The make up of a backyard automation system
In reviewing these systems, a number of components can be found that resemble a cross between a computer and an electrical panel, which is essentially what a backyard automation system is. The ‘brain,’ or system processor, houses all of the programming for the entire system, including pre-set data, time clock information, communication with all of the internal components, as well as external products or systems. The system processor also allows smart communication with components that have been built specifically for these control systems.
Connecting the ‘brain’ to the Internet/cloud is probably the most important part in terms of truly automating the backyard. Backyard automation can be done without Internet access; however, these systems operate more efficiently when they are connected. Some systems come with a communication port, where the network cable can be plugged in directly to the controller. A Wi-Fi antenna/bridge can also be used to enable the controller to communicate with the router in the home to access the Internet.
The main electrical components comprise the relays, which enable electrical equipment to be turned on/off, and a breaker panel, where circuit breakers can be installed to distribute power to each of the devices in the backyard. These two components work in tandem to provide power to the electrical equipment. Finally, the power supply is another major electrical component of a backyard automation system.
Sensors are another integral part of the equipment pad, as they allow the system to understand the environment and what needs to be done to control the pool properly. This includes sensors for air and water temperature, as well as sensors which measure the presence of water flow to confirm the heater or chlorinator will work properly and efficiently.
Low-voltage relays and valve actuators are a prime reason controllers are being adopted on high-end pools. These components give the controller the ability to change settings on the valves and to communicate with other devices. For instance, no homeowner wants to go to the equipment pad to switch valves every time they get in/out of their spa/hot tub. The ability to press a button and turn the valves for specific features (e.g. spa/hot tub, water features, or to use low-voltage relays to fire up the heater) are integral to daily pool operation.
Some automation systems even have built-in salt chlorination transformers to eliminate the need for a separate control box when using a salt chlorination cell on the equipment pad. These transformers and connectors make it simple to change the sanitation method—from chlorine to salt—simply by installing the salt cell in the plumbing and plugging it into the automation system. Many systems also have direct connection for pH and oxidation reduction potential (ORP) sensors, which measure water chemistry and balance, and automate the production of chlorine or dispensing of acid depending on these parameters.
