Charge / Locator

Is there a way that you can save the charging app info to a piece of equipment in the Equipment Locator App? I kind of thought that was the purpose of the Locator App. Is there a way to input the temp press readings into the Locator App? It would be nice if you could just save all of your inputs from the charging app over to the locator side of the app. Please let me know if this is possible.

No precisely , not too good

I bought this app to save time ,it is very easy to used but target superheat and cooling seems not so precisely. The customer support is very slow . I spent money for nothing.
