I have 2 sleep analysers one for either side of my bed. I use it for sleep tracking but my main use is for home automation (using home assistant). This works fairly well but I have noticed a few false positives for "in bed". Sometimes there is nothing on the bed other than the mattress and I've noticed it detect sleep. I've tried recalibrating to ensure it got the correct pressure for the empty bed but it still thinks there is someone in the bed.
I wonder if there is a more intuative way of setting the "in bed" flag i.e. not just that there is pressure on the bed, but there is also a heartbeat detected?
Alternatively and this is probably more inline with the root cause of the issue, I think the calibration for someone not in the bed i.e. baseline pressure vs someone in the bed is not correct. It seems far too sensitive (even with senstivity set to low) from a "in bed" perspective, fine the sensitivity for detecting a heartbeat I appreciate needs to be far more sensitive, but surely the weight of someone getting in bed should be a significant change in pressure, from the bed being empty?
Maybe a general value of significance can be set for pressence detection? Or perhaps the calibration could include you doing a two step process, with the bed empty and the bed occupied? Or even a configurable "in bed" pressure/sensitivity range/threshold you can set in the app specifically for presence not heart rate/breathing?
I'd love to know Withing's view on this and if there is any testing I can help with on improving this features reliability I'd be happy to assist.
