App for the old SG LEDDim dimmers (the ones that show up as @NDxxxx in Bluetooth). Homey talks to them directly, so you don’t need the SG gateway.

> Gateway-free Bluetooth dimming for the lights that were smart before the hub arrived.

Doesn’t work with SG Smart 3.0, that’s a different protocol.

Add the dimmers one by one, or use a group device to control a whole group from the SG app. If nothing happens, try network passphrase 1234 in the device settings. That’s what most installations use.

Unofficial, not affiliated with SG. Built on protocol work by nkaminski, fromm1990 and einaros.
