Measured using ISO/IEC 24734, excludes first set of test documents. To enable HP Roam, some devices may require firmware to be upgraded and an optional accessory to add Bluetooth® Low Energy (BLE) beaconing capabilities. Dependent upon country setup specifications. Wireless performance is dependent on physical environment and distance from access point and may be limited during active VPN connections. Use of the HP Trusted Platform Module may require a firmware upgrade. Certification applicable to HP Managed and Enterprise devices running HP FutureSmart Firmware version 4.5.1 and later. Third-party certification based on Common Criteria Information Technology Security Evaluation ISO/IEC 15408 Standard requirements as of May 2019. HP Web Jetadmin is free and available for download at. ![]() So I just set a rule to automatically close both doors if we are not home or at 10pm (if not home).Some features enabled by future HP FutureSmart firmware upgrades may not be available on older devices, if for example, physical product characteristics limit the functionality of the new feature. I guess I could put a delay on it, but I would NOT want the door to start closing when the car is still pulling out (or in). Must have thought the beacon left and started to close the door. I did try closing the door automatically when leaving, but that got scary when the I pulled out and then the door closed immediately. Tried with the other vehicle, worked exactly the same. As soon as I turned into the driveway and approached the door, the correct door opened. Pulled out and closed door manually, then drove down the block and came back. Started the car (in the garage) and door automatically opened within 5 seconds (good safety feature, normally I would open the door before starting the car, but just wanted to see what happened). Set Hubitat rule to open the correct garage door when the vehicle arrives (not using distance setting). Put a RadBeacon USB in one vehicle and a Blue Charms USB in the other. The good news is that my app easily detected the new beacon and allowed me to create a new device for it.ĭoes anyone know off-hand if sending beacon data to hubitat every second would put too much strain on the device? Right now I have the gateway set to report every 5 seconds, which is great for detecting presence, but not so great for calculating distance (need more data and faster to predict distance better). Will see how well it works with the rssi and distance calculations. I finally got my car back for service (which had my radbeacon in it), and I just got a blue charms beacon, so we’ll test both of those out with both cars soon and let you know the results. ![]() Then you could setup rules that are based not only on beacon presence, but also rssi and/or distance. I am thinking of still setting the rssi and estimated distance calculation on the device when the beacon is detected. I read one article that says you’d have to sample rssi and use that with measured power for a period of 20 seconds and average together (throwing out super high or super low values) to get a more accurate distance e prediction (and that’s with the beacon not moving). And the fact that the beacon may be moving doesn’t help. The further away the beacon is, the less reliable the distance calculation. Determining the presence of a beacon is easy, and getting the rssi is easy, but calculating distance is much harder. The problem is that the distance calculation fluctuates because it’s measuring a radio signal strength. So with the April Brother BLE gateway, I can easily obtain rssi and calculate distance to the beacon. ![]() I haven't written a driver before but I wouldn't imagine a driver to report RSSI to hubitat would be that hard, its surprising how nobody has written one, is it because it's hard or nobody cares about BLE? ![]()
