Getting Started

On first start the app tries to discover your openHAB server. This will only work on local networks and when the server does not enforce either authentication or HTTPS. If it fails, you can click on Go to settings and manually enter the server settings.

The URL field(s) might look like one of the following examples:

  • IP address:
  • Local hostname: http://openhabianpi:8080 (depending on your network the suffix .local needs to be added to the hostname)
  • Remote domain name: for an openHAB cloud account with myopenHAB

Local server settings: Please enter the base URL of your openHAB server, as you would enter it in the browser to reach the openHAB dashboard.

Remote server settings: If your openHAB instance is reachable via a public address/domain from outside your home network, these settings will be used when the local connection is not successful. Make sure to secure this connection against unauthorized access. There are a number of strategies available to provide secure remote access to your openHAB server.

Permanent Deployment

If you want to use openHAB Android on a wall mounted tablet, go to settings and select Disable display timer and Fullscreen.

Alarm Clock

The openHAB app will send the next wake-up time from your alarm clock app to the server. The time is sent as a number containing the number of milliseconds since the epoch. The Item name's default is AlarmClock, but you can change it in the settings.

Example item definition:

Number AlarmClock

Example rule:

rule "Alarm Trigger"
    Time cron "*/10 * * * * ?" // Every 10 seconds
    if (AlarmClock.state as Number == 0) {
        // Alarm is turned off
    val diff = AlarmClock.state as Number - now().millis
    if (diff <= 15000) {
        // Turn on stuff, e.g. radio or light
        logInfo('AlarmLogger', 'Turn on light')


Help and Technical Details

I don't receive any notifications

Please have a look at the "Push notification status" on the About screen in the app. If it claims that your device is successfully registered at FCM, please open an issue on openhab-android project on GitHub or create a thread in the forum.

My notifications are delayed

All notifications are sent as "high priority" messages, which means that the device and the openHAB app are waken up and display the notification. However vendors/third parties can implement custom "cleanup", "optimization" and "battery saver" apps, which might lead to delayed notifications. Please have a look at how to make an exception for openHAB in these apps.

My voice command rule isn't run

Please make sure Default Human Language Interpreter is set to Rule-based Interpreter (http://openhab:8080/paperui/index.html#/configuration/system) and Rule Voice Interpreter => Configure => Select correct item (http://openhab:8080/paperui/index.html#/configuration/services?tab=voice).
