Sonoff used IFA Berlin 2026 to widen its Zigbee smart home catalogue with four new products covering heating, security and home automation: the TRV Gen2 thermostatic radiator valve, a Thermostat Core hub-style controller, the CAM GlassView window-mounted camera, and the SenseGuard Indoor Siren. All four join Sonoff's existing SNZB and TRV product families rather than replacing them, and the company says they interoperate with Apple Home, Amazon Alexa, Google Home, SmartThings and Home Assistant via Zigbee, with prices starting from $24.99. The launch continues Sonoff's push to sell affordable Zigbee hardware that plugs into existing ecosystems rather than requiring its own app, though as with any new Zigbee release, day-one third-party integration quality — particularly on Home Assistant — typically firms up over the weeks after launch rather than at announcement.
What does the Sonoff TRV Gen2 radiator valve do?
The TRV Gen2 is a Zigbee thermostatic radiator valve built for tight spaces behind furniture or curtains, with a compact body, an HD colour display, and local proximity control that lets you adjust it by hand without needing a gateway connected. It supports up to 12 scheduling slots for room-by-room heating routines and includes built-in open-window detection, which pauses heating automatically if it senses a sudden temperature drop from an open window — a feature UK buyers already know from valves like Tado's smart radiator valve.
Does the CAM GlassView work without a Sonoff hub?
Yes — CAM GlassView connects directly over dual-band 2.4GHz/5GHz Wi-Fi rather than needing a separate Zigbee bridge. It's designed to mount magnetically on or near a window, and it can switch between a full 2K resolution and a lower 360P mode depending on how much detail or bandwidth you need. It also supports RTSP and ONVIF, meaning it can be pulled into a self-hosted NVR or Home Assistant camera integration instead of being locked to Sonoff's own app — useful for anyone already running a local recording setup.
How does the SenseGuard Indoor Siren fit into a Sonoff security setup?
SenseGuard is a Zigbee 3.0 siren designed to sit at the centre of a Sonoff security automation, triggering when paired cameras, door and window sensors, presence sensors or water leak detectors detect something unusual. It outputs up to 105dB across 10 selectable alarm tones, with adjustable volume and alarm duration, plus a red visual warning light for silent-alert situations. On its own a Zigbee siren isn't a monitored alarm system, but as an automation trigger inside Home Assistant or SmartThings it's a low-cost way to add an audible layer to a DIY sensor network, provided the rest of the setup already runs through a Zigbee coordinator.
Is Sonoff's IFA 2026 lineup available to buy yet?
Yes — unlike some IFA trade-show reveals that stay concept-only for months, Sonoff says the TRV Gen2, Thermostat Core, CAM GlassView and SenseGuard Indoor Siren are already available to order directly from Sonoff and via Amazon, with prices starting at $24.99 for the entry products in the range. UK buyers should still check individual listings for GB plug/frequency variants and VAT-inclusive pricing before ordering, since global press pricing doesn't always map directly onto the UK storefront.
