Hello,
I am writing a simple HomeIOT application that my local ESP8266 devices with DHT22 sensors will send their data to every few minutes. It will have a dashboard (currently in materializecss) that allows uses to add devices with a name, passcode and the fields for the data being sent. I have easily made the devices and dashboard however I’m currently a little stuck and needing assistance for the layout.
I was planning on utilising mongodb to store the data using a simple rest API. This would allow each device to post to a url which would then verify the name, the code and then push the fields into a new document that would be rendered in the charts.
However, I am unsure how to dynamically add a collection when a device is made, such that each device has its own collection for the data being sent.
Should i dynamically make a collection that can have data added to it… i.e.:
Device name: ‘Inside_DHT22’ … then i was considering making a collection something similar to: ‘data_Inside_DHT22’ which i would then call in the rest API.
I was hoping to make similar collections for every device made, as to avoid mixing data for multiple devices in a single collection.
Is there any advice you can give me on the best way to structure this? or would one collection suffice with each document containing a name field to identify the device it is from?
If you were to suggest making a collection for each device ( assuming they push new data every 5 minutes, and runs 24/7), and if so, how would is the best way to do that when the number of devices being added is unknown?
Regards,
Jeremy
