currently i see no solution and maybe you are able to help. I try to set the stae of an item based on information from another item without a rule. Example:
There is an item (Type number) that holds the batterylevel in percent and from this i like to create s switch item that is on if the batterielevel is low (below 10%).
Doing this with a rule is easy. With mqtt items it is easy too using a transformation. But how could this be established with other items
It is one of the reasons why I wish transformations were generic and not implemented by the specific bindings. There might be a technical reason why that isn’t the case, but if transformations worked for ALL bindings, like you say with MQTT, this would be easy.
