home and they also have the occupancy sensor onboard now this goes
for the wired or the battery models essentially all you need for them to
perform the very basic function of protecting your home in terms of an
audible you know notification that is possible
without Wi-Fi what is also possible without Wi-Fi is the ability for the
devices to talk to each other and you might think that well that's not
possible it doesn't have the interconnect cable capability or
termination capability so there's an interconnect cable in most newer homes
and and this is based on fire codes and fire standards in a lot of nations
around the world but you know here in Canada
I have a third cable so I don't just have the white and the black that powers
my device I also have a third cable called the interconnect cable in my
ceiling and that cable allows all of my different detectors in my home to
receive an alarm when one of them receives an alarm and it ensures that
there's noise throughout my home entirely so that interconnect cable that
isn't on the Nest protector you can't terminate that cable on the Nest Protect
so what are they doing how can they not need Wi-Fi and also not use that
interconnect cable and still be allowed in countries like ours that have this
standard that requires interconnection the answer for that
calls comes from something called thread and thread is essentially a protocol or
a standard that is being used and being spearheaded by Google and or Nest and
now there's a lot of other makers and we'll talk about that in separate videos
but as as these companies develop the thread protocol what they've done with
the Nest Protect device is actually implanted thread on here and thread is
capable of communication very very similar to ZigBee and other mesh
networks but the difference is it's IP based as well so the device still has an
IP address and IP version 6 address and it's able to communicate in a mesh
format to other devices with the thread capability on board so what does this
mean for you when there's no Wi-Fi in your home what does the Nest Protect do
and how do those devices communicate they're communicating through this
thread capability and therefore your interconnection remains all the time so
what has to happen is your Nest Protect devices have to be close enough for that
and what I'll tell you is because it's a 2.4 gigahertz the same frequency as most
what Wi-Fi is in your home and end the ZigBee protocol actually it will have
relatively that same distance of anywhere from 10 to 40 meters and you
know bigger walls and things like that thicker walls metal doors that will
interrupt that thread communication just the same as Wi-Fi so what does this all
mean what do you lose when Wi-Fi goes out in your home what the Nest Protect
devices all you lose is the notifications to your phone essentially
and notifications to other services like if this than that or Amazon or or Google
Assistant any of those integrations that you've created between your Nest Protect
and other smart home devices those will go away but your main capability of
having an esper hacked protect your home in terms of
smoke and CO and fire that will still be there your ability to have
interconnection between those devices that will still be there so there you go
guys I hope this was a good piece of information for those of you looking to
go purchase Nest Protect devices this is really I think important stuff for you
you will always be protected even if your Wi-Fi goes down and I think that's
the most important thing today so thanks for watching everyone
