Is it possible to put this info into SignalK?

[MigGat]

Hello everyone. On the electrical panel of my boat, there's the tipical gauge which can display both batteries voltage.
But it also can display the level on the 2 water tanks. Behing the panel there's a board with several connections (I assume 2 of them are from analogical sensors coming from the tanks).

Is there a way, probable using SensESP or similar, to put that info into SignalK?

Thanks!
