Hey, Orbitcoms,
As @alano mentioned, there is no way to store EEPROM data directly in the Dash – the thread he cites is definitely your best bet.
I’ve had decent luck sending to Thingspeak via a Hologram webhook – data directly to the Hologram Cloud, and there’s a whole bunch of tools to manage it from there. You then have the great added benefit of being able to see it directly on the Hologram Dashboard from there (rather than having to debug the whole thing on your Thingsboard).
Here’s the thread that got me started: Routing Rules, Webhooks and HTTP POST
