I used the JP1 version of IrTool with decodeIr.dll to decode that. It is NEC1 device 0.16, function 16.

You could use MakeHex and either Hex2CCF or IrPanels to make a CCF file of all 256 possible signals for NEC1 device 0.16. I don't expect there are discrete power signals, but it isn't that hard to test all 256 functions and see.
