 - Simple switch - a switch only, can be a fallback for many other unsupported devices, to allow just power to be switched on/off.
 - Simple switch with timer - a single switch and timer, will probably work for a lot of smart switches that are not covered by the more advanced configs above.
 - Simple switch with timer v2 - the above with timer moved from dp 11 to 9, confirmed with a Nexxt 220V smart switch.
