Yup! works fine with other devices - thanks.
The logic why you hve to learn an ID is beyond me though and toggle codes are a major nuisance with this ID system as it doesn't allow for 'dirty' codes (simulating both toggle states with one 'dirty' IR code - a frequently used trick in the pronto community).
I wanted to use a 3-in-1 remote for the misses as it is simple, well known and the 3rd device was free. Unfortunately it uses toggle codes, so no deal.
Ah well - back to the drawing table
