Do they make an outdoor gate contact sensor that not $80? Thank you
I think it depends a lot on the details of your use case.
How far away is the gate? Is it metal or wood? Is there line of sight to the receiver device or trees/hills in the way? Stuff like that. Commercially available devices are presumably weatherproof and intended to work over longer distances than most z-wave/zigbee contact sensors that are typically used indoors, so it would make sense for them to cost more.
There are examples of how people have modified cheaper contact sensors for outdoor use, here and in the smartthings forum.
It’s actually my porch gate. Like 15 feet from my hub
Have you tried a regular contact sensor? Some silicone sealant could go a long way towards adequately weatherproofing it if it's not very far away.
