Hey @Joachim - we just missed each other! - I started a new thread to discuss your concern here.
Also - I was going to test out the ToF sensors you were using and the TSOP to see how sensitive it would really be but realized that it would be difficult to verify that a team hasn’t modified a part designed to emit IR to serve as detection blocker! I’m not suggesting at all that this was your intent but we should keep in mind to avoid rule changes that could be exploited like this.
