It offers a long transmission range up to 90 meters, customizable broadcast formats (iBeacon, Eddystone TLM/UID), and real-time battery level monitoring. Compatible with all Bluetooth smartphones and popular home automation platforms like Home Assistant, it delivers reliable, low-latency presence detection and automation triggers with a 16-month battery life on a replaceable CR2032 cell. ## Description Model Number: BC021A unique beacon that includes a button trigger AND movement sensorThe button and/or movement sensor can optionally be configured so that beacon only broadcasts for X seconds after button is pressed or beacon is moved (for an alarm or alert-type function). Alternatively, it can broadcast a different UUID after button is pressed or beacon is moved. This feature adds a powerful level of active (button press) or passive (adjustable movement sensing) interaction to the beacon. Transmit distance: 0.2-90 meters Wide Range of TX settings. Long Range BLE 5.0 Shows battery level in broadcast.This unique Multi-Beacon broadcasts your choice of iBeacon, Eddystone TLM, Eddystone URL, and/or Eddystone UID format. Monitor battery level via app.Beacon name, UUID, TX broadcast strength, broadcast interval, major/minor, etc. are customizable via our free apps.Our website has very detailed step by step instructions and screenshots under the Quick Start Guide menu.Specifications: Transmission: iBeacon, Eddystone URL, and/or Eddystone UID format.

Works great with Home Assistant too. See our website for some sample projects using beacons with HA. (Under the "Usage Examples" menu at the top) Review: Home automation must have.. - Been using this for a few weeks now. Connected it with Home Assistant and ESPresense. Now I can run automations on arrival/departure etc. Easy setup, 100% reliable. I am sure there are other ways to add further functionality but aces what I need now. Review: Robust and reliable ESP32 BLE iBeacon tracking in Home Assistant - Absolutely love this little guy on my keyring. Works as a super reliable and almost zero latency presence detector for Home Assistant automations when I arrive and leave home. I configured my ESP32 AIR-1 and MSR-1 air quality sensor and mm wave radar devices as BLE proxies and they do a great job of picking up the advertisements. Absolutely wonderful to finally have something so reliable and instant to trigger automations when I leave and arrive my NYC apartment. Absolutely zero false triggers/flapping in my year of using it. It's super configurable with the phone app (you can pair right after you turn on the device to set up). It's definitely worth it to take the time to read the documentation--there is even a button functionality you can configure for an additional remote trigger after you arrive home. Highly recommended! ## Features - Our new generation compact beacon with a unique button trigger option AND movement sensor. Long Range BLE 5.0 but also compatible with BLE 4.0. Shows battery level in broadcast. Button and/or movement sensor can be configured to trigger different broadcasts. - Broadcasts your choice of iBeacon, Eddystone TLM, Eddystone URL, and/or Eddystone UID format. Eddystone TLM broadcasts battery strength, temperature, and broadcast count data every tenth broadcast. (This is NOT an Eddystone URL beacon for broadcasting your website or ad message to nearby phones. That service has been SHUTDOWN WORLDWIDE by Google as of Dec 6, 2018.) - Free configuration apps for iPhone & Android allow you to adjust settings according to your needs. - Transmit distance: 0.2-90 meters.

Anything like our standard iBeacon protocol beacon or any other iBeacon here on Amazon will NOT work because we are all broadcasting the "Apple" manufacturer ID code at the beginning of our beacon broadcasts; also our broadcast format is standard iBeacon, not what you need. You need something that broadcasts a custom set of IDs; that can't be done with regular iBeacons. If you are a bit techy, you could use an ESP32 to accomplish this goal; you can order them here on Amazon for cheap. You would need to download a beacon sketch for it, and then customize the sketch to broadcast the custom IDs that the droids recognize. No guarantees, but I found some random person on the internet that said the following: "You can try Manufacturer Id <0x0183>, with Manufacturer Data 0x-03-04-44-81-82-01 for an R-series, or 0x-03-04-44-81-82-02 for a BB-series. Note that they're not actually beacons - they're advertised as a non-connectable BLE peripheral with no GATT services. Also, the Droids have a timer in them to only react every few minutes, to stop them becoming to chatty as they walk around Batuu." **Q: I'm looking for a device to use for presence detection in home assistant or hubitat. i saw someone did this. can post a link to your solution?** A: Using these in conjunction with ESPRESENCE and Home assistant for precise room tracking of my devices. So far it's good (takes a few seconds to update usually). ## Customer Reviews ### ⭐⭐⭐⭐⭐ Home automation must have.. *by C***R on 23 July 2026* Been using this for a few weeks now.
