This article describes the architecture of a home automation system. The system consists of two parts: a centralized one, which represents the solution of linear problems and is a regular service part, and a multi-agent one, marked with a singular service part. To describe the behavior of the elements of the regular service part, the concept of services is introduced. These services are divided into three types: end-user services that directly provide comfort for residents, intermediate services that manage energy storage, and auxiliary services that produce electricity for intermediate and end-users. To solve the problems associated with uncertainty, a three-layer architecture of a multi-agent subsystem is proposed: a local layer, a reactive layer, and a proactive layer. Temporary and permanent services are also designated, and their corresponding subsystem agents are used to describe behavior in reactive and proactive mechanisms. The agents of the reactive mechanism behave in accordance with the stimulus-response process with the possibility of communication. The role of such an agent is to monitor their level of current satisfaction. If the critical level of satisfaction is reached, the agent initializes the start of the messaging process. The basic principle of the proactive mechanism is to divide the problem into independent subtasks. The solution calculates the predicted plan for each subproblem using an annealing simulation algorithm.
