Intro

Apogee Connect for Raspberry Pi is a lightweight script intended for automating the data collection process with Apogee's Bluetooth sensors.

Apogee Connect can be used in two different ways:

1. As a standalone command line application with straightforward commands for interacting with Apogee's Bluetooth sensors.

2. As a Python module for those looking to implement the application functionality directly into their own Python script.

Prerequisite

In order to install, you will need pip (the package installer for Python). Pip is likely already included by default on a Raspberry Pi or if Python was installed from source. You can confirm pip is installed by running the command:

pip --version

If pip isn't already installed, visit the following site for instructions on a simple pip installation:

https://pip.pypa.io/en/stable/installation/

Command Line Application

Installation

Install

1. We will use pipx, which is a tool that runs Python modules as a standalone command line application. In terminal, run the following command (It may be necessary to close and restart the terminal after installing pipx for it to be recognized):

sudo apt install pipx

2. Install Apogee Connect for Raspberry Pi from the Python Package Index by running the following command in terminal:

pipx install apogee-connect-rpi

3. Add the install location to your PATH environment variables so that it can be run from anywhere in the terminal.

pipx ensurepath

4. Verify installation by running the following command (It may be necessary to close and restart the terminal first for the changes to take effect):

apogee --version

Update

To update to the latest version, run the following command in terminal:

pipx upgrade apogee-connect-rpi

Uninstall

To uninstall, run the following command in terminal:

pipx uninstall apogee-connect-rpi

Basic Example

Note: apogee is the command that can be run from the terminal at any location to use the app.

1. Scan for nearby Apogee sensors to obtain sensor's MAC address required for connection.

apogee scan

2. Start collecting data from the sensor with the MAC address of AA:BB:CC:DD:EE:FF and set a logging interval of 10 minutes.

apogee collect AA:BB:CC:DD:EE:FF --interval 10

3. See a list of all currently collecting sensors along with the number of logs currently collected, data file location, start/end time, etc.

apogee list

4. Stop data collection from the sensor with the MAC address of AA:BB:CC:DD:EE:FF, but not until the epoch timestamp of 1726247820 (Unix timestamp in seconds).

apogee stop AA:BB:CC:DD:EE:FF --end 1726247820

Commands

Key:

apogee command <required_argument> [--optional_arguments (default: value)]

collect

Usage

Collect data from an Apogee sensor and write the data to a csv file.

Automatic collection is the default collection mode, which will turn the sensor's logging on and then automatically collect all available data and record it in a csv file. The frequency with which the Raspberry Pi will "wake up" and check for available data from all sensors can be adjusted through the config command.

If a manual collection mode is needed, add the --manual flag to the command. If the sensor is not listed as currently collecting (see list command), this will turn the sensor's logging on with the included interval, start/end time, etc. If the sensor is already listed as collecting, it will collect available data from the sensor and add it to the csv file (when collecting data, the --file argument can be included to store the data in a different file than what was originally set but --interval, --start, and --end will be ignored).

Example

apogee collect D7:52:21:95:5C:6C --interval 10 --start 1720647720 --end 1721250915 --file /usr/Documents/greenhouse-data.csv

apogee collect D7:52:21:95:5C:6C --interval 10 --file /usr/Documents/greenhouse-data.csv --manual

Functions

collect

Usage

Collect data from an Apogee sensor and write the data to a csv file.

Automatic collection is the default collection mode, which will turn the sensor's logging on and then automatically collect all available data and record it in a csv file. The frequency with which the Raspberry Pi will "wake up" and check for available data from all sensors can be adjusted through the config function.

If a manual collection mode is needed, set the manual argument to True. If the sensor is not listed as currently collecting (see list function), this will turn the sensor's logging on with the included interval, start/end time, etc. If the sensor is already listed as collecting, it will collect available data from the sensor and add it to the csv file (when collecting data, the file argument can be included to store the data in a different file than what was originally set but interval, start, and end will be ignored).

from apogee_connect_rpi import ApogeeConnect
