I know that a lot of fitbit type devices already are capable of SpO2 tracking and it's very useful in monitoring sleep
I am thinking of looking to upgrade the measurement device and obviously the more reliable measurements the better.
I do, however, think that an annual charge of £80 is a bit of a try on and that will motivate me to look for alternatives (particularly as fitbit is not that reliable for sleep analysis anyway).
Withings, however, is as far as I can tell useless. They provide an under the mattress sensor which I have found to be approximately zero utility.
Yeah a lot of the sensors try to use motion as a proxy for sleep cycles; which will correlate for a lot of people, but it's still a proxy for
There's no reason a tympanic sensor couldn't pick up heart rate through a mattress, but it's going to need good running calibration to cope with rolling and movement (despite that some folk really like the withings system)
Heart rate and SpO2 I do see as being the most useful measurements with current generation home technologies.
Not that they help you get to sleep; but they can give you an indication of why you might be waking, or more usefully if you're not, but are suffering otherwise.
