Shelly BLU Motion
Short device name: SBMO-003Z
Functional description
The device can detect movement using Passive Infra Red technology. It transmits motion event on the first detected movement and starts a countdown counter loaded with the Motion Blind Time value. When the time expires, the device emits No Motion event. If a new motion is registered meanwhile, the timer is reloaded and restarted.
Device specific features
Beacon mode
If active, the device will send periodically single advertising packets with the last status. This can be used for example for illuminance reporting.

Motion test mode
Double press starts motion detection test mode for 1 minute. Motion event is transmitted on every motion detected regardless the blind time. Led flashes longer on each detected motion.
