How Reliable is a Home Automation System?

A basic Home Automation system will send a command out and hope it is actioned (like pressing a button on a TV remote control) whilst more complex systems will send a command and await a response, for example a serial command to a TV will be “TV on” and then a command back from the TV – “OK TV on”. Different actions can be performed if a response is not forthcoming – a warning on a user interface or power cycling the TV for example. Generally the more complex the Home Automation the higher the cost and the more specialist the installation.
