X-10 is a home automation standard that developed in the 1980-90s, however, it remains a cheap and simple system that can be used today. 

However, we have discontinued using X-10 and migrated to smart devices using the Zigbee protocol.  I am leaving these pages here for information and reference.

The following pages explain the:

• Types of X-10 modules available
• Photos of X-10 modules
• Uses of X-10 modules

A separate main menu link provides technical details on how I have modified 115V USA X-10 modules to operate at the UK's 230V.

Here the different types of device that have been used are explained: these are:

• Transceiver units that both transmit and receive X-10 control signals.
• Computer interfaces that allow a computer to control and monitor your X-10 System.
• Mini and maxi controllers to control devices manually.
• Appliance modules that just switch on and off.
• Lamp modules that allow dimming.
• Various sensors.

When our property was built in 1989, we had a Southern Electric Electratech System installed, which used impulse relays in the consumer unit. 

However, this system was hopelessly unreliable, and Southern Electric paid to replace it with X-10 modules, passing future maintenance and repair responsibility onto us, which we accepted.

Here I show photographs of our X-10 system as currently installed, including: 

• The fuse box with DIN appliance and Powerflash modules.
• The Study where the computer interfaces are.
• Transceiver units, located in a central area.
• Appliance modules controlling irrigation
• Stanley motion detector
• A talking motion detector

The USA has a cheaper and richer source of modules than the UK has.  A mix of USA and UK modules that are used in our installation are explained and the specific uses are described:

• Transceiver Units
• Computer Interfaces
• The Maxi-Controller
• Storage Heater Control
• Convector Heater
• Lighting
• Misc Uses
