Blue Charm Beacons - Bluetooth BLE iBeacon (BC021-MultiBeacon) with Movement Sensor - Long Range BLE 5.0

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.

First, it works -- compared to the cost of competitors and for what you get, it's a great value. The downside (or possible upside) is that this is more of an Open Source eco-system whereas the other brand-specific Beacons tie you to their curated ecosystem, so this one is more flexible, but won't have the best utility UI/polish. You can use the iOS/Android software to set it up as you want (not the most friendly, but you can figure it out, I believe in you). With Android, you can use Tasker/etc. to trigger all sorts of things -- for my use case, I have it trigger a specific Tasker profile when I'm near an Android tablet so I can get that Tony Stark feeling when I walk into a room. Unfortunately; and this has nothing to do with this particular beacon; for those looking to do similar stuff with Windows .. it's not as easy. For some reason, Microsoft is really behind in Beacon support, they still treat them like normal Bluetooth devices, and the 3rd party apps just scan for them. Meaning that try as I might, I could not trigger any script when the presence (passive support) of a Beacon was detected, as Windows really wants for you to connect to it beforehand and you don't want to do that in most cases. Not sure if Win11 has introduced any improvements, but one could hope they catch up so we can use them as dynamic lock devices.

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!

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

Bought this to track keys for an occupancy sensor in ESPresense. Out of the box it already transmits iBeacon so didn't even need to download the app to configure. Had it running for a few days and it's been working great and consistent. UPDATE: I bought a second one of these. Turns out that out of the box they give off the exact same iBeacon IDs as each other. I debated taking a star off for this but it was easy enough to alter the ID using their app. I still really like it so keeping the 5 stars but this should be known by others.

These beacons are easy to set up and have great range. I’ve used them over several months for cresting proof-of-concept apps, and the batteries have held well above 95% the whole time.
