First, as far as whether they need repeaters or not, it just depends on how you have your network quote back bone“ laid out. Start by reading post 11 in the following thread, then go up to the top of that thread and read the whole thing, and then you should have a much better understanding of whether or not you will need to add devices to get a good signal.

Why don’t you take a look at the device class features FAQ, and it will give you an idea of what features to look for in motion sensors:

Then after you read those two FAQs, we can talk more if you still have any questions. :sunglasses:
