I have a non z-wave motion sensor which i would like to integrate into my Vera. The switched output is 240V. I was thinking of using a dry contact to give me a on/off status in Vera. Is that the way to go ? Any recommendations for a cheap solution ? I am in the UK so need UK/EU frequency. I dont think i could use the Fibaro universal sensor, as that can only handle 30V if i am right.
