The WiDom devices are designed and manufactured in Italy to be installed in the nodes of the system without modifying it. The systems created with the WiDom devices can also be controlled through new generation interfaces and the use of a regular Internet connection. A WiDom home automation system can be built in stages, with a gradual and modular system. It is possible to start with limited features and then upgrade the system any time new needs arise and/or further budget becomes available. The WiDom devices are the least energy consuming on the market.
