Visualisation of heating control process for home automation

Current available commercial products for visualisation are either a very simple or complex and expensive solutions. This paper deal with a problem of heating control process visualisation in a family house. A development of modular, cheap and extendable solution is described in several steps. The communication between the regulator module and the computer where visualisation is realised is built on the basis of RS232 protocol using Bluetooth technology. The application was established in a development environment SharpDevelop which is free of cost. Developed solution is suitable for home usage where a various heating technologies is used without any comfortable visualisation option.
