  A sample of 4 thousands Gaia sources with apparent $G$-band magnitudes of
$<17$ and trigonometric parallaxes of $>3.33$ milli-arcseconds were
cross-matched to the Transiting Exoplanet Survey high level science products
and the Full-Frame Images in order to extract the light curves of possible
white dwarf variables. Most of the targets in the sample were observed in at
least 27-day observing cycle with 30-minutes cadence. Based on Lomb-Scargle
periodogram constructed from de-trended light curves, more than 600 sources
have indication of periodic variability. This paper presents the early results
from the identification.
