Running on Android

Using theTermux app makes it easy to runNode-RED on Android devices. Get it directly from theirgithub or viaF-Droid hereTermux on F-Droid.

Note that the Play Store version is not maintained.

Note : the Node-RED team have no connectionwith the Termux application nor its development, nor F-Droid. We cannot provide support forit in any way, other than to say that at this point in time it works.

Installing

Install it, and run it. Then at the prompt type

apt updateapt upgradeapt install coreutils nano nodejsnpm i -g --unsafe-perm node-rednode-red

Then you can point a browser tohttp://localhost:1880

Note that installing openssh may make interacting with termux a little easier.see this thread for a description of one such install.

Notes

You can also npm install other node-red nodes such asnode-red-dashboard in the standard way :
```
cd ~/.node-rednpm i node-red-dashboard
```
or via the Pallete Manager.
Thevolume-down key is the ctrl key - sovol-down-c can be used to “break” a running app.
The instructions above also install thenano editor, which is useful for editing files.

Autostarting

The recommended way of starting applications running in Termux is using theTermux:Boot application (available fromF-droid - note that the Play Store version may not be maintained, and it’s recommended to use the same source that you installed termux from).

We have found this other app useful for autostarting Termux on boot -Autostart - No Root (Note: with termux:boot, use of other autoboot apps does not seem to be required).

Note that the shebang in the node-red script is incompatible with termux:boot scripts. The workaround is to start node-red using a termux:boot startup script like:

#!/data/data/com.termux/files/usr/bin/shtermux-wake-locknode /data/data/com.termux/files/usr/bin/node-red

Device Access

You can get direct access to various hardware on the device by using the extraTermux device plugins - which can then be accessed viaNode-RED using theexecnode.

Note: you need to install both the add-on app, and also the add-on api in Termux.

Install add-on app - Termux:API from the same source you got termux.

Install add-on access into Termux

apt install termux-api
