Hello team I try to add sonoff 2 gang, but just add it as one device, is there any option to add it as 2 or 3 gang
There are two different Homey apps in the App Store that support Sonoff Zigbee devices: Sonoff and SONOFF Zigbee.
Your ZBM5 switch isn’t listed in either app, which means that this switch isn’t currently supported. That’s why your switch was added as a “Generic Zigbee device,” which explains why the second channel is missing.
This means that you have to address your request directly to the app developers, on GitHub, or, if available, in the corresponding app topic here in the forum. You can find the relevant links in the Homey App Store on the app pages.
