Aqara Smart Wall Switch H1 EU (No Neutral) - Double vs Aqara Smart Wall Switch (With Neutral) - Single

The Aqara Smart Wall Switch (With Neutral) - Single packs in more built-in safety protection and energy monitoring than the Aqara Smart Wall Switch H1 EU (No Neutral) - Double, though the two switches were built to solve opposite wiring problems. The With Neutral Single model needs a neutral conductor in the box and only switches one circuit, in exchange for energy monitoring, overheating and overpower protection built into its WS-USC03 body. The H1 EU (No Neutral) Double, meanwhile, controls two separate circuits from one plate without needing a neutral wire at all, and pairs a higher owner rating with a typically lower price than the single-gang model. Both connect over Zigbee through a hub and reach the same lineup of Google Home, Alexa, Apple HomeKit, Home Assistant, IFTTT and Matter. If your box has a neutral wire and you only need to switch one circuit, energy tracking makes the Aqara Smart Wall Switch (With Neutral) - Single worth it; if you're wiring two circuits from a box with no neutral, the Aqara Smart Wall Switch H1 EU (No Neutral) - Double is the only one of the two that will even work.
