You might look for shelly 1 gen4 alternatives if you need a different form factor or specific connectivity. The Shelly 1 Gen4 smart relay switch offers Matter support, Wi-Fi, and Zigbee without a hub. It fits in tight spaces with its compact 0.63-inch length. It also handles up to 16A loads and includes dry contacts for garage doors. These specs make it versatile for appliance automation and retrofitting into standard wall boxes.
However, you may prefer a standard wall switch, a dimmer, or a plug-in solution. Some users need Apple HomeKit compatibility or outdoor ratings. The alternatives on this list were chosen because their specifications overlap with the original. They share key features like Matter protocol support and hub-free operation. This guide compares 6 options ranked by their published data. You will find devices that match the Shelly 1 Gen4’s core functions while offering different physical sizes or circuit types.
How each alternative compares
Tapo Matter 3-Way Dimmer Switch Kit
The Tapo S515D Kit offers a complete 3-way dimming solution, whereas the Shelly 1 Gen4 is a single relay switch. Tapo provides physical dimming control for lights, while the Shelly focuses on on/off switching for appliances. The Tapo unit is significantly larger at 5.06 inches in length, making it suitable for standard wall boxes rather than the Shelly’s compact 0.63-inch form factor. Both support Matter and require no hub. Choose Tapo if you need multi-location light control. Choose Shelly if you need to fit a relay into tight spaces or control non-lighting devices like garage doors.
Leviton Decora Smart Wi-Fi Switch
The Leviton Decora Smart Wi-Fi Switch is a full-size wall switch, contrasting with the Shelly 1 Gen4’s compact relay design. Leviton requires a neutral wire for installation, while the Shelly fits into existing switch boxes without that requirement. Both support Matter and handle high loads without a hub. The Leviton unit is much larger at 3.88 inches in height. It is ideal for standard wall installations where you want a traditional look. The Shelly is better for retrofitting into existing setups or controlling appliances behind walls. Pick Leviton for standard lighting upgrades. Pick Shelly for flexible, hidden installations.
Eve Light Switch with Thread and Matter
The Eve Light Switch uses Thread connectivity alongside Matter, offering local processing for faster response times. The Shelly 1 Gen4 relies on Wi-Fi and Zigbee for connectivity. Both are on/off switches without dimming capabilities. The Eve unit is larger at 4.72 inches in height, designed for standard wall plates. The Shelly’s compact 0.63-inch length allows it to fit into tight electrical boxes. Choose Eve if you have a Thread border router and prioritize local control. Choose Shelly if you need a smaller device for appliance automation or retrofitting into existing switches without a neutral wire requirement.
Meross Matter Smart Plug with Energy Monitoring
The Meross Matter Smart Plug is an outlet device, not a wired switch like the Shelly 1 Gen4. It provides energy monitoring, which the Shelly relay does not offer. The Meross plug is larger at 2.68 inches in height and plugs directly into a wall outlet. The Shelly installs inside electrical boxes. Both support Matter and require no hub. Choose Meross if you need to track energy usage for specific appliances. Choose Shelly if you want to control devices permanently installed in walls or need to automate garage doors. The Meross is portable. The Shelly is fixed.
Kasa Smart Plug Mini with Energy Monitoring
The Kasa Smart Plug Mini supports Apple HomeKit, a platform the Shelly 1 Gen4 does not explicitly list in its compatibility. Both devices provide on/off control and energy monitoring. The Kasa plug is a standard outlet device, while the Shelly is a wired relay. The Kasa unit is larger at 2.62 inches in length. It is ideal for users deep in the Apple ecosystem who need energy tracking. The Shelly is better for hardwired installations or controlling non-lighting devices. Choose Kasa for Apple HomeKit integration and energy data. Choose Shelly for flexible, low-profile installations without outlet constraints.
