New to the smartthings system. Have a starter kit and a few add ons. Have an idea for my next use but have a feeling it may not work so looking for experiences.
Our postbox is on the side of the house where it can’t be seen from inside and so you never know when the post has been delivered. I was thinking of putting a smartthings door contact on it so I know when post is delivered but it’s an all metal post box which I have a feeling may have an issue with signal? Any experiences??
