As my festoon lights are smart, but on FLUX platform, I might be able to leave that circuit powered on and then connect the relay button to something in LIFX for node-red to monitor and control soft power state on FLUX platform. Wondering now about taking it a step further. Thanks for the inspo…this was the final thing in my setup I couldn’t control with GA! Works great thus far and I’ve then got a Light entity using the switch platform in HASS which I surface to Google Assistant and my dashboard so I’m controlling a Light entity which subsequently uses the switch entity.

When you change the switch state within HASS this triggers a LIFX set-state to change power of the physical relay.

This will update the state in HASS, but the node will not output and fire a state change on physical switch

I query the state of the physical relay every second in case someone changes the power state physically on the switch, and if there is a change I pass this as a msg.enable true/false boolean to the HA switch entity.

Rather than a separate switch & sensor entity in HASS, I’ve got one switch entity I create in node-red.

In my setup I’ve got 80+ LIFX lights, but I only have 1 “dumb” set of smart festoons wired into a switch that I want to control, so I only care about controlling 1 relay of 1 switch (I have 13 ) Thanks for the inspiration ! FYI - This is how I’ve solved it similarly in HA with node-red.
