I believe automation can play an useful role in helping to reduce energy consumption. For example being able to control my home central heating system remotely enables me to only turn on the heating when it’s required and not have it running on a set schedule when the house is empty.
As previously mentioned in a blog post, the emonPi (running emonSD pre-built SD card) can function as a powerful home automation hub. Utilising the emonPi as a home automation hub is a good fit for a number of reasons:
- It’s already running 24/7 for energy monitoring
- It’s optimised for robust long term operation: the root Raspberry Pi file-system is read-only to increase SD card lifespan
- It’s already connected to your local network
- It’s running Debian Raspbian Jessie therefore installing extra packages is easy and lots of support is available
- Raspberry Pi 3 has plenty of space capacity
- Extra radios / accessories can be connected via USB
- It’s already running an MQTT server
- emonSD pre-built SD card comes pre loaded with the following integrations nodeRED, OpenHAB and LightWaveRF
In this post I want to share with you how I use the emonPi in my own home.
Here is a video demo using Google Home to control my central heating and devices via MQTT:
