Unfortunately it’s stateless but you can integrate it into ST using IFTTT.
I have also integrated a Raspberry Pi into the mix.
So, ST turns on the Lightwave RF switch/outlet, this goes through the cloud to the Pi which used UDP to talk to the Lightwave RF hub via the local lan.
Works a treat and there isn’t much lag.
The light switches are dimmers and they have slave switches so that you can use for a hallway with 2 light switches.
I like the design too.
BTW I am in no way connected to LWRF I just like there product.
