Compatibility snapshot

Why it stands out

• three independent dry contact relays in one compact module, making it extremely versatile
• can control garage doors, fireplaces, sprinklers, or any low-voltage device
• each relay is independently addressable in Home Assistant via Z-Wave JS

Reasons to hesitate

• wiring three relays takes patience and is not a beginner project
• no built-in enclosure for wall mounting, you need to plan where to put it
• needs an external power supply (USB-C or 12-24V), so you must plan power as well as wiring

Best for

• DIY home automation projects needing multiple independent relay controls
• garage door openers, motorized shades, or fireplace switches controlled via Z-Wave

Avoid if

• you want a simple plug-and-play device, since this requires wiring knowledge
• you have a low-voltage-only application and cannot supply the required 12-24V or USB-C power

Buying reality check

Price notes: Great value when you consider you get three relays for the price. Cheaper than buying three separate relay modules.
