Blue Charm Beacons Bluetooth BLE iBeacon BC011-MultiBeacon with Button Trigger.

These Blue Charm beacons do exactly what they say they do. They were easy to set up, easy to program, and simple to attach to keys or place where needed. The app gives you access to useful settings like the beacon name, measured power, power profile, firmware updates, and different broadcast options depending on what your compatible device or system supports. Once configured, other compatible devices can detect them reliably, and they quietly do their job in the background. Overall, they’re a solid little product: easy to configure, easy to carry, and useful for a variety of Bluetooth beacon needs. I’d definitely recommend them.

There are a few reasons to buy a beacon (any beacon actually) from Blue Charm: 1). Not many companies make proximity beacons and sell them piecemeal to lowly consumers who just want 1 or 2 to use them to do weird geofencing projects at home. Most of these big guys like Estimote don't sell individual beacons anymore and they definitely stopped supporting them and updating their apps. There aren't many sellers of proximity beacons an amazon besides BlueCharm actually...or even on the general web. 2) They work. If you're not a techy person, learn the tech and if you're not getting the beacon to work.. It's probably user error. However, if you’re having trouble getting it setup, see #3. 3) This is the biggie. Customer support. I sent a question about a project I was doing (wanted the beacon to track and send webhooks when I was very close to it) and Thomas (the owner) responded within an hour with a very detailed answer. He even got invested in the project I was working on and gave me different scenarios to try that he tested himself for my unique case! Wow. Can't ask for more hands on customer service than that. I'm getting to the bottom of my problem and it's definitely not the hardware beacon itself...it's another software issue that Thomas himself helped me discover. Besides all of this, he's obviously invested in what he's doing and is a good engineer. Definitely the go to choice for buying beacons. Support BlueCharm.

Using these with room assistant to track everything from water bottles to my AirPods. They take a few seconds to update but their ease of setup and configuration options, ability to lock down and replaceable battery means I’ll be using these for quiet some time.

So far, so good. Working well with Home Assistant and tracking if the dogs are in the home/yard. Exactly what I needed.

Arrived with 60% battery life, so they must not sell well. Doesn't sync with their suggested App (KBeaconPro). It showed up once now wont find it again. So far nothing recognizes it. Feeling like a scam at this point. Very disappointed.

Configuration of this beacon is done via a generic android app. I reduced the beacon interval down to 4 seconds. Battery life is greater than a year. It's low profile, and I taped it to a paper card and put it in my wallet. In a pinch if I lose my wallet, I can use the app and scan for it and narrow down the room I lost my wallet in. No, it's not quite like a tile, but it works with open source projects like home assistant.

I bought this beacon after consulting with the BlueCharm Beacon support folks (they responded within a couple of hours of my request) because I wanted to experiment with scanning for beacons from an iOS app using CoreBluetooth as opposed to the Beacon APIs in CoreLocation. Since iBeacons aren't normally detectable using CoreBluetooth, I needed a beacon that could advertise in other formats, such as Eddystone. I was able to successfully scan for Eddystone UID and TLM payloads (I'll provide BlueCharm with the details so you can likely ask them directly about this if you are interested). The suggested KBeacon iOS app worked flawlessly for configuring the beacon. I was able to use it to change the UID/TLM payloads and then see those custom values in the advertising data when scanning with CoreBluetooth! Throughout this, BlueCharm support was very helpful and responsive to all of my questions. Thanks again!

Using several of these to track objects within Home Assistant. This beacon broadcasts with MQTT and can be utilized to track and locate these items throughout my home. Previously, I utilized Tiles and there is no comparison! These feel more solid, have a replaceable battery, and are customizable in many different ways (UUID, RSSI @1m, etc). Also, Thomas (owner of Blue Charm) has been extremely helpful explaining the features and technologies within the devices so that I can make more educated decisions on my project. I've also utilized the BC021 and USB versions. I believe that I'll lean toward the BC021 for future projects, but this was my first and it has been great!

Excellent product, install KBeacon app and you have the option to change the configure, much more options to configure than tile.
