What exactly are you looking for in a door sensor. Is it a contact sensor that will just tell you if the door is open or closed? Or is it a tilt sensor that will tell you when a door is moving? The reason I ask is that there are a couple of different options, but it depends on the specific use case. Quite a few people in Canada or Minnesota have used a nonnetworked gate sensor for open/close and then run its contacts to a smart things – compatible sensor inside the house. It’s similar to what people do with doorbells. That can work quite well and we’ve discussed some of the options previously. Here’s a typical gate sensor: [http://www.smarthome.com/seco-larm-sm-226l-3-magnetic-garage-door-contact-switch.html](http://www.smarthome.com/seco-larm-sm-226l-3-magnetic-garage-door-contact-switch.html) And then you would connect it to a networked sensor in the same way that people do for a pressure Mat: > [@United security pressure mat](https://community.smartthings.com/t/united-security-pressure-mat/12101): > > Hi folks - has anyone tried to connect and make work the United Securities z-wave pressure mat? I would like to use this to send me a txt when someone is standing at my front door and to turn on the light when we walk downstairs. Our stairs are in the middle of our house so a motion sensor won’t work without creating a bunch of false alarms. Ken If you’re looking for a tilt sensor, the Kumo wireless tags are an option. They can be used even inside the freezer and have an operating range going down to -40 Fahrenheit. There’s a community – created device type handler for them. Each tag cost about $40 and you also have to buy their ethernet bridge for $60 (one Bridge for up to 40 tags). > **[Wireless Tag - Specifications](http://wirelesstag.net/specs.html)** > > Wireless sensors for locating items, logging and monitoring presence, temperature, humidity and motion events from anywhere with Internet access, on iPhone/iPads, Android devices and laptops.

There is a service manager SmartApp that allows you to log into your Wireless Sensor Tags account and reads what tags you have registered. You can then choose which tags to connect to SmartThings. The main support so far is for the Wireless Motion Sensor Tags (temperature, humidity, motion, and open/close plus more). The moisture / water sensor should also work, but I didn’t have one to test. The other types of tags should mostly work as well, since their system reports data consistently from the different tag types. You can get the code here: I’ve tested it quite a bit locally, but there may be a few bugs left to iron out. I need a couple beta testers to verify. smile Here is the link to the tags themselv… --- _[View the full topic](https://community.smartthings.com/t/ac-powered-door-sensor-for-cold-weather/61685)._
