With Pimote you can save a profile for each user of several Pis and for each profile you can save commands in buttons. By clicking the buttons you set the pins or your Raspberry to voltage or ground. Therefore your Android device needs to use the same network as the Raspberry Pi.
Note: The pin layout is set up for Raspberry Pi 2 and 3, other versions won't work. Raspbian recommended. The first click on a GPIO button sets the pin to voltage, the next click sets it to ground, and so on. Furthermore SSH on Raspberry Pi needs to be enabled.
To change command buttons just hold them until window appears that allows you to change your previous input. If you want to create a button that works like those from the scheme you only have to insert the number of the pin you want to set voltage on the first click and ground on the second.
No ads included. No data will be shared. Permission for Internal Storage needed to store profiles, nothing else.
