How to Automate and Remotely Control Valves at Home
I remember when I was a kid one of my favorite parts of Disney World was the Carousel of Progress. The fourth act of it showed a ‘futuristic’ world where everything was automated which included a funny interaction with voice activation gone horribly wrong. I always thought that stage was pure science fiction we would never get to see. Well most of it has come true and with most of the kinks worked out.
Automation is now something we all see in our everyday lives. Today we can control our lights thermostats and even our coffee makers automatically or with a simple voice command. One aspect of home automation that has become increasingly popular and practical is the ability to control valves remotely. One area where this automation is making a huge difference is in the control of valves.
Valve automation is the process of controlling valves automatically or remotely to regulate the flow of liquids or gases. This technology once only available in industrial settings is now making its way into our homes offering convenience efficiency and peace of mind.
This guide will cover all the ways you can set up electric control valves as well as how to set them up for various applications. We will break it down into different types of automation integration techniques as follow:
