Hi Guys,
I need to receive data from multiple devices (classroom). Each student device has a temperature, humidity, distance and an encoder.
I want to have a drop-down list which shows all the devices. When selecting a device, I want the data to be displayed on the Dashboard using the right interface depending on the data to display.
I have read this article about Multiple devices feeding a single gauge. In the article, there are 9 nodes for 3 devices for a single output. This is a no-go in my case. I have around 20 devices, 4 sensors which would mean more than a 100 nodes if I would be using the article example! And each time a new device is added I would need at least an extra 8 nodes...
How can I just have a drop-down list of devices and feed the data to the flow depending on the selected device?
Thank you
