We have a Thermomix TM31 which I repaired a few weeks ago. On the control board I found an IR module and a LED beside that which both are visible from outside (left side of the display), but are not labled. Until now I couldn't find any documentation or information about this IR interface. It would be nice if someone will reverse engineer this. And maybe also an integration into the BSH-App. Then you could remotely start the cooking process when leaving the office... :-)
