Hello! It only took two years but we have developed a Zigbee-based sensor that when affixed to a bed, registers 97% accuracy when compared to electrocardiogram (ECG).
We leverage the sensors for monitoring the wellness and safety of elderly individuals in senior living environments, but there are applicaitons in sleep analysis, recovery analysis, baby monitoring and much, much more.
The payload, reported every second, includes:
- heart rate
- respiratory rate
- status (bed empty, bed occupied, movement detected)
- relative stroke volume
- heart rate variability
- measured fft magnitude
- beat-to-beat
- beat-to-beat1
- beat-to-beat2
- timestamp
About the sensor:
- CC2562P-2 (eByte module)
- TI Z-STACK 3.0 firmware with OTA implemented
- Mains-powered Zigbee Router
- Works with ZHA and Z2M
We’ve had great success deploying 100’s of these sensors in our communities and we would like to extend the reach of our novel technology.
Any interest here from the awesome Home Assistant Community?
This is super interesting, and I can understand the price considering all features. But 200$ is way too much for in/out of bed automations I want to accomplish.
@dedline Depending on price and available analysing applications/tools I think that it could definitely be interesting to combine sleep analysis and bed occupancy, however for me personally it would have support two people in one double bed (e.g. queen size bed / kings size bed), even if two sensors are a requirement.
Suggest also looking at the competition for target audiences that are looking for easy-to-use and analyze , such as the Withings under-mattress sleep tracker (Sleep Analyzer) → Under-mattress sleep tracker - Sleep Analyzer | Withings
Thanks for commenting and contributing so much to open source Zigbee community. I’ve benefited a lot from your posts over the years.
We provide Sleep Analysis Library for our facility customers. I would need to stand-up an S3 bucket and leverage existing API Gateway + Fargate to provide responses via REST. Would also then need to build out flows for HA, AppDaemon, NodeRed, etc… for clients to call the service. We could do this.
I’ll test the two people in a single bed this week and post it.
Thanks for posting Withings! I’m also thinking about how our sensor competes with https://www.owletcare.com/.
That is a good business idea too! I would have personally bought something like that if it had existed when our boy was a baby as he had astma and it got really bad when he was sick, …but then it would have needed an simple app for dummies considerng we got even less sleep we got at that time
I tested the sensor with two people in the bed. When I leave the bed, the sensor picks up my wife, calibrates to her vibrations and renders an accurate reading on her after vitals after ~ two minutes.
Sent out a batch of orders this weekend. Following up via email!
