The UI of Jkool Cloud was easy to use in our project. It's very well documented so we were able to get up and running quickly with minimal training time required from support team. There are some features which requires additional configuration but that can be easily done by end user once they understand how it works. We have used this tool to create dashboards/reports about realtime metrics collected from devices connected via MQTT protocol using ESP8266 module or other sensors like temperature sensor etc., This has helped us monitor various parameters related to device uptime & connectivity status among others.
