Frequently Asked Questions

How do I use it for a gate/garage door?
Connect the MINI-D’s NO and COM terminals to your gate motor’s trigger/wall-switch terminals. Power the MINI-D from the gate motor’s 12V battery (DC+ and DC-). In the eWeLink app, enable Inching Mode with a short pulse (e.g., 0.5 seconds). Now tapping the app button or saying “Hey Siri, open the gate” sends a pulse just like pressing the physical remote button.
Can I power it from my gate motor battery?
Yes. The MINI-D accepts DC 1248V. Most SA gate motors have a 12V or 24V backup battery, which is within range. Connect DC+ and DC- to the battery terminals.
What is a dry contact?
A dry contact is a relay that switches without supplying power to the load. The MINI-D’s relay simply opens or closes a circuit the load gets its power from a separate source. This makes it safe and versatile for gate motors, boilers, access panels, and other signal-based devices.
Does it work with Home Assistant?
Yes via Matter (recommended for local control), eWeLink HACS integration, or SonoffLAN. Matter provides the most seamless integration with full local control.
Can I connect AC and DC at the same time?
No. You must choose either AC or DC input never both simultaneously. The device has separate terminals for each.
What’s the difference vs the SV Inching switch?
The MINI-D is newer, supports Matter, accepts AC or DC (1248V), and has a proper NO/NC/COM dry contact. The SV Inching is older, WiFi-only (eWeLink), and accepts DC 524V. If you want Matter/Apple Home support or AC power, choose the MINI-D.
