Pairing Lightwave MODEL L21

The gen 2 switches (Now call Smart dimmers) are not supported as Lightwaverf have not published any details on the new control method. The old range could connect directly but the new ones are on a different frequency and use a different protocol. Hopefully in the future lightwaverf will publish a public API to connect via the internet but until then all the automation controllers are in the same situation.
The only options are via IFTTT or possibly Homekit but neither are very robust.
