Others may want energy monitoring capabilities that this relay does not provide. The alternatives were chosen because their specs overlap with the original. They share connectivity standards like Zigbee or Wi-Fi. They also offer compatibility with major smart home platforms. This list compares 6 similar picks to help you find the right fit for your automation needs.
Our top pick: SONOFF Zigbee Dry Contact Relay.
How alternatives compare to SONOFF
Aqara Zigbee Wireless Mini Switch
The Aqara Zigbee Wireless Mini Switch differs from the SONOFF MINI-ZBD by offering manual control rather than automated relay switching. It is a small remote designed for users who already have an Aqara hub. While the SONOFF unit handles dry contact outputs for motors and garage doors, this Aqara device acts as a Zigbee button compatible with HomeKit, Alexa, and Google Home. You choose this if you need a compact remote input instead of a power switch. It lacks the voltage flexibility and high-power device support found in the SONOFF relay.
BroadLink RM4 Mini Universal IR Blaster
The BroadLink RM4 Mini focuses on infrared control rather than Zigbee relay switching. It connects via Wi-Fi and targets legacy appliances like TVs and air conditioners. Unlike the SONOFF MINI-ZBD, which uses a Zigbee gateway and handles low-power DC motors, this device sends IR signals to control existing electronics. You should pick this if your goal is voice control for older non-smart devices without adding new wiring or hubs. It gives up the mesh network extension and dry contact automation capabilities of the SONOFF unit.
BroadLink RM4 Pro IR and RF Smart Hub
The BroadLink RM4 Pro supports both IR and RF signals, whereas the SONOFF MINI-ZBD relies on Zigbee for relay control. This hub connects via Wi-Fi and is designed for legacy appliances using radio frequency or infrared. While the SONOFF unit automates garage doors and access systems through dry contacts, this BroadLink device bridges the gap for non-smart TVs and motorized shades. Choose this if you need to control RF-based devices that the SONOFF relay cannot handle. It lacks the Zigbee mesh extension and local control features of the SONOFF product.
The Frankever R4 is a Wi-Fi IR blaster for controlling legacy electronics, differing from the SONOFF MINI-ZBD’s Zigbee relay function. It connects directly to Wi-Fi and targets TVs and air conditioners via infrared signals. The SONOFF unit automates low-power devices like garage doors using dry contacts and requires a Zigbee hub. You should select the Frankever if you want simple voice control for older appliances without managing a separate smart home protocol. It does not offer the voltage flexibility or mesh network benefits of the SONOFF relay.
The Jinvocloud Zigbee Contact Sensor monitors door and window status rather than switching power like the SONOFF MINI-ZBD. It uses Zigbee connectivity to send alerts to Alexa or Google Home when a contact is broken. While the SONOFF unit acts as a relay for motors and garage doors, this sensor provides security and automation triggers based on physical opening. Pick this if you need status tracking for windows or doors instead of device control. It lacks the power output and wide voltage input capabilities of the SONOFF dry contact relay.
The Samsung SmartThings Hub 3rd Generation serves as a central bridge for mixed Zigbee and Z-Wave ecosystems, unlike the SONOFF MINI-ZBD which is a single relay device. It supports Alexa and Google Home integration while managing multiple protocols. The SONOFF unit automates low-power devices via dry contacts and extends Zigbee mesh coverage. Choose this hub if you need a unified system for diverse smart home devices rather than a specific automation switch. It does not provide the direct dry contact output or AC/DC voltage input of the SONOFF relay.
