The instructions are straightforward from SkyBell, however in short you just kill the breaker, hook the two wires to the base plate genius improvement as previously you had to wire to the device and then mount it to the mount and it was a pain, now the device isn’t involved until the very end at all and then mount your mount to the wall. I have used a combination of screws and glue for these installs. SkyBell provides a nice drill bit in the box if you would like to drill two holes into the house. For my stucco installation I did use two holes, however I chose to use my own masonry bit on my stucco just to be safe. The install was straightforward and completed in under 5 minutes. For the 2nd installation I did I was on some decorative uneven stone and this was quite the challenge as it would be for any doorbell installation.
