The Zembro Beacon uses Bluetooth 5.0 technology and advertises standard iBeacon, Eddystone (UID, URL, TLM), and sensor data simultaneously. The rotatable mechanical design makes the coin battery easily replaceable (battery should be replaced annually) The Zembro Beacon can be attached to objects by double-sided adhesive for indoor location monitoring. It is recommended that they be placed in the centre of each of the most utilised rooms in the house. Each beacon must be registered with the user account prior to use, which can be done during initial setup or by contacting customer services. Where specific location or room names are assigned to a device, that information will be provided on the guardian alert. √ Internal button: internal power ON/OFF push button to avoid accidental switching and neater product appearance. √ Easy to activate: open the rotatable housing, long-press “push button” for 3 seconds. √IP67 Waterproof: can be placed in areas where moisture is likely (e.g. kitchen and bathroom) although full submission is not recommended
