📡 Best Bluetooth Beacons (iBeacon & Eddystone)
10 BLE beacons for indoor positioning, proximity marketing, attendance, asset tracking and app development: Blue Charm, Feasycom, DX-Smart and DIY nRF52840 boards.
✅ 10 Beacons Reviewed
✅ iBeacon, Eddystone UID/URL/TLM
✅ Battery, USB & DIY
✅ Honest Pros & Cons
A Bluetooth beacon is a small BLE transmitter that repeatedly broadcasts an identifier. Phones, gateways and apps nearby read it and estimate distance from signal strength (RSSI). That simple idea powers indoor positioning, museum and retail proximity apps, employee attendance, room-level presence in Home Assistant, and asset tracking with BLE gateways. The two main formats are Apple’s iBeacon (UUID, major, minor) and Google’s open Eddystone (UID, URL and TLM telemetry frames).
This guide compares 10 beacons on Amazon, from configurable Blue Charm MultiBeacons with buttons and motion sensors to long-range IP67 Feasycom tags and nRF52840 boards for building your own. It’s part of our BLE devices series; for consumer item finders, see our Bluetooth trackers guide.
💡 Reality check before you buy: Beacons only broadcast; they don’t track themselves. You need an app, SDK, gateway or Home Assistant to listen and act. Distance estimates from RSSI are approximate (think “near, close, far”), and walls, bodies and metal reduce range. Advertised ranges like “400 m” are open-air figures at maximum transmit power, which also drains the battery fastest. Note that Google’s Physical Web notifications for Eddystone-URL were discontinued, so URL beacons now need your own app to be useful.

🔍 How to Choose a Bluetooth Beacon
🏷️
Protocol Support
Choose beacons that broadcast both iBeacon and Eddystone (“multi-beacon”), so you can switch formats or run them at the same time as your project evolves.
⚙️
Configurability
You’ll want to set UUID, major/minor, advertising interval and transmit power from a phone app. Check the vendor app quality and whether configuration can be password-locked.
🔋
Battery vs Range
Battery life claims assume default settings. Faster advertising and higher transmit power improve detection but shorten battery life. USB beacons avoid the trade-off for fixed spots.
🏃
Sensors and Triggers
Motion-triggered beacons sleep until moved, saving battery for asset tracking. Button beacons work as panic or call buttons that broadcast on press.
🌧️
Enclosure
IP67 beacons survive outdoors, in warehouses and on vehicles. Indoor beacons can be smaller and cheaper. Consider adhesive, screw or lanyard mounting.

❓ Frequently Asked Questions
What’s the difference between a beacon and a Bluetooth tracker?
Beacons broadcast an open, configurable ID for your own app or system to use. Consumer trackers like AirTag use encrypted, proprietary networks for finding lost items. See our Bluetooth trackers guide for item finders.
How accurate is beacon indoor positioning?
RSSI-based positioning is typically room-level or a few meters at best, depending on beacon density and calibration. For sub-meter accuracy, look at Bluetooth direction finding (AoA/AoD) or UWB systems.
Can I use beacons with Home Assistant?
Yes. Home Assistant’s iBeacon integration can track beacons through Bluetooth adapters and ESP32 proxies, enabling room presence for people or pets carrying a beacon. See our Bluetooth gateways guide for proxies.
How do I track assets in a warehouse?
Attach beacons to assets and place BLE gateways that scan and forward readings to a server or cloud. The gateway’s location tells you which zone each asset is in.
How long do beacon batteries last?
From months to years. Long intervals (e.g. 1 s) and low transmit power maximize battery life, while 100 ms intervals and high power for fast detection can cut it dramatically.
🏁 Final Verdict: Best Bluetooth Beacons
The right beacon for every deployment:
