Home Automation with a low-cost AVR-based Board

Smart Home technology is greatly on the rise. Many manufacturers offer central control units and various actuators and sensors that make it possible to control home appliances remotely via the Internet or smartphones. Unfortunately, such producers mainly use proprietary communication protocols by which the user is bounded to a specific company and therefore the price increases. In general, accessories from different manufacturers cannot be mixed. In this contribution, a solution is presented in which a commercially available 20 evaluation board with the processor ATMega32 serves as the main controller. The provided firmware has been replaced by a web server communicating with the client via REST interface. Two client versions were created: An adaptive web client that makes it possible to determine the actual response using JavaScript and a specific web client for controlling a gas boiler.
