smart meter webthing

A webthing connector for smart meters

This project provides a smart meter webthing API. It provides the software to connect an IR USB sensor

The smart meter webthing package provides an http webthing endpoint that supports smart meter consumption values over http. e.g.

# webthing has been started on host 192.168.0.23

curl http://192.168.0.23:7122/properties 

{
   "current_power": 389,
   "produced_power_total": 3314.7,
   "consumed_power_total": 259784.2
}

To install this software, you can use the PIP package manager as shown below

sudo pip install smartmeter_webthing

After installation, you can start the webthing http endpoint in your Python code or from the command line by typing

sudo smartmeter --command listen --port 7122 --sport /dev/serial/by-id/usb-Silicon_Labs_CP2102_USB_to_UART_Bridge_Controller_0051-if00-port0

Here the webthing API will use the local port 7122. Additionally, the device address of the IR sensor must be set. To configure the device address, see setup device.

As an alternative to the list command, you can also use the register command to register and start the webthing service as a systemd device. This way, the webthing service is started automatically at boot time. Starting the server manually with the listen command, as shown above, is no longer necessary.

sudo smartmeter --command register --port 7122 --sport /dev/serial/by-id/usb-Silicon_Labs_CP2102_USB_to_UART_Bridge_Controller_0051-if00-port0
