Switch off WiFi and Bluetooth PERMANENTLY from Sonos One

Technology always adapts to changes with some delay. Antivirus programs appeared some time after viruses appeared. Similarly, WiFi high encryption and the ability to disable the publication of your network WiFi name. I don't rule out that it was postulated on the forums ;-)
What will come after BLE? I can imagine - this is an extreme case - potential thieves walking down the street, scanning for BLE signals, publishing how expensive equipment is in which house :-( The ability to choose - whether I turn BLE on or off makes sense :-)

I understand your concern with respect to potential biological consequences of emissions. There are considerations for manufactures and consumers.

On the manufacturing side it is much more expensive to add a mechanical switch than to provide another option on a menu. Also, over the long term, the mechanical switch is a failure point. Yes, there are very reliable switches -- at a higher cost. A network jack (and the cable) are also costs and small reliability risks.

On the consumer side “everything is wireless now, right?”. There would be backlash if a wired connection was required in order to re-enable the radio. Less and less consumers are aware that their Gateway has network jacks because the ISP’s installer simply makes sure that the user’s phone can access the service, then leaves the premises. This confusion would result in more support calls -- increasing costs for manufacturers. There will also be rants in communities, such as this, complaining that their BT has now stopped working. suggesting that a class action lawsuit is needed.

I would welcome a switch. My personal experience with BT has not been great and I don’t have much use for it, but I do have a noise cancelling headset that I’ll occasionally use to protect my hearing from excessive noise in my environment. Of course this places the BT radio very near my brain. I must choose between potential brain damage and well documented hearing damage. I’m constantly struggling with BT connectivity issues of my various devices. Maybe there is a wired noise cancelling headset somewhere.

The latest SONOS models do include a mechanical switch associated with BT. I don’t know if this completely removes power from the BT radio or simply disables it’s function. The switch is a simple pushbutton and I suspect that a reboot or Factory Reset will enable BT again. I haven’t bothered to test this.

I don’t think that we have a complete understanding of potential long term outcomes on evolution caused by radio emissions or if the public will care. There is a large amount of data documenting bad outcomes for consuming certain foods, yet production continues and the public continues to gobble them.

I was too late to get One gen 1. I’m either stuck with gen 2, or need to go back to the drawing board. Does anyone know if Ray is the same as One? Or can BT be turned off?

BTW, I’m going to replace the battery in my old Bose buds to avoid BT headsets. It’s not user replaceable, but still possible to do.

Consider the used market, sadly it is far smaller than expected given the number of folks that have posted that they are selling all their Sonos.

I’m a big fan of having options, sadly it seems the ones I want aren’t popular enough to see Sonos implementing them.

From an RF exposure standpoint turning off the WiFi and Bluetooth on an active cell phone is going after the lesser of three evils.

Turning off WiFi to a non-Ethernet connected Sonos would remove the ability to control it.

Several good points for other reasons to turn off Bluetooth.

Just have found another interesting piece for this thread. Reading next devices manuals, looking for one with BT off switching, there is a sentence: 

“About Bluetooth communications
Radio waves broadcast from this unit may interfere with the operation of medical devices. Make sure you turn off the power of this unit and Bluetooth device in the following locations as radio wave interference may cause malfunctions.
- Hospitals, trains, aircraft, petrol kiosks, and places where flammable gases are generated
- Near automatic doors and fire alarm”

So many potential clients are excluded this way. The possibility of switching off BT would stop their protests with banners “Network speakers for everyone!”, “Ethernet rulez!”  ;-)

Did that device use Bluetooth or Bluetooth Low Energy?

I have several Bluetooth LE devices that do not have that warning.

Who knows :-) 

I've noticed that manufacturers don't like to brag about the transmitters they put in their devices. Here is the source of the instructions for the equipment I wrote about (not cheap one):

Interestingly, the fine print in this manual states that you must turn on Bluetooth on your phone if you use the phone app to control the device (HEOS app). It's unclear whether it's only during installation or all the time, but from the description it looks like it's all the time...
There are probably some meters to measure whether the device is transmitting something and I would gladly buy it, but they are probably expensive toys.

That doesn’t sound like they’re using Bluetooth Low Energy: “you must turn on Bluetooth”. If so, comparing energy emissions like this and Sonos BLE is rather like comparing apples and oranges. And not knowing for sure makes it more like comparing apples with chalk. 

I did find this tool. I cannot vouch for its accuracy or effectiveness.
