I have six IKEA Symfonisk Zigbee sound remote controls available.
Five of the gen 2 version with five buttons in white, and one of the gen 1 version with the rotary control in black.
These are useful to someone using Home Assistant with Roon, because they pair easily with Home Assistant via the ZHA integration, and then they can be used to control a Roon zone via the Roon / HA integration.
You can read about the gen1 here: IKEA Symfonisk Sound remote
And these is a little discussion about the gen2 here: Roon module for Home Assistant - #367 by GregD . If you search you will find a few other people using these (the gen2 is better than the gen1 because of the extra buttons)
I used the gen2 versions throughout my house. As well as the usual play/pause, next/previous and volume up/down I had buttons set up to play my favourite radio station, group and ungroup and transfer between zones.
IKEA have stopped making these - so they are now getting hard to obtain (and expensive on ebay).
Why am I letting these go? We have wall mounted controls for our multi-room audio system and I’m switching to another Zigbee controller which I have found a way of mounting on the walls without driving my wife crazy (I mounted one of these on the wall and she hated how it looked - she wasn’t wrong).
I have all the metal cradles, and some of the sticky pads they came with (you can use mirror pads if you need new pads) as well two 3D printed wall switch mounts (which are a little ugly and do not have a recommendation from my wife).
When I unpaired these from HA most had 100% battery, the lowest was (I think) 86%.
I don’t expect I’m allowed to ship with the batteries, so can ship without - or if you can get to London we can meet for coffee and you can collect.
I suspect the US versions of these use a different radio frequency - so these are probably only useable in the UK (and maybe Europe)
I was introduced to these by the community here, and the controller I’m replacing them with uses code written by someone here - I’d like to return the favour so I don’t want payment but will trade for a CD or lossless download of a jazz album you think I will like!
Any questions please ask…
