I’d replied in detail at the original post with the analysis on here so probably a better place for discussion I’d of interest :

EmonTx4 DS18B20 Temperature sensing & firmware release 1.5.7

Hiya, Looking through the schematics, I’ve got a potential solution to suggest / discuss that I think is worth considering. I’d have thought that the AVR should be capable of dealing with all these sensors fine, it’s just needing to disable interrupts to bit-bang that’s an issue which could be avoided if one used a hardware interface instead.
