| UK installation and delivered contents | Confirm the exact supplied build, wiring, wallbox fit and packing list before ordering. |
Confirm whether the selection supplies a master or transmitter and confirm actual quantity, receiver, battery, mounting parts and instructions. A separately selectable transmitter is not proof that a master is included or that devices are already paired.
UK installation suitability is unconfirmed. Check the exact supplied model, wiring diagram, wallbox space, electrical rating and conformity; regional names or voltage alone do not establish suitability.

Not automatically. App multi-control or RF secondary control is different from conventional traveller-wire switching. Confirm model-specific wiring and pairing instructions; do not assume cross-model replacement compatibility.
The documented wired master requires a neutral conductor and supports 2.4 GHz Wi-Fi and RF control. The wall transmitter has no independent Wi-Fi function and does not replace the wired load-controlling master. Do not apply mains input or lamp-load values to a transmitter. The 1- and 2-gang transmitter SKU suffixes require confirmation. Pairing needs the appropriate receiver, encoding and instructions; matching RF frequency does not prove universal compatibility or pre-pairing. Actual supplied wiring/build, mounting box and clearance, revision, conformity and UK installation suitability unconfirmed; regional names and voltage ranges alone do not establish suitability. Follow the supplied instructions, isolate the circuit supply and verify power is off before wiring; use a qualified electrician when unsure.
