I had issues learning from Dyson AM03 fan to MX-890 so I learned it in Philips Pronto and copied the Hex codes. (Thanks to Daniel Tonks and Duct Tape. )

1) When i learned the "Oscillate" command multiple times I noticed that the code is different everytime. I learned the code 5 times and it is different hex code all the times.

Is this a common behavior for all IR codes, or it has something to do with Dyson remote?

2)Reason for posting
There is only one switch for oscillate on/off in Dyson remote. I had to pick 2 Hex codes out of 5 and one works for ON only and one works for OFF only. Solved this issue by using a toggle command in MX-890 but wanted to know if anyone can give information on why the learned codes behave strangely.
