Sylvania lightify Smart Sensor 74388, Contact & Temperature


(Gus) #1

Hello all, so far i have been able to get everything i have purchased to work in ST, either from tips in here or because they just simply work!

Just got stumped on this one. I bought the Lightify RGB Lightify LED strips and they worked fantastic, with zero issues, so I figured this Lightify Contact switch would work as well, was I wrong!

If anyone has used this switch or can help me make it work, i would greatly appreciate it.

I have tried every Sensor and Thermostat available to me in the IDE when i edit the device and none work.

Many thanks in advance.

I believe you’ll need a LIGHTIFY Gateway (bridge) for this to work. You’ll want to purchase devices that work with Smartthing natively or with a custom DH (Device Handler). Most of these devices on this page will show what will work without having to add a Gateway (bridge), you have to read the devices you purchase to see if a bridge is needed or if it will work with just the Smartthing hub. https://shop.smartthings.com/products/samsung-smartthings-multipurpose-sensor I hope that helps you

I know its been a year, but adding this for sake of anyone else who may buy this item(Sylvania Lightify Contact and Temperature sensor, model 74388):

It does seems to work fine if you just set the device type in IDE to the built-in “SmartSense Open/Closed Sensor” I suspect that it has same “CentraLite” guts as the SmartThings device, as it seems to even recognize the firmware version as correct and all functionality - battery levels, temperature and contact sensor all work.

For what its worth, it took me setting the device type in IDE and then resetting the sensor by removing and replacing the battery before it started working. Not sure if this is required or just a fluke.

(To be clear, it works WITHOUT the Gateway Bridge)
