Introduction

The NODA Modbus Gateway Addon acts as a tiny external brain-aid for application-specific energy controllers.

Whenever a controller cannot handle the logic required to return to zero from an affected state, this solution is needed to restore the default state on the controller.

For example, if an offset of the supply temperature on the secondary side is 6.5 degrees Celsius and the internet connection goes down. Then, the controller will happily continue with the same 6.5 degrees offset until internet connectivity is restored. For a worst-case scenario, this can take several days.

This addon's sole purpose is to add logic to the energy controller without putting it in the environment of an operating system that is frankly less stable than a microcontroller's.
