Reduce SIM overhead by optimizing Hookup API


Based on earlier suggestion, this was applied to 1.42 milker stall. Breast pump hook up messages are turned off when successful hookup is achieved. Feeding mask hook up is only done on start feed.

The current Hookup API creates a ping between Hookups and stall. That ping creates an on going sim resource drain. I would like to suggest optimizing the Hookup api to reduce the impact on the sim.
