This library allows to login into Meross cloud server, read the registered devices and open connections to the MQTT cloud server to get the data. The library tries to control the devices locally first (if "localHttpFirst" option is set to true), else will control via cloud server.

• Experiment with multiple MQTT connections vs only one and maybe optimize
• Find out how reading of Fan and Childlook works :-(

The library is partially based on the Python project https://github.com/albertogeniola/MerossIot, Thank you for this great basic work on how to connect to the Meross Cloud Servers
