BLE Battery Recorder

This is a Windows background service which periodically records the battery levels of Bluetooth devices. It runs in the background and logs battery levels to C:\ProgramData\BLE Battery Recorder\battery.csv every 10 minutes.

Setup

Install the following:

Clone this repo:

git clone https://github.com/joelspadin/BleBatteryRecorder.git

To install the Windows service, open a terminal as administrator and navigate to the directory containing the .csproj file, then run the Install.ps1 script:

cd BleBatteryRecorder/BleBatteryRecorder
./Install.ps1

To remove the service, run Uninstall.ps1.

Alternatively, this program can be run as a standard console application. The log file is then written to the current directory instead of to C:\ProgramData.

cd BleBatteryRecorder/BleBatteryRecorder
dotnet run

Graphing Results

Results are written to a CSV file. To display them as a graph, open a terminal and navigate to the directory containing the .csproj file.

Optionally, create a virtual environment to avoid installing dependencies globally:

python -m venv .venv
.venv\Scripts\Activate.ps1

Next, install the dependencies:

pip install -r requirements.txt

Then run the graph.py script. You can provide a path to a CSV file as the first argument if you want to graph a different file.

./graph.py
