I use the duino as a modbus master and RF module. My Pi talks to it on serial.
I talk to temp controllers on modbus. I'll point you to that when I get it up
on the repo.

Alex,
The easiest way to do this might be to write a shim that reads/writes
the modbus and presents like an owserver on the other end. That way, it
would just look like a different bus to all the clients. You would need
some kind of config that sets the 1-wire id and the like. How much of

I recently wrote a simple software serial modbus master for use with an arduino
attached to an rs485 transceiver, the max3485 IIRC. Not sure what you're
talking with, but this is useful if you've got a serial port available. Haven't
quite gotten around to writing it up but it's here.

Hi Guys,
I’m in the process of upgrading my heating control system system that controls
a Wood-Fired boiler that provides hot water for in-floor (concrete) heating.
I’m now using a standalone Autonics TZN4M-BC4 PID controller that has a RTD
temperature sensor and 4-20mA output driving a Johnson
