Thanks for making this video! It was exactly what i was looking for. I was able to put my sensor into the wall (we have sheetrock) and everything is completely hidden.

I love this simple idea. This could be really handy for any kind of door. The only issue I see is that it does not look good as is. There would be the need to hide it better. I will make up my mind about this and might post a video myself in case I came to a conclusion

Sweet. Is this a sliding glass door you are attaching to?

If you do not remove the reed contact on the lock sensor it can bee trick with a big magnet
