Texting Dryer Gateway

A Raspberry Pi gateway to receive messages from the dryer node.

Pre-Setup

Wire it Up

Enable SPI

For the gateway code to work you must enable SPI on your Raspberry Pi. The easiest way to do that is by running

sudo raspi-config

Select Interfacing Options->SPI and select Yes. Exit raspi-config and reboot.

Quick Start with Docker

The easiest way to get the gateway up and running on the Raspberry Pi is to use the pre-created Docker image.

Install Docker on the Pi

curl -sSL https://get.docker.com | sh
sudo systemctl enable docker
sudo systemctl start docker
sudo usermod -aG docker pi
# Log out and back in to use docker commands

Set Configuration Variables

Modify env.list to contain your Losant credentials and device ID along with the 16 character encryption key to match your RFM69 node. Be sure to uncomment the lines by removing the '#' from each line.

Start the Container

Start a new docker container by running the following from the same directory containing env.list:

docker run --privileged --env-file env.list -ti --restart=always --name rfm_gateway makercrew/texting_dryer_gateway

Running Directly on the Pi

If you prefer not to take the Docker route you can run the code directly on your Pi. You should seriously give the Docker route a try though.

Install Dependencies

sudo apt-get update
sudo apt-get upgrade
sudo apt-get -qy install build-essential \
                         python-pip \
                         python-dev \
                         python-rpi.gpio \
                         git-core

git clone https://github.com/Gadgetoid/py-spidev
cd py-spidev
make install

pip install paho-mqtt
git clone https://github.com/etrombly/RFM69.git

Set Configuration Variables

Modify env.list to contain your Losant credentials and device ID along with the 16 character encryption key to match your RFM69 node. Be sure to uncomment the lines by removing the '#' from each line.

Run the Gateway

sudo python gateway.py

Playing With The Code

Running Directly on the Pi

Simply modify gateway.py and run with:

sudo python gateway.py

NOTE: Be sure you have done all of the prerequisite steps found above for running directly on your Pi.

Building the Docker Image

Modify the code in gateway.py and then re-build the Docker image locally by running:

docker build -t [name of your new image] .

You can now run it in a container with:

docker run --privileged --env-file env.list -ti --restart=always --name rfm_gateway [name of your new image]
