Review: Works perfect! Using these to track when my vehicle arrives home and open the correct garage door. - Small, easy to "install" (double sided tape) and relatively inconspicuous for my purpose. I'm using this to automatically open my garage door when I get close and to reload a device driver in Home Assistant. My scenario: my garage door openers are fairly old (15+ years) and while they do work great, one of them has trouble receiving signal from my Homelink opener in my car. (I almost have to smash the car into the door to get it to open!) Our usual routine included me getting right up on (and I do mean RIGHT up on) the door, opening the OTHER door and going inside to open the door from the other side to my wife opening her mouth (oddly enough, that worked!) I suspect it's her retainer vibrating at the perfect frequency, similar to how Lucille Ball claimed she was picking up CIA radio traffic in her teeth fillings. Obviously, nowhere near ideal. The idea was to use a tracker of some sort, and during my research I found that you want an iBeacon type tracker (which this one is) that can be "programmed" so to speak (broadcast frequency, name, etc.) To integrate this with Home Assistant, you'll need an ESP32 running ESPHome as a BLE tracker/bluetooth proxy. You'll need the MAC address of this device (when you set it up through the app, you'll be able to find it) and define that in your ESP32; that way it doesn't just track every device around that's bluetooth. You'll set a minimum RSSI (received signal strength indicator) so that you don't get false triggers and a minimum time for the device to have lost connection so you don't get false openings. Oh and be sure to give it a name, sometimes Home Assistant/BLE tracker will reject items without a name. You'll need to have your garage door controlled by Home Assistant too, of course. I have a generic Tuya wifi dual-switch garage opener (since I have two doors; it's an older house.) When you leave you manually open (and close) the garage door of course, but the tracker will lose signal to the ESP32. Once it comes back into range ( i.e. it receives a minimum RSSI signal strength you defined before) it will trigger your garage door to open (through an automation you create in Home Assistant.) Mine also reloads an integration I have with my WiCAN pro device, ensuring my WiCAN connects to the garage wifi and updating the fuel/odometer/voltage levels in Home Assistant. If you're not sure how to set this up - ask AI! Seriously, use Gemini, Claude, ChatGPT - they can all help you with it. I did and mine works like a charm. Now when I pull through my gates (I live out in the country, we have gates around the property) my garage door starts opening before I even get near it. I don't even have to bother with my Homelink button other than to open my gates. This thing is small (little bigger than a quarter, and square-ish) so I just double-sided sticky-taped it to the underside of my control console on the ceiling of each of my vehicles. Best part is, since I have two - it can differentiate which door to open! If you just have one door it makes it even easier, but mine opens the correct door when we arrive. The ONLY thing is probably battery life - in order for mine to work the way it does, I have to set the beacon to broadcast twice a second, otherwise I'd be sitting at my door waiting for it to open and I may be where the antenna on the ESP32 can't see it. That means battery life is most likely going to be 6 months to a year (if I'm lucky.) You could probably make an external battery setup (like a pair of lithium AAA's) and that would last multiple years, but these little coin cells don't last all that long. I won't take a point off of for that, as it's just part of the design for it being small. Speaking of - make sure your ESP32 can sit outside for this; my garage faces the side of the house and I have a window facing the street, so I put it there, that way the trackers can be seen inside or out easily. An external antenna on the ESP32 is helpful too. NOTE: other non "iBeacon" types will depend on either Apple or Google for their tracking, and will have severe delays compared to this as they depend on a cloud service AND your phone connectivity. I tried this before and while it would sometimes work, it was very unreliable and when it did, would take forever to actually open the door. I'm halfway to my garage door and it's almost fully open with these AND they are fully local so no cloud service to depend on. Save the other trackers for things like your luggage or keys. I think you can even use these to triangulate a location by using multiple ESP32's too, but I haven't had a need to do that yet.
Review: As described and mentioned. - Excellent product, install KBeacon app and you have the option to change the configure, much more options to configure than tile.

## Questions & Answers

**Q: can i make this beacon connectable with my android phone so I can use it as the smart lock trusted device feature on my phone?**
A: As far as I know, no, you can’t use a beacon as a smart lock trusted device. Why not? Because smart lock works with a connection to a Bluetooth device, e.g. a device such as headphones. When the device is present AND connected to your phone, your phone will stay unlocked. Beacons, on the other hand, do not connect to your phone ever, unless you are configuring them (which you usually will only do once in the lifetime of the beacon).

One idea: I can’t guarantee it, but I think one of those “lost keys/luggage” devices would work. I’m definitely not sure about this though, so do some more research first.

**Q: Can you use it to send a url?**
A: Yes, but you should note that beacons can not cause  messages to appear on nearby phones unless those phones have your app installed. Without an app, beacons broadcasting URLs will have no effect on nearby phones. If you are reading articles that say this is possible, those articles are two years out of date.

**Q: Could these be set up to track employees leaving and entering the building in lieu of clocking in?**
A: Sure, that's one of the most common uses for beacons. Quite a few medical facilities are adding this feature to keep track of doctors, nurses, PAs, etc. and how much time they spend in each treatment room, etc. In this scenario, the employee would carry the beacon with them. 

The main challenge will be for you to set up a scanner to scan for known beacons and to log the time that they enter and then later exit. This type of hardware is called a gateway, e.g. BLE gateway. Gateways are not cheap and require some tech skills to set up, but it's all doable if you invest some time in learning the basics. Another much cheaper option is to make a DIY gateway using a programmable module such as a ESP32 or similar. 

You can contact me anytime on the Blue Charm website if you would like more info about this topic.

**Q: Can you recommend a usb ble 5.0 dongle to reading these beacons?**
A: Wish I had a good answer for this one, but I have not spent any time working with BLE dongles yet. 

One thing to be careful of: There are many many Bluetooth dongles on Amazon, but nearly all of them are for connecting a bluetooth keyboard to your computer (or headphones to your computer or similar type of application). These will NOT read beacons. What you need is a BLE dongle specifically for reading/scanning beacons.

### ⭐⭐ Problem connects to app
*by R***N on 29 September 2026*

I don't know what this beacon capable of, and the kbeacon app detected this, but shown error when tried to connect it. so not exactly know what this beacon capable of. my use case is too simple and I'm just using this as a dump beacon only. so as long as the ble receiver able to read its signal, the beacon is working for me. This thing is considered expensive with regarded as a dump beacon in my use case. let see how long this device can last. The beacon comes with a cr2032 preinstalled though. nothing to install for my use case.
