IoTknit is part of the IoTempower framework. It allows to easily knit together devices reachable via MQTT (and hopefully later also for classic webrequests and websockets) of a network into an actual IoT system. It is therefore an IoT integration system (similar but much more barebones than Node-RED). It was called initially IntegrIoT since 2017, but that name was also adopted by BM Communications in 2022 and therefor had to be changed to forego any confusion or even potential legal conflicts for this open source project here.

It is a Python module and can be installed to your local Python environment the following way:

Without cloning:

pip install --upgrade git+https://github.com/iotempire/iotknit

After cloning this repo (from the repo directory):

pip install --upgrade .

For building, run:

pip -m build

A simple example how to connect a button node with a switch is here:

from iotknit import *

led1Status = False

init("localhost")  # use a MQTT broker on localhost

prefix("led")  # all actors below are prefixed with /led

led1 = publisher("led1")  # create a Thingi interface that publishes to led/led1

def button1Callback(msg):
   global led1Status

   print("received: [button]", msg)

   if (msg == "down"):
      led1Status = not led1Status  # toggle status of led

      if (led1Status):
            led1.publish("set", "on")  # publish updated state
            print("sending: [led1]", "on")
      else:
            led1.publish("set", "off")
            print("sending: [led1]", "of")


prefix("button")  # all sensors below are prefixed with /button

button1 = subscriber("button1")  # create a Thingi interface that can have
                                 # subscribes only to button/button1
button1.subscribe_change(callback=button1Callback)

run()  # you can also do a while loop here call process() instead
