# Aqara Smart Wall Switch H1 EU (With Neutral)

*Aqara / WS-EUK03, WS-EUK04*

> The Aqara Smart Wall Switch H1 EU (With Neutral) (WS-EUK03 single, WS-EUK04 double rocker) needs an Aqara Zigbee 3.0 hub, because it is Zigbee-only. It also needs a neutral wire, in 100-250 V boxes. It suits HomeKit, Google Home and Alexa users through an integration (Zigbee). Home Assistant users reach it through an integration (a Matter bridge).
