Hello World, I am doing research in the context of Home Automation, to be more specific in the existing automation engines. Any kind of engines either standalone or parts of home automation systems are my research goal. I want to experiment with them, shortly if possible, so an important requirement is: They should be open-source! And secondary: they should be deploy-able to resource limited devices I have found quite a few rule-engines but not so many other types (scripting, dsls, etc.) Some examples are: 1) Newest automation/IOT software list 2) OpenHAB, OpenRemote, Vera, EasyRules, Domoticz, HomeAssistant, Drools, Logic4MQTT, etc. So, this is where I need your help to reference, mention or whatever any open-source engine (in the domain of home automation) that you have in mind. Thank you in advance.
