About the project
Monitor your doors and windows with a Shelly low-power BLE sensor, combined with a Particle Photon 2.

Items used in this project
Story
This project reads the Bluetooth advertisements from the Shelly BLU Door/Window sensor using a Particle Photon 2.
These sensors can be used with a Particle Argon, Boron, or Monitor One. In fact, any Particle device with BLE will work.
Shelly BLU Door/Window sensor
This sensor detects and reports the opening or closing of doors and windows, measures tilt angle, and monitors luminosity. It advertises this data in the BTHome format.
For this project the Shelly sensors were configured with the Beacon mode on. In this mode the device broadcasts the current open/closed state, illuminance, and battery status every 30 seconds.
It is suggested to update the Shelly devices to the latest firmware with the Shelly app.
In case of trouble one can use the Shelly debug app.
Particle Photon 2
This powerful Wi-Fi microcontroller from Particle continuously scans for nearby Shelly sensors.
For the longest range, add an external BLE antenna (and enable it in the code).
Code
The Particle beacon-scanner library was updated as part of this project to detect BTHome devices.
The minimal code to scan and get information from these devices is on GitHub.
Here's the output of a couple of sensors detected by the Photon 2:
