I explained that…
which is exactly what you’ve described.
The simple solution is to change your sketches, so that they all use the same virtual pins to send their data, and change your template so that it only displays data from one device.
You’ll then have three devices on your front screen in the app, and you can tap one to see the data for that device.
If you have a key piece of data that you want to display for each device (lets say it’s a temperature reading) then you can add this to each device “tile” like this…
If you need all the data in one place then you’ll need to have an additional device, and send the data to this device from the other three devices. This can be done with Automations if you’re happy with updates of 1 minute or more, otherwise you’ll need to use one of these options…
