Heya Ron . . .
Using the custom device type you should be able to add your own icon or even better use the icon hack:
Its nearly 1am here but i knocked together some options for you, abstract but its a very obscure use case i guess … IR LEARNING DEVICES dont really have an icon standard as such hahaha
1.) IR & A SHEET // as if to represent rules for IR on a sheet of paper
2.) IR EAR // as if to represent listening for IR rules
3.) WAVE INTO IR // as if to represent signal going into an IR Device not out of…
4.) IR & CHECKLIST // as if to represent rules for IR on a sheet of paper
5.) IR & A COGS // as if to represent rules or settings based around IR
6.) IR & PEN ON PAPER // as if to represent rules been written for IR on a sheet of paper
7.) IR WAVE & A SHEET // as if to represent rules for IR on a sheet of paper
they are all icons with the correct BLACK 30% Opacity rule of thumb, so if used they will look like the rest of your icons style wise in the phone app . . .
hope this can help
cheers
