First app. Question!

dennis91

Hi All,

I'm creating my first Homey app, and i'm now playing with the ManagerSettings, because i need to set some values that persist through reboots/restarts etc. So i did that with : 

Homey.ManagerSettings.set("apikey", "hoi123");

After that i'm able to retrieve the setting again. But if i restart the app (without the .set method again), the value is empty again... how can i make it persistent ?

Regards,
Dennis

I think the settings are only permanently saved when the onSettings() function is called, this does not happen automagically when changing settings programmatically (see note at the bottom). Refer to
https://apps.developer.athom.com/tutorial-Drivers-Settings.html :

onSettings( oldSettingsObj, newSettingsObj, changedKeysArr, callback ) {
    // run when the user has changed the device's settings in Homey.
    // changedKeysArr contains an array of keys that have been changed

    // always fire the callback, or the settings won't change!
    // if the settings must not be saved for whatever reason:
    // callback( "Your error message", null );
    // else
    callback( null, true );
}

When changing device settings programmatically using setSettings(), the onSettings() function is not fired.
