I am using a Athom ESP32 controller with the shipped WLED-sound firmware on.
I am using the OpenHab binding
There does not seem to be a channel for power. I can add a switch to the “MasterControls” channel, which cosmetically will turn it off. However, this is not true on/off. The device has a power relay. If i connect directly to the controller via the wled web interface and press the power button there, I can hear the physical click of the relay power going on/off. The on/off from openhab is not activing the relay.
How do I access the true ‘on/off’ on the relay, via the openhab binding? the same “Power” that appears on the native wled UI.
You can get a 3.3 jar from here that should work on your core and will give you the new bridge/thing ability. This way you take care of a breaking change before making your upgrade to 4.x
