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! Review: Recommended! - I used 3 of these to develop a system to track my cars in the garage. They worked extremely well. Documentation and the corresponding app were excellent. 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. - Button Trigger allows the beacon to be configured to broadcast only after a specific button click, or to broadcast a different UUID after a specific button click, or to broadcast one UUID at all times but to switch to a modified UUID for a limited period after a specific button click. The movement sensor feature has similiar configurability options. These unique powerful features open up a wide range of custom usage cases for this beacon. - Long Range Connectivity: Utilizes advanced BLE 5.0 Bluetooth technology for extended transmission range and improved signal stability - Multi-Purpose Tracking Device: Suitable for asset tracking, indoor navigation, proximity marketing, and attendance monitoring applications - Low Energy Consumption: Designed with Bluetooth Low Energy technology to maximize battery life and minimize power usage - Built-in Movement Sensor: Equipped with motion detection capabilities to track and monitor device movement and activity - (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.) ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08PCHJ1KS | | Antenna Location | Driveway, Garage, Garden, Lawn, Sidewalk, Terrace, Walkway | | Battery Average Life | 16 months | | Battery Life | 16 months | | Best Sellers Rank | #38,533 in Electronics ( See Top 100 in Electronics ) #179 in Motion Detectors (Electronics) | | Brand | Blue Charm Beacons | | Compatible Devices | All smartphones with bluetooth capability and also other BLE beacon scanner devices | | Connectivity Technology | Bluetooth BLE 5.0 | | Control Method | App | | Customer Reviews | 4.2 out of 5 stars 46 Reviews | | Enclosure Material | Acrylonitrile Butadiene Styrene (ABS) | | Item Type Name | iBeacon | | Item Weight | 0.01 kg | | Manufacturer | Blue Charm Beacons | | Material | Acrylonitrile Butadiene Styrene (ABS) | | Mfr Part Number | BC-021 | | Model Number | BC-021 | | Number of Batteries | 1 Lithium Metal batteries required.

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 ### ⭐⭐⭐⭐⭐ Robust and reliable ESP32 BLE iBeacon tracking in Home Assistant *by J***A on January 13, 2026* Absolutely love this little guy on my keyring.

Documentation and the corresponding app were excellent. Recommended ### ⭐⭐⭐⭐⭐ Works well, good defaults, robust firmware *by R***R on May 18, 2024* Works great out of the box. The KBeacon config utility has tons of great features including enabling TLV broadcasts for battery / uptime monitoring and forcing "always on" mode. Note that you can find the same item from Chinese sites at half the cost. I still prefer supporting the small company that sells on Amazon w/ quick delivery. ## Frequently Bought Together - Blue Charm Beacons - Bluetooth BLE iBeacon (BC021-MultiBeacon) with Movement Sensor - Long Range BLE 5.0 - Blue Charm Beacons - Long Range Phy (300m) Water-Resistant BLE iBeacon (BC04P-MultiBeacon) - w/Adjustable Movement Sensor - Blue Charm Beacons - Bluetooth BLE iBeacon (BC-U1-USB MultiBeacon) - USB Powered - Long Range BLE 5.0 --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://botswana.desertcart.com/products/379809289-blue-charm-bc021-multibeacon-bluetooth-ble-ibeacon-with-button-trigger](https://botswana.desertcart.com/products/379809289-blue-charm-bc021-multibeacon-bluetooth-ble-ibeacon-with-button-trigger) --- *Product available on Desertcart Botswana* *Store origin: BW* *Last updated: 2026-08-18*
