I’ve water proof my sensors with this …
Scotch Brand 860 Adhesive Putty Removable, 2 oz, Multicolor Amazon.com
I left the sealed sensor in a cup of water for a week with no issues.
It leaves no residue and it’s reusable too.
Just roll it between wax paper with a seam roller or a bottle.
Peel and apply …its tacky enough to use as a replacement for the factory mounting tape.
My metal mailbox sensor … When opened Wyse cam takes a video and Alexa says, “You’ve got mail”.
