Nothing official at present.
There are two options.
If you just want to schedule your lightwave RF devices turning on based on rules in SmartThings, you can use the free IFTTT service/channel. The problem with this at present is that it’s only a one-way channel. You can tell the socket to turn on or off, but light wave RF does not tell smartthings if the socket was turned on at the wall. So it will work for some use cases but not others. The advantage of this method is it’s really easy and doesn’t require buying any additional devices.
If you have a strong technical background, some community members have created a “man in the middle” integration using a raspberry pi. This will work, but it’s quite a bit of effort to set up and maintain. You can ask any follow-on questions in that thread and the people who are using it should be able to help you.
