Oh Ok. So essentially I want to create a Hub that does 2 things check/display the state of my chicken coop's door via nrf and a security system that is protected by a password. I’m currently debating whether I should attach a pir sensor to the hub or use the nrf module to have a second transmitter trigger the alarm from somewhere else in the house to trigger the actual alarm. It all depends on if I can get this nrf stuff to work well in my combo code, since it did work just fine outside of the combo. Both sketches work fine by themselves, so I don’t understand why it just freezes up when I try to combine them. I mean the password code isn’t that taxing right? Should I maybe post this as another forum topic?
