Wondering if it's possible to use a tingbot app remotely?
I had thought about installing VNC and remoting in from my phone that way but I'm guessing that won't work as there will be no x session to latch on to?
You're right that most VNC servers latch onto the X session, so that's not going to work.
I haven't tried but this project might work: https://github.com/ponty/framebuffer-vncserver it's display only though, so you'd only be able to see what the app was doing with that.
Maybe you could use webhooks to send commands to your app?
