For years, the smart home revolution has largely bypassed one of the most common forms of home heating: traditional radiators and localized radiant systems. While countless consumers have outfitted their properties with advanced smart thermostats designed to seamlessly integrate with central hubs and forced-air heating and cooling networks, those relying on alternative methods have been left with limited or non-existent options. That glaring industry gap, however, finally appeared to narrow at IFA 2026, where smart home manufacturer Sonoff introduced a suite of innovative heating alternatives tailored specifically for properties using traditional radiators and underfloor systems.
The centerpiece of Sonoff’s announcement is its latest TRV Smart Thermostatic Radiator Valve. Designed to bridge the technological divide between legacy infrastructure and modern automation, the device is engineered to fit directly onto the valve pipe of a traditional home radiator. Users can simply screw the unit into place, connect it to their home Wi-Fi network, and immediately gain access to detailed app insights and a comprehensive suite of remote control options. Available currently through the official Sonoff website for $35, the smart valve supports both Celsius and Fahrenheit temperature measurements, making it a versatile addition to international markets where radiant heating remains standard.
Finding up-to-date smart radiator solutions has historically proven challenging, particularly for consumers in regions where forced-air systems dominate. Sonoff’s new hardware changes that dynamic by allowing users to effortlessly adjust between multiple customized temperature plans. The device features a vibrant IPS color screen that clearly displays current temperatures and operational settings at a glance. Furthermore, the companion mobile application delivers critical operational notifications, including low-battery alerts that prompt recharging, frost protection reminders, and anti-calcification maintenance alerts.
Adding to its utility, the valve integrates smoothly with auxiliary hardware such as window sensors. When a window is opened, the system can automatically halt heating to prevent energy waste. It also includes a built-in child lock designed to prevent little hands from unintentionally altering established heating schedules. This combination of targeted features directly addresses the needs of residents living in homes that rely primarily on radiators, properties that combine radiators with central heating, or spaces where radiators are isolated in specific areas, such as finished basements. By deploying these units, homeowners and renters can unlock the same energy savings potential and daily convenience long associated with standard smart thermostats, coupled with features engineered exclusively for radiator architecture.
Are you more of a radiant floor heat home? Sonoff has you covered, too
Beyond traditional radiators, many contemporary properties rely on an entirely different method of climate control: radiant floor heating. Frequently installed in bathrooms, kitchens, and homes featuring specific types of wood or tile flooring, radiant floor systems offer a distinct heating experience that standard thermostats cannot directly manage. Recognizing this market segment, Sonoff used the IFA 2026 stage to unveil a dedicated solution for hydronic underfloor heating configurations.
The company announced its new Thermostat Core, a device purpose-built to fit standard hydronic underfloor heating systems. The hardware introduces full mobile app controls, robust scheduling capabilities, and seamless integration with Sonoff temperature sensors. By pairing the core with localized sensors, floor heating systems can intelligently respond to the exact ambient temperature of a specific room rather than relying on a generalized household reading. Similar to the radiator valve, the Thermostat Core incorporates a presence-activated screen, comprehensive frost protection protocols, and advanced system synergies designed to maximize overall energy efficiency.
While official pricing details for the Thermostat Core were not immediately released during the exhibition, the announcement signals a broader industry shift toward comprehensive climate management. Sonoff’s expanded lineup indicates that manufacturers are beginning to look beyond central forced-air systems to address the diverse infrastructural realities of global housing markets.
Alongside its new heating hardware, Sonoff used the trade show to showcase several additional smart home products intended to expand its ecosystem. Among the notable additions were a new indoor siren and a specialized window security cam. The introduction of a window-mounted camera places Sonoff alongside competitors like Eufy, which also highlighted a window camera ecosystem at IFA, and Wyze, which released its own window-focused security model earlier in the year. These specialized cameras are engineered to mount directly onto glass surfaces, offering a discreet surveillance option that proves especially useful for apartment dwellers and renters who face installation restrictions. Through these diverse hardware introductions, Sonoff aims to solidify its footprint in both home climate control and residential security.
