Introduction

Collection of different IoT services implemented in golang with the help of gRPC and Protobuf.

The first implemented service allows the control of Philips Hue lights if they are in the same network or if the Philips Hub API is accessible.

Getting Started

# If not yet done create Philips Hue credentials and follow the instructions printed to STDOU
$ go run setup/add-application.go

# Build server and client.
# Install server and client to ${GOPATH}/bin
make all

# Install server and client to ${GOPATH}/bin
make install

# Build and start docker image
make docker-build docker-run

# Clean generate protobuf and binaries
make clean

# Start local server with TLS
go run server/main.go -tls

# Blink lights that are part of group 2 via homecontrol service hosted
# locally.
go run client/main.go -host 127.0.0.1:50051 -tls -cmd blink -group 2

# Dockerized client example with service hosted under 192.168.1.2
docker run -it --rm networld/homecontrol /client -host 192.168.1.2:50051 -cmd blink

# Dockerized client example with service hosted under 192.168.1.2. TLS support
make tls
docker run -it --rm --name homecontrol -v ~/.homecontrol:/.homecontrol networld/homecontrol /client -host 192.168.1.2:50051 -tls -cmd blink
docker exec -it homecontrol /client -tls

Examples: Client

# Change the lights in group 3 to GREEN
$ ./client/client -group 3 -cmd on -brightness 1 -sat 1 -hue 25500

# Change the lights in group 3 to RED
$ ./client/client -group 3 -cmd on -brightness 1 -sat 1 -hue 65535

Features

• TLS encrypted connections
• Lights: Philips Hue support
