This Tasker plugin allows you to send a (series of) ADB Shell command(s) to a remote device (or the device itself) that has ADB over WiFi enabled. This app obviously does need Tasker to work as it's a plugin (https://play.google.com/store/apps/details?id=net.dinglisch.android.taskerm, this is a paid app with a 7 days free trial). Again, without Tasker it WON'T WORK. Was I clear enough? Anyways... On the target device you can do anything you would normally be able to do when using the terminal
