I think everyone is saying that if you tried to wire a Z-wave open/close sensor into an existing wired door/window sensor that is connected to an alarm panel, you will fry the battery operated z-wave sensor. (Whew, sorry for the long sentence)
Is this correct?
Can I disconnect the wired sensors from the alarm panel and then wire them directly into a z-wave open/close sensor (ecolink)?
Too expensive to put a sensor on each window, too many.
I know this post is 2.5 years old now, this is exactly what I’m planning to do but am new to optocouplers/isolators, can you share more info on what exactly you used and where you got them from?
I’m pretty surprised no one has released a wired Z Wave motion sensor.
I’m not looking to replace the entire security system, but it would be nice to replace my wired motion sensors with wired Z Wave-enabled motion sensors.
That way it would not impact my current alarm system setup – it would still receive the motion signal – but the Z Wave integration would allow for communication back to ST.
It seems like a pretty simple thing to have an out-of-the-box solution.
That is for power only, though. The sensor would need to still be able to send a single back to my security system, while also communicating with ST over Z Wave.
Sorry totally my fault for not reading your post carefully. What you can do is use a GoControl contact sensor and tie it to your motion sensor at the alarm panel. That way you don’t have to replace the motion sensor. This post has the DTH for the sensor. This is all depend on what type of output your motion sensor is providing.
This isn’t quite the answer the the OP’s question exactly. However, it does allow you to utilize your hardwired sensors with SmartThings. It was a kickstarter project and it is now available for purchase: https://konnected.io There is some wiring and setup but the videos are really helpful and hold your hand through the whole process. It is close to a plug and play solution.
