The Sonoff Mini-D relay is just the device I was needing. I've had Zigbee/Wi-Fi challenges with a relay I use for my gate opener. I was able to set it up via Google home, and it paired to HE just fine, but as a generic device.
I set it to generic switch, and, replaced it in several apps, and so far so good. A native driver may simplify some apps (need a momentary closure of the contact for example) but workarounds have sufficed for me thusfar.
