Is there any way to have a stand alone Raspberry Pi with FPP setup so that I can manually 'play' a sequence or show with a button or some other way? I plan to not have it on a network or WiFi, or attached to a computer. I'd like to have it on my network to upload the show and do the config, then have it completely stand alone such as in a vehicle, and be able to play a sequence with the push of a hardware button. Also, keep in mind that it will not constantly be powered on, so relying on a clock or timer would not be an option. Any ideas? If not, any other hardware solutions for playing a sequence manually without a computer or net connection? I've seen the TS-1000 or T-1000S LED controller online, but it just seems so cheap and with no good documentation, and I'd have to rely on a different sequencing software - which I don't want to have to learn another one.
