    They say that the Sleep sends out short Wi-Fi signals while a person is sleeping but nothing about the signal strength. Good question to bring up to their Support team. (https://support.withings.com/hc/en-us/articles/360000220748

    Thanks, that article helps, although i would have preferred only Bluetooth emittance at night. Spurts of wifi worry me, so I limit using it to once a week or so. The thought of competing nightly against a sleep score is enough to keep me awake anyways! Nice product though, and it gives me the baseline that I need, but as an engineer, I certainly would be concerned about Wifi radio signals, even in spurts, close to my chest on a nightly basis.

    Also, given WiFi, you have be comfortable that it's sending your raw sleep data to Withings as you sleep (versus Bluetooth where data is sent to your phone and would more likely not be relayed to outside servers)!

    The key phrase from their article is: "The Sleep does not maintain a continuous Wi-Fi connection with your router."  Whereas, bazillions of products in your bedroom and house do stay constantly connected, which is (only in theory at that) more hazardous to your health.  For example, if you have a smartphone next to your bed that stays on, it's far more (only theoretically) unhealthy than something buried underneath a mattress, maybe even farther away, that only connects occasionally for quick bursts.

    They also said: " The Sleep doesn't emit Wi-Fi signals while you sleep". It means that the Sleep try syncronization when you are out of the bed in the morning. And "Your sleep data will still sync to the app even after disabling your Wi-Fi router at night and re-enabling it later in the morning. The Sleep attempts to upload data within 2 hours of you waking up. If the Wi-Fi router or internet connection is not active during this time, the Sleep will not attempt to send sleep data until the following morning when you jump out of bed." It means (theoretically) that the syncronization is at the morning when you jump out of the bed. But it will be more secure if the software switch off the wi-fi during the night. I'm not sure about that.
