* Sonoff D1 dimmer 433
*
* 0 1 2 3 4 5 6 7 8 9 A B C D E F 10
* AA 55 - Header
* 01 04 - Version?
* 00 0A - Following data length (10 bytes)
* 01 - Power state (00 = off, 01 = on, FF = ignore)
* 64 - Dimmer percentage (01 to 64 = 1 to 100%)
* FF FF FF FF FF FF FF FF - Not used
* 6C - CRC over bytes 2 to F (Addition)
*
* Based on Gravitate1:
* When I switch the light ON via the app, I get:
* AA 55 01 04 00 0A 01 64 FF FF FF FF FF FF FF FF 6C
*
* When I switch it OFF, I get:
* AA 55 01 04 00 0A 00 64 FF FF FF FF FF FF FF FF 6B
*
* When I set it to 1%, I get:
* AA 55 01 04 00 0A FF 01 FF FF FF FF FF FF FF FF 07
* AB 55 FD F7 FF FF F5 01 FF FF FF FF FF FF FF FF 09
