You can manage EtiSalat devices remotely through this app.
Please keep in mind, this is not the official EtiSalat app, but through this RC app, you can control it.

Our app has several remote models, so you can choose the one that works with your device.

The app was developed so that you could use your EtiSalat device even when you can't find your remote control! However, your phone must have an IR sensor on your phone.
