4CH Wi-Fi/RF Smart Dry Contact Relay – Control Multiple Gates and Systems Remotely

Product description

Do you have to manage multiple gates or access systems separately, one at a time?

What if you could control all four of them from one device and one app?

This 4-channel smart dry contact relay fixes that.

It connects to your existing gates, garage doors, and access systems and lets you trigger each one independently from your phone, voice, or RF remote. One device gives you centralized control over up to four separate systems.

Simpler access, smarter control, all from one place.
