Wi-Fi heating controls and timers

Wi-Fi heating controls and timers allow remote control and scheduling of domestic central heating systems and electrical heating accessories using a smartphone app or web interface. This category includes Wi-Fi room thermostats, plug-in Wi-Fi timers, and connected control devices designed to provide flexible scheduling, remote access, and real-time control.

Products are listed with clear specifications to help identify suitable options based on system compatibility, operating voltage (typically 230V AC), connection type (wired or plug-in), and control features such as scheduling modes and remote access functions. Installation and operating instructions are available via our product instruction library.
