The actual delivered quantity and full packing list are unconfirmed. Confirm the supplied modules, instructions, mounting parts, capacitor, gateway and remote. Pack names and pictured accessories do not establish delivered contents.
The actual delivered quantity and complete contents remain unconfirmed. Pack labels and grouped images are not a verified packing list. Check the modules, instructions, mounting parts, capacitor, remote and any gateway supplied.
No. The exact supplied hardware revision, permitted electrical load, wiring, enclosure fit and UK conformity documents require confirmation. Have a qualified electrician assess the complete installation.
The manufacturer reference describes the RF remote as not included. The selected full packing list and exact transmitter pairing remain unconfirmed; an RF433 label and 1527 reference do not guarantee every remote or carrier-frequency variant.
Bluetooth wording describes the stated pairing workflow and is not proof of standalone Bluetooth control. Confirm the actual wiring, neutral, input frequency, allowed lamp load and safe enclosure. Connected-load power or current must not be presented as the module’s own consumption. Isolate power before work, follow the exact supplied instructions and use a qualified electrician.
