|
||||
* Modbus RTU relay boards
|
||||
*
|
||||
* Adds support for Modbus RTU relay boards, such as those from Waveshare or generic no-name brands.
|
||||
* They typically use the same modbus chip, therefore they share the same modbus instruction set and register map.
|
||||
*
|
||||
* The module allows control of up to 8 Modbus RTU relay devices, each with a configurable number of outputs.
|
||||
* The total number of outputs is limited to 32 reduced by the number of already cofigured power outputs in Tasmota.
|
||||
* The modbus connection settinga and relay devices are defined in a JSON template that can be loaded from
|
||||
* a file, rule, or script.
|
||||
*
|
||||
* Template syntax:
|
||||
* {"Baud": <baud>, "Devices": [{"A": <address>, "O": <outputs>}, ...]}
|
||||
*
|
||||
* Where:
|
||||
* - <baud> is the configured baud rate for the module (boards have 9600 by default)
|
||||
* - <address> is the modbus address of the relay device (1-247)
|
||||
* - <outputs> is the number of outputs for the relay device
|
||||
*
|
||||
* Note: These modules have harcoded N81 serial configuration.
|
||||
*
|
||||
* Example template for 2 devices with 4 outputs each ):
|
||||
* {"Baud":9600, "Devices":[{"A":1,"O":4}, {"A":2,"O":4}]}
|
||||
* Example template for 1 device with 8 outputs:
|
||||
* {"Baud":9600, "Devices":[{"A":1,"O":8}]}
|
||||
*
