The original listing offers Zigbee mini light-switch modules in two options: ZM-104-M-MS for 1 gang and ZM-104B-M-MS for 2 gang. MOES has public documentation for the corresponding older base model names, but its current product page and linked manual use a different LT version. Those newer specifications are not bound to these listed SKUs.
The original listing requires a Zigbee gateway, purchased separately. Confirm the exact module label, compatible gateway, supplied manual and wiring requirements before installation. Rocker-switch support, relay-memory behaviour and multi-control functions remain version-dependent and are not a promise of compatibility with every switch or circuit.
The original listing states a 10 A total current limit. Do not add the gang ratings to infer a 20 A total rating for the 2 gang option. The exact load category, electrical rating and UK suitability still require confirmation for the supplied version.
