If you want to add the Tapt switches, you need to use a custom device handler, instructions posted in the following thread:
At some point, the Tapt switches could be recognized by ST as a Zigbee switch, but after an update from Wink this could no longer be used to pair them. Keep in mind that the device type required will not update the status of the switch in the app if you press the switch buttons.
As my two cents, if you are to use the ST hub, get rid of these switches. They are quirky (pun intended) and will go offline randomly. I am down to the last one of these and will be replacing it shortly. Just my two cents.
That one says the custum device type is no longer needed. I have added the device type in ide anyway but where should it show up in smartthings app? The problem is that when i search for the device, the st hub cannot locate it.
This custom device type is no longer needed. Your best method is to remove the device from ST, remove the published Device Type and add to ST. It will add as a ZigBee Switch which does on/off and instant reporting.
That was back when ST and the Tapt did play nice together. For some reason after a Wink update it stopped working like that.
After you add the device in the IDE, you need to go to the “Add a thing” button in the ST app and follow the instructions to add the switch by using both the top and bottom button.
Did you power reset the switch? Tapts are known for getting stuck into an unprairable state until you flip the breaker for the circuit.
Do you have a Wink hub you can try if it is working? Maybe it is a bad switch?
How far away are the switches from the hub? Might want to try and get them closer.
Also, if you have a long ethernet cable, just to try, get the hub farther away from the router. WiFi might interfere with Zigbee.
