Once all the above is done we can start our node-red service! Lets get the device IP so we know where to connect to. If this doesn't work then you have likely missed something above!

Now that we have the above setup we can run something like termux-camera-photo ~/storage/dcim/1.jpg and this should store a photo in our DCIM folder (The usual place camera photos are stored) and we can find it using a folder app. Then to allow access to our camera, in the Termux app input termux-camera-photo 1.jpg this should prompt android to request access to the photo. To allow access to our storage we do this by running termux-setup-storage in the Termux app, this creates a syslink in Termux to our android storage. Which means we need to give Termux permission to access both our camera and our storage. We are now about ready to go! Because of androids permissions we need to make sure we have allowed Termux access to the sensors we want to work with.įor example, if we want to take a picture with node-red we need to remember we are running on Termux.

Ok, so now we have Termux setup, including the device access part (This part is important, we do't get access to our sensors without these steps). Some additional Termux setup which can be found below.

Termux installed on the device - Use the great node-red guide here follow all of this guide including the Device Access part!.An android phone or tablet (Sorry Apple fans).

Using Termux means we get access to the devices sensors as well as any node-red modules we want to install! It's a little bit of a fiddle to get up and running, but shouldn't take too long! There is a few ways to get node-red running on android but my favourite is with Termux. If you are like me and have the odd mobile phone laying around from previous contracts or even the dreaded 'I dropped my new phone, so I have to use my old backup' phone, then maybe this is a project you would be interested in!
