Reduced TESS light curves of eight ZZ Ceti stars found to be variables by the TESS data. We note that the light curve of HE 0532−5605 is on a different scale, and represents 13 sectors of data. We also denoted the values of the CROWDSAP keywords listed in the fits headers, which represent the ratio of the target flux to the total flux in the aperture.
