Hello, I moved your post to https://rivalrebels.com/en/boards/forum/2/q-a
as Game Community is not the correct place for this type of topic.
To answer your question, you can't remote detonate. The Detonator is for Plastic Explosives, not Nukes. If you want to activate a nuke from far away, you would either have to extend the timer using chat commands, or with redstone, a lever, and a hopper.

well, I'm a modder so if you wanna modify the detonator to detonate any nuke and explosive, you modify the code in the rr mod.
