This article summarizes how the No Presence notification work, and how to activate it.
Somnofy and Guardian H10 uses radar signals to measure movements during the night. In health.somnofy.com, you define the distance from the sensor to the edge of the bed during installation.
When the patient/resident leaves the bed, the radar no longer receives any signals, and then the sensor interprets it as if the person is no longer present.
The No presence notification is especially useful for monitoring residents who may be at risk of falling when going to the bathroom at night. You will receive a notification if the person has not returned to bed within a certain number of minutes.
How to set it up
Under Notification rules and logs, select Add notification rule.
- Minimum time present (in the measurement area): 10 minutes
- Time not present (in the measurement range): 5 minutes
It is also possible to choose whether an OK should be sent notification if the user returns.
In addition, you can adjust the Active time so that the notifications are only sent at night, for example.
The device sends signals up to the cloud every 30 seconds and each epoch that is measured lasts 30 seconds. This means that it can take over a minute before you will receive a notification that a person has left their bed in some cases. We do not recommend setting the "time not present" to less than 5 minutes.
