Turning off WiFi while I'm sleeping

[Kyle1980]

Is there a way to automatically shut this down while I'm sleeping. Don't want any transmission going on.

Wi-Fi should not be an issue as those trackers that use it only use it to download playlists and apps from the Fitbit App Gallery, and for faster firmware updates.

Bluetooth is another matter. All fitbit models use bluetooth to sync and provide notifications but there is no option to turn it off.

[Kyle1980]

Right, I didn't see one. That might be an important thing to add since
we're getting zapped by bluetooth 24/7. I'll have to stop wearing mine to
bed.
Thanks!

@Kyle1980  Not sure about the saving.

If you are using a phone with strong 3G, 4G, or 5G, and Wifi & weak Bluetooth signals and a watch with only intermittent weak Bluetooth signals all day, how does it help not wearing the watch at night? Other devices in the house or outside are most likely creating stronger signals.

The point of smart devices is to measure your health and tell you the time, if you don't wear it it can't do that.

For best results don't wear it in the day either and more importantly turn off your mobile phone if you are worried about being zapped.

Generally the further the distance a signal travels the stronger it is.

As Bluetooth probably covers the shortest distance, and is not continuous from the watch, it is probably the least "zapping" of the 3 types.

See article which covers some aspects, namely "power reception order - WiFi >4g >3g>Bluetooth". 5G is another issue.

My watch actually transmits to the other side of the shop, about 100'. So
six hours without being blasted while I'm sleeping would definitely be
better since sometimes my hands would be near my head.

There seems to be a confusion.

Bluetooth won't go 100' - it's maximum is about 30'.

You are probably talking of Wifi which can perhaps do 160'.

But as @SteveH mentioned your watch does not use Wifi most of the time, except when its on the charger, never normally on the wrist.

[Kyle1980]

Sounds like I need to ditch the Fitbit and get a IWatch. My wife can shut
down that stuff. That's why they make airplane mode.

Not sure that the Apple watch can turn off Bluetooth, it can turn off Wifi. But as Wifi is already OFF with the Fitbit its not relevant.

The Fitbit only uses Bluetooth to communicate with the phone in the same way the Apple watch does..

[Kyle1980]

I disagree. If I'm out on the shop floor and if my phone is receiving a
call. The send a signal, about 100' to my Fitbit so I have a choice to
answer it or not. That tells me it's always on. Maybe it's only receiving
until it needs to send a signal to the phone. That's unknown to me.

Thats not how it works.

The signal to the watch comes from the phone over Bluetooth [max 30'], not across the floor.

It is highly likely that the weak Bluetooth signal is quiescent when not in use [so virtually nil].

[Kyle1980]

I disagree. This signal is going through a wall and to a panel saw that I'm
running about 70-100' away.

[Guy_ · Accepted solution]

You are talking of a mobile [coming from miles away] or wifi [from a nearby router] transmission to your phone.

Neither has anything to do with whether to wear your watch, as neither of those two signals arrive at your watch.

The only communication your watch is normally able to do is the Bluetooth one with your phone.

Probably best to contact Fitbit Support directly. They may be able to help you further.

When my cellphone, Moto Z2, receives a call. My phone sends a signal to my
phone and I receive a message on my watch that a phone call is present and
gives me a option to receive it or hang up. Once again my phone is behind a
wall and transmits that 70-100' to where I'm at to my Fitbit.
