Hi! Any news according the M-Bus TTL Adapter?
I'm in the research phase myself, so take the following with a grain of salt.
Looks like the one pictured in the readme looks like it's a FC722 based adapter, and can be found on aliexpress, ebay or similar.
TSS721A based adaptors are also an alternative.
The circuit I most often see when searching around looks like it's based on this optoisolated one from the datasheet;
Search for mbus slave, you want something similar to these:
FC722
TSS721A
There are RS485 versions around too, make sure you pick the TTL serial (3.3/5V RS232) version.
Hi, great project! I can't find any info on the M-Bus TTL Adapter, do you have a source where it can be purchased or schematics so it can be built?
Thanks! /Lars
