*SONOFF / BASIC-ZB1GSP*

> The BASIC-ZB1GSP needs a Zigbee 3.0 hub or coordinator. It is a 32 A DIN rail relay with double-pole switching and energy monitoring, and it also acts as a Zigbee router. It suits Home Assistant users, with native support through Zigbee. HomeKit users reach it through an integration (a Matter bridge).
