Hi,
yes, I have found a solution. The developer helped me out.
It is very simple. Just keep the “” away from the page number. (Somehow it is %22 in my post above.)
Just open a browser and enter
http://ip:8080/remote?action=NOTIFICATION& notification=PAGE_CHANGED&payload=1
Please remove the space between NOTIFICATION& and notification. The text is written wrong if I put it together.
0 is page one. 1 page two and so on.
As an alternative you can try
http://ip:8080/remote?action=NOTIFICATION& notification=PAGE_DECREMENT
or PAGE_INCREMENT
I use these commands to control the mirror using my smart home gesture control.
Thats why I had no need to modify the remote control module.
Hope it helps you anyway.
In my case, it works like a charm.
