@n3ro Ah yes… it measures whether you have been eating lots of Bratwurst und Zwiebeln

Hey @n3ro ,
I know this thread is quite old, but just stumbled upon. The one Freshmatic I got from the link above is without a VOC sensor and I can’t seem to find one with. Do you know if they still produce these Freshmatics with VOC sensor? The sensor itself from ams.com cost me around 55 bucks and I’m not willing to pay that much for a sensor
