Code for home automation projects. Central comms is via MQTT, either via wired ethernet or wireless via WiFi.

Overall Configuration

All projects attempt to be general purpose and able to be installed onto multiple devices on the same network. To do this each unit includes some form of unique ID in their communications. Many also include a user configurable string, normally configured via MQTT.

Network configuration is included at compile-time by including a common header file <Secrets.h> installed as a library.

EmonCMS installed on a Raspberry Pi2 MQTTWarn used to pull messages from MQTT and feed into EmonCMS

Power Monitoring

emon_cont_direct/emon_cont_direct.ino

EtherTen Arduino clone with a openenergy.org EmonTX Shield V2. This has been modified from stock with the following changes:

• Ch4 rerouted to Analog pin 6. This is so the on-board MAC address chip can be addressed via I2C
• Burden resistors on Ch2 & Ch4 changed to 180ohm to improve sensitivity. These are used for monitoring a heat pump and house lights.
