I have the same issue in combination with the Fritz 440 multi switch. No status of any of the 4 switches is shown.

Same for me as @colseven reported

With Fritz!OS 7.25 it worked. With 7.27 on 7590 again this error: [homebridge-fritz] This plugin generated a warning from the characteristic 'Target Temperature': characteristic value expected valid finite number and received "NaN" (number). See https://git.io/JtMGR for more info.
