How to integrate devices via REST API if Lua cannot provide access

[jayrock 10]

Folks,

 

over time I have optimized the integration of different appliances via REST; I could not access these devices directly from HC3 with Lua, mostly as I'm using components in other languages that are simply not available in Lua. The information in this forum helped me to get things done, hence I'm happy to share back. I could improve my code documentation skills at some point..... 

 

I hope this is useful starting point for others. You might recognize code snippets of some of masterminds here

 

I'm sharing here an example of managing a Comfee MDDF-20DEN7-WF dehumidifier. We can read status to be alerted when the tank is full, and send commands such as "Turn on" and Turn Off". The solution consists of:

 

1. Python scripts that access the devices, including Flask server to expose some methods to a JSON API

2. Dockerfile to containerize 1 & 2 so that it can run on different HW platforms

3. QA that picks up and controls via the API. I store state data in UserDescription field, and get notified when the water tank is full.

 

1. Python script "app.py" that access the devices

2. Dockerfile to containerize 1 & 2 so that it can run on different HW platforms. Put it in the same directory as app.py
