## Description

Model Number: BC021A unique beacon that includes a button trigger AND movement sensorThe button and/or movement sensor can optionally be configured so that beacon only broadcasts for X seconds after button is pressed or beacon is moved (for an alarm or alert-type function). Alternatively, it can broadcast a different UUID after button is pressed or beacon is moved. This feature adds a powerful level of active (button press) or passive (adjustable movement sensing) interaction to the beacon. Transmit distance: 0.2-90 meters Wide Range of TX settings. Long Range BLE 5.0 Shows battery level in broadcast.This unique Multi-Beacon broadcasts your choice of iBeacon, Eddystone TLM, Eddystone URL, and/or Eddystone UID format. Monitor battery level via app.Beacon name, UUID, TX broadcast strength, broadcast interval, major/minor, etc. are customizable via our free apps.Our website has very detailed step by step instructions and screenshots under the Quick Start Guide menu.Specifications: Transmission: iBeacon, Eddystone URL, and/or Eddystone UID format. May be configured to broadcast battery strength.BLE version: 4.0 and 5.0Battery size: CR2032 (included)Battery life: 16 months @ 1second interval & 0dBm & unconnectable modeIncludes 3M double-back tape for affixing to a surface Size: 36mm x 36mm x 5.75mm (approx. 1-7/16" x 1-7/16" x 15/64") Weight: 0.28 ounces including battery Waterproofing: no Password: yes Wide TX Power range: select from -40, -20, -16, -12, -8, -4, 0, +4dBm Interval: adjustable from 100-10,000 milliseconds including optimal precise numbers such as 1022.5ms On/Off switch: yes Movement Sensor: yesChip: nRF52810Transmit distance: 0.2-90 meters Android app: yes iOS app: yes Feel free to contact us if you have any questions or would like to order in bulk.This beacon is compatible with all bluetooth-capable smartphones as well as with our BLE beacon scanning gateway (Item BCG04). Works great with Home Assistant too. See our website for some sample projects using beacons with HA. (Under the "Usage Examples" menu at the top)

Review: 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!
Review: 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

## Questions & Answers

**Q: Can i use this to broadcast Droid [from WDW galaxys egde] BLE codes?**
A: I had to do some deep googling to answer this one! lol

The beacons that make the droids react are non-standard beacons. 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).

*by M***U on 3 March 2022*

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 BC011 and USB versions.
