1: Ability to download sensor data. As I understand it, the controller stores a few days of data on the phone. It would be great if we could download that in .csv format.

It's available. Go to board setup by holding the device button. Then go to sessions and click on the required session to upload

Maybe in the future.

This is good. We are working on it.

2: Ability to connect many devices to one graph. I tried setting up two ESP8266's with the same program and token but with different variables for the graph. I would like to have a few temp sensors around the house all showing up on one graph.

3: Notifications.

Thanks for a great product!
