Smart Home Automation Hub Review – Samsung SmartThings Hub 3rd Generation

I already have a SmartThings hub with several devices and am expanding my device types with my first water leak detection sensors (new generation). This sensor was easy to connect to the SmartThings hub (30 seconds) and test out. I like that it has sensors on both the top and bottom of the unit.


I configured the SmartThings hub to send a push notification to my phone if a leak is detected. When testing the sensor, I was pleasantly surprised by two things. First, it is extremely sensitive. All I had to do was lick a finger and put it across the probes and they set off with that small amount of moisture. Second, when I tested it, I received the push notification on my phone in about two seconds. Both of these characteristics are exactly what I want in a leak detector.


The battery life appears to be pretty good. In two weeks, the battery has only dropped 2%. At that rate, the battery should last just under two years.


  • Connectivity: Wirelessly connect and control a wide range of compatible smart devices from 40+ partner brands, including voice assistants, lights & switches, speakers, cameras, sensors and more
  • Home Automation: Teach the hub your Good Morning, Goodbye, Goodnight, and other routines to automatically turn devices on or off throughout the day
  • 24/7 Monitoring: Receive app alerts from connected devices when there’s unexpected activity in your home.Material: Plastic
  • Voice Controls: Use voice commands to control connected devices using SmartThings and the Google Assistant
  • Improved DIY Solution: Improved guided onboarding for easier setup. Hub connects with Wi-Fi so does not need to be connected to an Ethernet cable
  • Compatible with previous versions of SmartThings Sensors and Outlets
  • Download new SmartThings (Samsung Connect) app for initial set-up. (Tip: You can still use SmartThings Classic app once initial set up is completed)


You don’t need automation for these, as you can assign actions to the device directly. BUT, you may find this useful if you want the most flexibility. I wanted single press to turn a light on or off- a toggle. This particular lamp is plugged into a smart switch / zigbee repeater. To do this, I created a custom automation (in the new app, apparently I like pain). To turn on, the action was set to single press AND the condition was added that the smart switch is consumed 3W power or less. If both are met, the light turns on with a single press. For the off automation, everything is the same except the power is 3W or greater and the light turns off. Now the button acts as a true single press toggle. And I still have double-press and hold available to assign.


  • Support floor leak sensor (same as 1st generation) and drip from above (new to 2nd generation)
  • Include temperature sensor (same as 1st generation)
  • Cheaper than 1st generation
  • Excellent battery life


To make things better, get yourself a ZigBee plug-in device (or two) and place it (them) strategically between the hub and the device you are having problems with. The key is to have enough devices to build a strong mesh.
