The `eddystone_temperature` sensor platform reads temperature information from Bluetooth LE advertisements transmitted by [Eddystone](https://en.wikipedia.org/wiki/Eddystone_(Google)) beacons. Your beacons must be configured to transmit UID frames (for identification) and TLM frames (for temperature).
|
|
All beacons that support the Eddystone protocol, have a temperature sensor and can transmit TLM frames are compatible with this platform. For example [Gimbal](https://store.gimbal.com/collections/beacons/), [Estimote](http://estimote.com/) or [kontakt.io](https://kontakt.io/). For more manufacturers see [this overview](https://developers.google.com/beacons/eddystone#beacon_manufacturers) by Google.

## Requirements
|
|
|
|
As this platform uses `bluez` to scan for Bluetooth LE devices **a Linux OS with bluez installed** is required. In addition to that, the `libbluetooth` headers need to be installed:
|
|
|
|
```bash
|
|
$ sudo apt-get install libbluetooth-dev
|
|
```
|
|
|
|
Scanning for Bluetooth LE devices also requires special permissions. To grant these to the python executable execute the following:
|
|
|
|
```bash
|
|
$ sudo apt-get install libcap2-bin
|
|
$ sudo setcap 'cap_net_raw,cap_net_admin+eip' $(readlink -f $(which python3))
|
|
```
|
|
|
|
To use your Eddystone beacon in your installation, add the following to your `configuration.yaml` file:
|
|
|
|
```yaml
|
|
# Example configuration.yaml entry
|
|
sensor:
|
|
- platform: eddystone_temperature
|
|
bt_device_id: 0 # optional
|
|
beacons:
|
|
living_room:
|
|
namespace: "112233445566778899AA"
|
|
instance: "000000000001"
|
|
kitchen:
|
|
namespace: "112233445566778899AA"
|
|
instance: "000000000002"
|
|
```
|
|
Configuration variables:
|
|
- **bt_device_id** (*Optional*): The id of the Bluetooth device that should be used for scanning (hci*X*). You can find the correct one using `hcitool dev` (default: 0).
|
|
- **beacons** array (*Required*): The beacons that should be monitored.
|
|
- **[entry]** (*Required*): Name of the beacon.
|
|
- **namespace** (*Required*): Namespace ID of the beacon in hexadecimal notation. Must be exactly 20 characters (10 bytes) long.
|
|
- **instance** (*Required*): Instance ID of the beacon in hexadecimal notation. Must be exactly 12 characters (6 bytes) long.
|
|
- **name** (*Optional*): Friendly name of the beacon.
