Silent until it matters
The tag sleeps in deep-standby, drawing only tens of microamps. A motion or tamper event wakes it; it sends a signed event to the cloud; it goes back to sleep. You get years of battery from a single coin cell.
IoT · Tamper detection · Multi-channel alerting
Magpie is an ultra-low-power tag you fit to a door, gate or other small opening. The instant it senses unauthorised movement or tampering, it wakes up, phones home over cellular, and alerts you — by SMS, email, or voice call.
The tag sleeps in deep-standby, drawing only tens of microamps. A motion or tamper event wakes it; it sends a signed event to the cloud; it goes back to sleep. You get years of battery from a single coin cell.
Even where cellular coverage is marginal, Magpie uses non-terrestrial-network fallback — so remote sheds, rural gates and boundary doors stay connected.
SMS, email, voice call — set per tag, per contact, per time of day. Arming schedules keep it quiet when you're home and noisy when you're not.
Each tag presents a unique mutual-TLS certificate signed by our CA. Devices can only talk to their own topic. Event payloads never contain PII; owner identity is resolved server-side.
