Honours in Bachelor of Technology hold some value in the minds of the foreign universities and in the Honours you have to do some research and present your research in the form of a research paper. Since the good foreign universities are mainly research focussed, they take it as an opportunity and see that the student has a formal experience in research, which helps you score some additional points.

So in general yes, an Honours in your Bachelor of Technology has value in your foreign university applications. Hope I have answered your question. All the best!
