Samsung - SmartThings Multipurpose Sensor - White

I have a few these already so I knew what to expect. It paired easily with the smartthings base according to the directions. I installed this one on my garage door. I had to make a bracket to mount the sensor but it works great. Tells me when the garage was opened, closed and gives me a temp reading in the garage. Works as advertised. After a couple months installed the battery is still in the 90%. I have had other smartthings sensors for about 6 months and have not had to replace a battery yet.

Purchased devices to monitor heat and water issues for a rental property in a distant location from home. So far, very satisfied!

SmartThings pushed out an update a while back and these sensors have been worthless ever since. They CONSTANTLY go offline and the only way to get them back online is to pull the battery out, reset it, relink it to the network and then delete the old one. Then do it again a few days later when they go offline again. I'm not exaggerating when I say that at least one goes offline every day or two. My attached screenshot shows $160 worth of sensors offline and worthless. The idea of using these as window/door sensors is for peace of mind and security. Since the update, they're more trouble than they're worth. Other SmartThings work reliably (light bulbs, motion sensors, etc), but these are useless. Don't buy them at any price.

The key word is "Multipurpose". There are so many options on what you can do with this thing! Very happy with purchase. As a suggestion, when setting these up, remove the plastic cover and pull the battery out and remove the plastic strip that separates the battery from the contact versus pulling on the plastic tab end. On each of mine this left a small piece of plastic that caused it to go offline randomly until I pulled the battery out and found the small piece of plastic.

The sensors work great to let me know when sneaky teenagers are trying to leave the house or have persons come over when I'm not home! Kids are using technology… You can use it too! Fight back parents!

We purchased the SmartThings Hub security system for our home. I installed everything myself and it was very easy. The only downside is that it's very sensitive and if the contact isn't flush/on the same level/ as the pairing piece then it registers as the contact being open even if the window or door is shut. I had to buy thicker Velcro pieces to make it level with each other, the ones provided didn't do the trick.

The multipurpose sensor has one particular use I am interested: if a door is open. I have this installed on my sliding glass door that goes to the back yard. If it is open, I have it set up so the A/C won't turn on. That you can set things up so you don't waste the A/C with windows/doors open is what makes a smart home smart! Additionally, this sensor has a thermometer so I can tell what the temperature is at the slider. Use this with SmartThings hub or some other smart home hub. My only gripe with it is that it keeps falling down. I've resorted to extra strong double sided sticky tape.

Installed these as extras with my smarthings hub, I added one out at my mailbox also so that I can tell when the mail man has come and get an alert also on my phone! As an added bonus since it has a built in thermostat, I can easily check to see how hot/cold it is outside.
