Normally I would google then trial and error these things myself but in the interest of time I’m gonna just ask here and hope you will help me figure it out. I need to put sensors on our backyard gates that will tell me when they aren’t latched.
A little background, our pool tech (very fired now) left our gate open when he left and this tragically led to the loss of our dog. I simply can’t allow this happen again. I’ve added auto-closing mechanisms but I’m paranoid now and believe in defense in depth strategies. I have two gates, one on each side of the house. I am thinking of using two mesh devices and a Xeon in the house itself. The Xeon will have a simple RGB light that gives a red/green status and will be by the back door. No green, no letting the dog out. A simple magnetic reed switch would tell me the gate is closed but not if it is latched. The current latch is like this:
What suggestions do you have in general for a sensor that would work and the “design” in general? We simply can’t lose another beloved pet so I want to make sure the gates are secured anytime we let a dog out to do their business. I’ll also have it send an alert for any gate open condition and a gate closed confirmation but being able to get a visual confirmation of the current state would make us all feel much better. Thanks in advance!
