Issue of the topic:I set up the openhab service and added bindings for a smart plugs and a bulb, added the models.
All connections to the server are local ones i.e. the devices are all in he same network.
From my PCs (Firefox) I can control the devices, but the Android app fails to connect telling me:" Authentication failed please check the configured username and password respectively the provided SSL client certificate (HTTP code 401).
I use the same username and password as with the PC browser.
I get the same message whether I use https://[ip address]:8443 or http://[ip address]:8080.
Using https://[hostname]:8443 I get “Connection to local server failed and you haven’t configured a remote server.” https://[ip address]:8443, http://[ip address]:8080 or https://[hostname]:8443 gives me a blank browser window but no error message. Correction http://[ip address]:8080 and http://[hostname]:8080 work. So it is probably an issue with the SSL Certificate I did not replace yet.
Please give me advice on how to use the app,or at least the browser on the phone.
Not sure why you think that. The Android app works fine with openHAB 3, and is still in active development.
When you install the app, it should automatically detect your server at setup. Did this happen? Ideally, it should be “http://ip-address:8080”, and you don’t need login information (though you can add it later).
My suspicion is that the app is looking for a sitemap, and you haven’t created one. When you use this IP address and get a blank page, are you able to swipe right from the left side of the screen to open the app menu? If so, click “openHAB 3 UI” to see the Main UI.
If this works, go into the app settings and and change “Start page” to “openHAB 3 UI”.
You don’t have to create a sitemap, but for a long time they were the default way to control OH. It might be that the app needs to be updated to point to MainUI as the default.
