Catalina does IoT with MQTT

 

Catalina Technologies Integration Toolkit is IoT ready with strong MQTT connectivity.

Catalina is IOT Ready-smaller

You can subscribe to feeds on existing MQTT brokers, publish to feeds on MQTT brokers, and the Catalina Toolkit even has it’s own built in broker that can be published to which maps and routes the MQTT packets to other systems.

Features:

Subscribe to feeds

Catalina Integrator can subscribe and listen to feeds on existing brokers.  This allows you to monitor data coming in from devices and map that data to other systems and storage.  If you don’t have an existing MQTT broker, Catalina Integrator has a built in MQTT broker.

Data mapping and route to other systems

When data is received from a monitored feed, Catalina Integrator can then push it to a script and redirect it to other systems such as field service, ERP, CRM, Support, and Help Desk systems.

Scripting

Send data to an MQTT broker

So far, we have been talking about subscribing to MQTT feeds and acting on them.  But what if you need to send data to a device through MQTT?  Catalina Integrator allows you to redirect any data to an MQTT broker feed.  This means that you can send messages and control devices out in the field directly from your Service, Helpdesk, Dispatch, CRM, ERP, or other system.  Below, is an example where we are turning on lighting based on an event in the service call system in Dynamics SL.

Scheduling MQTT Messages to io.adafruit.com from Windows Task Scheduler

Often times, I want to send an MQTT message to a device so that it can automatically do something on a timed basis.  Example, say I want to turn on my greenhouse lights for my seedlings in the morning, at a certain time, and then turn them off in the evening at a certain time.  If you are using Adafruit, it has a trigger that wakes up every so many minutes, hours, days, weeks.  But, I want to have things to trigger at the same time every day.

I could use cron on one of my linux boxes.  But, in my case, I wanted to use a windows box to do the time triggering.  An easy way to do this is to use Windows Task Scheduler that comes with Windows.
