i try to set the volume of my denon 4308, with fixed volume its working, but i would like to dynamicly change the url with the value from item…
enclosed the item definition:
Number avr4308_volume “Volume” (gDenon) {http=">[*:GET:http://10.100.10.39/MAINZONE/s_mainzone.asp?textMas=-%2$&setMas=on]"}
i get the following error:
openhab.binding.http, component.id=33} | Bundle(org.openhab.binding.http_1.13.0.201808180110 [231])]
java.util.UnknownFormatConversionException: Conversion = ‘2’
whats wrong with that ?
btw. it seem that the receiver does not support the denon binding, is a very old one …
