Hands-On MQTT Usage

Background

• Although the heartbeat system used in MESHdesk / APdesk allows for remote command execution there might be situations where you need the immediate command execution.
• Security is a big thing where I stay and with this hands on lab we will see how to make use of the MQTT implementation to switch outdoor lights remotely on and off.
• For this lab we have:
  • MESHdesk managing a mesh network that has the following hardware
    • 3x Xiaomi 4C Units
    • 2x Dragino MS14
  • 1x 4 Channel Arduino Relay Module connected to one of the Dragino units.
  • 3x outdoor lights connected to the 4 Channel Arduino Relay Module.
