Review: Also ich habe mir das Gadget gekauft um zu sehen wie sehr die Batterie leidet wenn man nur noch Home-Office macht und 1x pro Woche 5 km fährt sowie um zu sehen wie hoch die Innenraum Temperatur vom Auto ist. Zum einen habe ich in der Wohnung das Gerät an einem Konverter angeschlossen um zu sehen wie genau die Temperatur Anzeige ist. Es waren meist 0,5-0 Grad Differenz. Das Gadget reagiert immer sehr schnell, wobei ich glaube das der Haus Außenkontakt eventuell nur einmal pro Minute nachmisst. Aber selbst wenn finde ich 0,5 Grad bei dem P/L Verhältnis noch gut. Die Voltanzeige funktioniert auch ganz genau. Da mein 12 Volt Anschluss nur Zündungsplus hat könnte ich nur das Testen. Hier verhält es sich so, dass er auf eine Dezimalstelle genau anzeigt. Einzige Einschränkung ist, dass er hier nicht auffinden sondern einfach die Hundertstel weglässt. Das es dir pessimistische Sicht ist, finde ich es besser so als aufzurunden. Also zumindest nach den ersten zwei Tagen bin ich zufrieden mit der anzeigt und das man die Aufkleber an der Seite einfach entfernen kann.
Review: I think the temp is a bit off. Would be nice if I could set it
