I have 4 sets of LED security lights on the house. They each have there own switch. I would like to group them together to be able to operate from one switch and Alexa. I would also like to tie in to my alarm system. I have a dry contact on the panel. The switches do not have travelers only single pole switches.
The easiest solution would be to replace each switch with a simple ON-OFF smart switch. Then group them together in Hubitat.
