I do have an idea to keep it hardwired, but will see how it works out, it was already hardwired about 10ft, but needs to be another 5ft now.
I remember years ago when my mate was living with his parents, and he wanted to hardwire it to the box, in the living room directly below his room. We drilled a hole in the external wall, ran it outside and back into a newly drilled hole into the living room. F*ck knows what we were thinking but we were youngish. I told him to tape it to the other wires that were outside, but he couldn't be bothered and it was the most obvious thing ever, his mom came home and realised within about 30 seconds and went nuts.
