A warning about this controller!
It can apparently freak out for no reason and send garbage Zigbee commands that do weird things with your setup. I just spent a half-hour searching for the error I had made in my rules that was causing the siren on my Xiaomi Aqara hub to sound every time we pushed the button on this remote.
Spoiler! There wasn't an error on my part.
I couldn't find anything I had misconfigured, so I finally pulled the battery from the Symfonisk sound controller and tested it. It was still 100%. I put the battery back in and the weird behavior stopped. So if you're going to use this setup, I will tell you that it works, but if the sound controller stops responding to button 6 (meaning the volume would raise or lower uncontrollably), or things start triggering in your setup, seemingly by themselves, pop the battery for 30 seconds and see it that resolves the problem.
