I’m happy to announce that with version 2.16.0 of the Android app it’s now possible to configure multiple servers. Please have a look at the docs for a list of supported features in the multi-server mode: Android App | openHAB
The new version can also display the new main UI of openHAB 3.
I started the rollout in the Play Store at 20%, so not everyone will receive it now. If you don’t want to wait, you can get it from the GitHub releases page: Releases · openhab/openhab-android · GitHub
Please leave your feedback in the topic Android App Beta.
