hi again @petsie , have you ever received " warning: the hex string is not proper! Ignoring telegram!" like described here: (cul) warning: the hex string is not proper! Ignoring telegram! · Issue #279 · weetmuts/wmbusmeters · GitHub
As you know I’m using the nano-cul you recommend but I’m just receiving the error message above. Frederik (Wmbusmeters) suggest I use a im871a instead . But before desperatly buying one of those I wanted to hear if you know the error message .
