I was looking for Active RFID Reader/Tags to use them as a Home Arrival sensors.
Because I am to...o lazy to pull something out frome my pocket, to push buttons, etc.
Finally I found what I was looking for. This is actually a door opening kit for dogs:
But in fact this is nothing more than Active RFID Reader/Tags.
Price from Autoslide is $315 but I found a brand new unopened kit just for $160
on eBay. This is not too bad for the Tag Reader and 2 Active Tags. Kit arrived today
and I aready tested it. It needs 12V DC power supply and the output is dry contact
relay. What could be better? It will be wired to the Zigbee Door Sensor and resulting
device will be Hubitat ready "Zigbee Active RFID Home Arrival Sensor".
Tested range is about 4ft as advertised. This is OK for my intended use case which
is "Atomatic Door Unlocking and Opening ". And it will be replacement for the currently
used BLE Beacons. Beacons are working perfectly fine but they are unsecured.
These RFIDs are secure.
