Getting values from String items

I can see where my mistake is. I use the rule on a different device than the one where the corresponding Thing would be present.

On this device I use the Homematic Binding and added a thing.

### Signalstärke

homematic:HM-Sec-RHS:MEQ0461285:LEQ1253282:0#SIGNAL_STRENGTH*content_copy*

Number

*unfold_more*

### Niedriger Batteriestatus

homematic:HM-Sec-RHS:MEQ0461285:LEQ1253282:0#LOWBAT*content_copy*

Switch

*unfold_more*

Rotary Handle Sensor *unfold_less*

### State

homematic:HM-Sec-RHS:MEQ0461285:LEQ1253282:1#STATE*content_copy*

String

*edit* *unfold_more*

### Niedriger Batteriestatus

homematic:HM-Sec-RHS:MEQ0461285:LEQ1253282:1#LOWBAT*content_copy*

Switch

I’ll have to come up with something else. My devices exchange state and command via MQTT. As you can see here.

The binding was installed on the “server” and the rule was used on the “proxy”.
