Sonos One emits RF even in wired mode

Hi there,
I'm trying to disable all the wireless of the Sonos One SL speaker. I've connected it via Ethernet and enabled Wired mode. However, it still emits R.F., approximately 20 mW/m2. I suppose it's a Bluetooth module. When it's in Wi-Fi mode, it emits approx. 800-1000 mW/m2, which is enormous, especially when placing this speaker in the bedroom.
My suggestion for the product team is completely disabling Wi-Fi and Bluetooth modules when the device enters Wired mode.

P.S. I can upload a video with my measurement using a Cornet RF meter.

Have you disabled Wi-Fi under the One SL’s settings in the Sonos app?

At what distance are you measuring flux density?

Just a few centimetres above the speaker.

"A few centimetres" is vague. Are you familiar with the inverse square law?

You are right, and I understand this. The question is why the speaker emits any RF while it's plugged in ethernet and with wireless disabled?

It should work like an airplane mode.

However, even within a meter my device detects RF from the speaker as well, not so much, but it is.

It’s Bluetooth Low Energy, primarily used for setup purposes. Quite why it remains active is not clear but the emissions are tiny. The clue is in the name.

Why are you bothered anyway? I assume you must go outside occasionally, maybe even take the odd flight. Unless of course you spend your life in a Faraday cage?

I'm not wearing a foil hat, as you may imagine :)

I love tech devices, but I think we should reduce RF exposure when possible. For example, in a single room, there a lot of wireless devices: laptops, tablets, phones, smartwatches, headphones, IoT sockets, lamps, sensors, printers, speakers, air purifiers. So you could be surrounded by dozens of RF emitting devices. I'm trying to reduce these when possible by disabling wireless…
Do you think this exposure is natural and good for a human? There are some studies proving the harmful effects of constant RF exposure.
