Modbus RTU to Emoncms Influxdb Thingspeak
Modbus to Emoncms. The ModWRT is a Modbus RTU unit to interface with one or several RS485 RTU devices. The ModWRT sends a predefined set of registers value to a server for data logging and display.
The end server can be either of type Emoncms, Influxdb or Thingspeak.
All communication and dataflow parameters are configured using a web interface.
Technical Specifications
- RS485 port
- Ethernet port
- Integrated Wifi
- Micro-usb Power supply
- Operating system: OpenWRT 14.07
- Flash Memory: 64MB
- Dimensions: 90x60x30mm
- Enclosure: Aluminium case
- Optional Wifi antenna
Software
The ModWRT web interface is build within the OpenWRT web interface.
There are three main functional area which are:
1/ RTU's definitions
2/ Servers definitions
3/ Dataflow configuration (ie which data goes where).
The web interface is briefly described below. See more details in the user manual.
1. RTU definition
All Modbus RTU devices can be configured on one single page using Slave ID and communication parameters (baud rate etc).
2. Stream to Emoncms, Influxdb, Thingspeak definition
Internet of Thing (iot) servers can be configured on this page.
3. Dataflow Configuration
This page will configure all dataflow combination.
A single dataflow can query different RTU unit to send combined data onto a single export.
As an example the above example will display the following data on Emoncms.
