Display Signal K data on Kobo Simple browser ?

[NahanniV]

I have a couple of waterproof sunlight viewable Kobo Aura H2O e-readers aboard.
They have a built in browser.

I am running the OpenPlotter Distribution (with Signal K server) on a Rpi.

The only SignalK webapp I have found that can be displayed in the Kobo browser is Sailgauge, but it refreshes so often that it is not pretty on the E-Ink display.

I'm wondering if there is a simpler WebApp that might work with the Kobo browser ?
I'd be happy with something that would display SOG, DPT, AWS, AWA as text.

Thanks,
John Middleton.
