Sorry that I'm not explaining it correctly. Let me try again.
Customers are using different company sensors to get info from their warehouse, trucks, and so on. We fetch data from those sensors, push it to our database, and then Metabase pulls those data from our database and displays them via charts and graphs.
Now the customer gets a few more sensors for their fridge or warehouse and we need to pull data from those new sensors but the only way we can is if we know those sensors ID numbers.
This is where we need input data from customers. Once we get the sensors ID number we can start pulling data from them...to push to the database, which then Metabase uses it in it's charts and graphs.
