Sonoff's new smart heating and security devices signal a shift towards more integrated, local control systems at IFA 2026

Sonoff has unveiled a range of new products at IFA Berlin, including radiator valves, hydronic underfloor controllers, and cameras, aiming to boost local control and ecosystem integration in smart homes beyond traditional cloud-dependent devices.

SONOFF used IFA Berlin to do more than add another smart plug or light switch to its catalogue. The company has pushed into two areas that many mass-market smart-home brands still treat poorly: radiator heating and hydronic underfloor systems. As of Saturday 5 September 2026, three of the four new products shown in Berlin , the TRV Gen2 radiator valve, CAM GlassView camera and SenseGuard indoor siren , have live store listings and prices, while the Thermostat Core is listed on SONOFF’s own shop as a pre-order item through 28 September, with UK and EU shipments expected from 30 September. That current position is narrower than some early coverage suggesting the whole range was already available immediately. (smarthomeassistant.co.uk)

That matters because SONOFF is pitching these devices not as a separate closed system, but as additions to an existing mixed-protocol installation. Smart Home Assistant reported that the new releases join the company’s SNZB and TRV families rather than replacing them, while Gear Diary described the wider IFA showing as part of a move from isolated gadgets towards a more connected home. SONOFF says the broader ecosystem spans Matter, Zigbee, Z-Wave and Wi-Fi, with integration across Apple Home, Amazon Alexa, Google Home, SmartThings and Home Assistant via eWeLink scenes and automations.

The strongest part of the launch is arguably heating, especially for European homes that do not rely on forced-air systems. News4Daily noted that most smart thermostats are built around central forced-air heating and cooling, making radiator and radiant-floor households an awkward fit. SONOFF’s answer starts with the TRV Gen2, a room-by-room Zigbee radiator valve that the company says is 38% smaller than the earlier model, fits standard M30 x 1.5mm valves and runs on two AA batteries. The valve supports up to three weekly heating plans with as many as 12 periods per day, can pause heating when a window is opened, and adds safeguards such as frost protection, anti-calcification and child lock. SONOFF’s store also says users can view up to six months of target temperature, current temperature and heating-activity history. (news4daily.com)

The Thermostat Core extends that strategy to hydronic underfloor heating and boilers. According to SONOFF’s current product page, it combines a powered output of up to 3A for heating actuators with a dry-contact output for boiler control, offers three switchable schedules with 12 daily segments, and can use an external 10KΩ NTC sensor to prevent floor overheating. A presence sensor wakes the display as someone approaches, and SONOFF says historical data is stored for up to six months. There is also a compatibility warning for advanced users: the company says Zigbee2MQTT 2.14.0 or later is required, and that native ZHA support was still awaiting merger via pull request #5201, so some Home Assistant setups may need manual configuration. Gear Diary said pricing had not yet been announced on 4 September, but SONOFF’s own shop now shows a discounted pre-order price of $35.91, down from $39.90. (geardiary.com)

The CAM GlassView takes a different route from a normal outdoor security camera. Instead of drilling through an outside wall, SONOFF mounts the 3MP, 2K camera against the inside of a window with 3M adhesive, then relies on an anti-glare algorithm, dual-band Wi-Fi and local recording to make the approach practical. The company says the camera supports 2.4GHz and 5GHz Wi-Fi, RTSP and ONVIF for NVR or Home Assistant use, a browser-based OpenEdge console, and storage on a microSD card of up to 128GB without a subscription. Scargill’s Tech Blog found the setup process straightforward, noting that the device creates a Sonoff_S3W-xxx hotspot during pairing and can then be managed directly through its IP address in a browser. The same hands-on report also observed that the camera has no infrared light, which could help a window-mounted design avoid the night-time reflections that made older indoor-facing cameras less useful.

Even so, the GlassView is not being treated as a perfect fit for every security job. SmarterKram argued that 5GHz support is unusually strong at a launch price of €34.90, particularly for Home Assistant and Frigate users looking for local-first hardware. But the same review questioned whether the camera’s human-detection functions remain fully local when the device is offline, and pointed out that Wi-Fi-only networking without PoE will count against it in more security-focused installations. Scargill’s early test was also measured rather than glowing, noting that only one extra sensor appeared alongside the video feed in Home Assistant. (smarterkram.de)

The SenseGuard indoor siren is less flashy, but it may be the most useful part of the package for DIY security systems. SONOFF says the Zigbee 3.0 device can sound at up to 105dB, offers four volume levels, 10 preset tones, independent sound and light alarms, and a rechargeable 600mAh backup battery that can keep it online for more than 300 days in silent standby. DomotiCasa reported that Zigbee2MQTT already exposes controls for siren activation, light and sound enablement, tone selection, volume, duration, battery state, power-supply mode and tamper status. That same report, echoing SONOFF’s own product page, said native ZHA support was still incomplete pending pull request #5136. In practice, that means the siren is well aligned with hobbyist platforms, but not yet equally polished across every Home Assistant route on day one. (geardiary.com)

Around those four launches, SONOFF used its IFA stand to show how it wants to sell an entire automation stack rather than a few disconnected endpoints. Gear Diary and AndroidGuys both listed the NSPanel Pro Gen2, Bridge Max Matter Bridge, Z-Wave 800 PoE Dongle Max, SenseGuard Presence Core, Hydro Duo Smart Water Valve, S61S outdoor smart plug, TX Gen2 wall switch and a DIN-rail smart switch among the wider display. The logic is straightforward: leak sensors can shut off water, presence sensing can trim heating when rooms are empty, and a camera or contact sensor can trigger an audible siren. For buyers comparing ecosystems, the more notable point is that SONOFF is trying to pair low prices with local control hooks, rather than forcing every workflow back through a proprietary cloud app. (geardiary.com)
