Paul,
On Supernova's website, there's a Contact Us email for support and tech questions. Pop them an email and ask if the standlight feature will work if it's wired to the Cyo. I asked them a few questions about the E3 before I bought mine, and they were quick (under 3 days) to get back with me about tech concerns.
