ich versuche volumio über die API zu steuern. Die URL http://volumio_arbeitszimmer.local:3000/api/v1/commands/?cmd=volume&volume=plus im Chrome erhöht die Lautstärke um 5. Wie bekomme ich das in einem Widget realisiert ohne irgendwelche Scripte oder ähnliches zu bemühen. Das folgende Widget jqui - Icon HTTP GET scheint nicht zu funktionieren:
