@luisestrada Yes, however, It can only be “one” control sensor / HA-module. So, if you have a bunch of lights, and you want to have only one “show” only when that specific light is “on”. You will have to add the module one time / light…
But if you have a specific light that you want to use as a “control sensor” for all the lights, only one module is needed…
I think you could also use an “icon” and some trickery to only show an Icon when the light is lit and when it’s not, not show anything… But not sure… :)
