Steps to Reproduce (for Bugs)

• Use the following textual configuration files.

Items file

//Commands
String    HuesyncMode         "Mode"          <switch> {channel="huesync:box:LivingRoom:device-commands#mode"}
Switch    HuesyncActive       "Sync active"   <switch> {channel="huesync:box:LivingRoom:device-commands#sync-active"}
Switch    HuesyncHdmiActive   "HDMI active"   <switch> {channel="huesync:box:LivingRoom:device-commands#hdmi-active"}
String    HuesyncHdmiSource   "HDMI Source"   <player> {channel="huesync:box:LivingRoom:device-commands#hdmi-source"}
Dimmer    HuesyncBrightness   "Brightness"    <slider> {channel="huesync:box:LivingRoom:device-commands#brightness"}

@sebaruth

Thank you for the report. I'll have a look into this as soon as possible.

Thing goes offline, looses its api token and goes into configuration pending state

Probably same/similar problem as reported in #18062.

➡️ I'll analyze/solve the token problem and then I'll address this issue. If I understand correctly, this does not make the binding unusable for your purpose atm - right? Else I'll change priorities to get your configuration up.

[sebaruth]

Yes at the moment my use case does not depend on the dimmer item. So no need to switch priorities.

I have wrestled with the issue for the last day or so, and with this report and some digging find a usable workaround is to declare the item as type "Number:Dimensionless", instead of "Dimmer". This is what the GUI itself states, as well as the documentation, but the example says otherwise, so should be changed.
