Question. So I was able to get a sensor pack in return for a bad controller. I have plugged it in and everything is showing up on the Mars app.

First question is do I keep the old sensors running. I kind of think I should as one tells the exhaust fan to turn on, but do the new ones already do that through the IHUB pro?

Second question is do I have to set up / program things in the app? For the sensor pack

And should I be worried about this white powder on my cord?

Thanks for any help in advance
