The one to reach for once you outgrow back-box modules: 4 independently metered 16A channels (40A combined) on a DIN-rail enclosure that lives in the consumer unit, not behind a switch. That makes it the practical choice for a garage door, an immersion heater, or four zones of a boiler/valve setup on one device. Needs a neutral at each channel and isn't works-with-HA certified (only Shelly's Z-Wave Wave range carries that badge) — but the native local Shelly integration is rock-solid.
