hehe sorry my bad. Ok, so I hooked up everything last weekend and it works like a charm with the right converter! Then I discovered that my code was doing the queries too fast, so I had to put in a 500ms delay and with that, it was succesfully gathering the required information. So thank you very much for the SDM220 lib.

I'll update this reply with a link to my blog post as soon as I've finished it. But for this matter, I just had the wrong RS485 converter. ;o)

Hello,

would you mind telling me what was the wrong RS485 converter and what is the correct one ? i am using this one and am not sure where my problem is, i am using a 5v<->3.3v logic converter, assuming the MAX485 is 5v logic..
