Im using Broadlink now, Ive imported a load of light switches, I have transmitters and receivers and some nice looking wireless light switches, everything works from Alexa, and when I part set or full set the alarm it switches off all my lights in the house (I got fed up with coming down in the morning to find the kitchen light has been on all night) I also have courtesy lights, the hall light comes on whilst arming and goes off when set, it also comes on when you open the front door but you have to switch them off manually. Lights also come on when the alarm activates. The best bit about the light switches is they dont need a negative to work, so they are a straight swap for standard light switch. I have a couple of broadlink pros at home and one at work, I can control stuff at work like my aircon or lights from alexa at home or at work , and vica versa
