Hi Team,

We are looking a Lua Script for NAC/SHAC for Daikin VRV Air Condition System Operation via Modbus RTU.

Kindly share the asked script.

Thanks,

Hi,

You would require a JSON file for modbus integration.  (Modbus tcp or modbusRTU would both use the same json file) 

Sorry to say I am not aware of a JSON for this ( if there is a JSON it probably is not "tested and validated" on a live system).   

I think from looking at some Daikin Specification docs that is is quite complicated as it requires supporting alot of bitmasking values.

The Docs suggest that 1 card is used for up to 16 units.
