Outcome
This companion comparison post compares Shelly 1 to the top live alternatives found on April 10, 2026, including current Amazon and Alibaba checks.
Source Device
Shelly 1 is a compact Wi-Fi relay with dry contacts designed for switching AC or DC loads. It supports 110-240 VAC or 12-60 VDC power supply, offers Wi-Fi connectivity, and integrates with Home Assistant via an official integration. It's known for its small size, fitting into wall boxes, and low power consumption. The device does not require a hub and supports schedules and webhooks.
Top Alternatives
- Shelly 1 Mini Gen3: The Shelly 1 Mini Gen3 is a direct successor to the Shelly 1, offering a smaller form factor with updated features. It's a Wi-Fi and Bluetooth smart switch relay with dry contacts, supporting both AC (up to 240V) and DC (up to 30V) loads. It integrates seamlessly with Home Assistant, supports scripting, webhooks, MQTT, and can operate without a hub, similar to the original Shelly 1. It also features an improved processor and increased memory, and is Matter certified (after firmware update).
- Zooz ZEN16 MultiRelay: The Zooz ZEN16 is a Z-Wave multi-relay with three dry contact relays, making it suitable for controlling multiple independent loads, similar to how multiple Shelly 1 devices could be used. It supports a wide range of voltages (12-240V loads) and can be powered by USB-C or 12-24V AC/DC. It offers robust local control via a Z-Wave hub and has excellent integration with Home Assistant through Z-Wave JS.
- Sonoff SV (Safe Voltage): The Sonoff SV is a low-voltage Wi-Fi switch with dry contacts, making it a suitable alternative for controlling AC or DC loads. While its default firmware relies on the eWeLink cloud, its open nature and reserved GPIO pins make it highly attractive for DIY enthusiasts who want to flash custom firmware like ESPHome or Tasmota for complete local control and deep Home Assistant integration. This offers a very flexible and often more affordable option for those comfortable with a bit of tinkering.
