Last checked: 19 July 2026. Use this research-led checklist before buying. Smart Home UK has not physically tested every device listed elsewhere on the site.
1. Identify the exact product
Record model number, generation, UK voltage/plug, fitting, firmware and seller. A brand name alone is not a compatibility check.
2. Identify the control roles
- Matter: confirm device class, Matter version and compatible controller.
- Thread: confirm a Thread border router as well as a Matter controller.
- Zigbee: confirm the coordinator/bridge and exact device support.
- Wi-Fi: confirm band, account/cloud requirement and local behaviour.
3. Check the physical system
For heating, record boiler, hot-water and wiring layout. For lighting, record B22/E27/GU10 and dimmer/switch arrangement. For cameras/doorbells, record power, transformer, storage and subscription. For plugs/switches, record load and fixed-wiring requirements.
4. Check the household ecosystem
Verify the exact Apple Home, Alexa, Google Home, SmartThings, Home Assistant or vendor-hub support and which features are exposed. “Works with” does not mean every feature is local or available across platforms.
5. Record failure and recovery
Document what works without internet, account recovery, household access, manual controls, update support, warranty and data deletion.
Where safety or fixed wiring is involved, follow current manufacturer instructions and use someone competent and suitably qualified.
