Hey there, I want to control my smartphone camera and taking pictures via node red. But I have no idea how to fix this that Node red communicates with my smartphone camera.

If your input is an image it is a binary file you need the output format to be "a single buffer object"

What command do you think the exec node is running? Put a debug node on the output of the function node and see what it shows.

thougt this is the command for the exec: "termux-camera-photo test.jpg"

If you run that in a terminal on the phone does it work?

Well that is the problem then. Nothing to do with node-red. How do you know it is not working?

I ve allready installed it.. It just shows noting and expect the next command

What do you expect to see in the terminal when you enter the command?

that a picture named test.jpg is generated

I asked what you expect to see in the terminal. I don't see anything in the description of that command that says it will confirm that it has done it. The command has not shown an error so I would expect that it thinks it has done it.

Have you installed the Termux API addon? If not, start there. If yes, what do you see in the terminal when you type that command by hand?
