Outdoor open close sensor

Yep. :sunglasses: We have had some community members in the past who lived in Minnesota who did this for gate sensors. But it does require running a wire to the location.

This is a common dumb sensor for this purpose because it’s highly weatherproof and very durable, and also handles somewhat larger gaps than the usual indoor sensors. But there are many of these from many different brands. Read the product descriptions carefully as many are designed for low power and you might need a transformer.

And here’s the community FAQ with a list of devices that have dry contacts, so you wire one of those those to the dumb sensor in order to integrate with smartthings. (The topic title is a clickable link)
