Monitoring and Controlling Electrical Appliances through Rule Engine in the Smart Office

In recent years, there has been an increasing interest in Internet of Things (IoT). Rule Engine is a developer tool to connect hardware devices to APIs (Application Programming Interface), a flow-based programming development with a UI for developers to use through a Web Browser. Node-RED runs on Node.js, making it ideal for use with Raspberry Pi as it consumes less resources. The file size is not large, and Node.js also acts as an intermediary for the Raspberry Pi to communicate with the web browser and other devices. This research is a development of the rule engine to monitor and operate office equipment. It was also shown that electrical appliances can be more easily controlled and operated by sensors. It can control the office environment in the desired conditions to become a smart office perfectly such as air conditioner, room temperature, room climate which includes the moisture value Carbon dioxide, TVOC, PM 2.5, and carbon monoxide. The values are stored in the Cloud and Edge Computing, and the results are very satisfactory. The results of this study indicate that the Rule Engine is the medium that connects sensors and office appliances, and effective. This finding has important implications for developing the smart office.
