Steps to reproduce:

1. Create IPMI monitoring item
2. Set sensors name HDD Temp 

Result:
sensor or control HDD Temp@[]:623 does not exist
Expected:
 item ":hdd.temp" became supported

if check JSON file created by ipmi.get  you can see that there are a lot of extra spaces in  sensor id, if take this id and create an item it works like expected

 

{"id":"HDD Temp        ","name":"(4.32).HDD Temp ","sensor":\{"type":1,"text":"temperature"}
