I'm trying to make a car parking type of application and I need to send the following data to IOTCENTRE Checkin-Time:timestampl CheckOut-Time:timestamp Car-Registration-Number:TEXT/alphanumeric
The first two can be simply send via sendEvent as telemetry and iotCentral will plot them on a graph for me. However, I can't find a way to send the alphanumeric data/number plate. The approach I have in mind is updating the device twin properties by adding a "RegistrationNumber" property in my device templates on iotCentral but that approach just feels stupid. Is there a better way to do it?
PS The whole reason I am doing this with IOTCentral to save myself from creating a front-end for the application(which iotCentral provides already). I know you could send text telemetry and even forward it to a storage account blob/structurd. What would be the right approach to do the same with iotCentral(and having the data stored in blob/DB to retrieve later for CRUD operations.
