Since you said you tried GE switches, I’m assuming you’re in the US. So there are a couple of options depending on the specific use cases you have.
One) use smart bulbs. This is probably the easiest. There are many control options. See the following topic:
- use Lutron Caseta switches and the IFTTT indirect integration. These switches do not require a neutral and work fine with LEDs.
The problem is that there can be lag. Everything generally works fine for scheduled events (assuming, of course, that the SmartThings scheduler is working). Or if you are using your phone as a presence indicator and you just want the lights to come on before you get home.
The wall switch also works fine manually, although you won’t get status updates in ST. That’s OK For some use cases, not for others.
Where it tends to fall down altogether is if you want to turn on lights with a motion sensor. Then the lag may just be too long for many people.
There will probably be more options in this device category in the future, so you could also just wait and see what’s available in a few months.
