Controlling a set of LEDs using a temperature value (obtained from OpenWeatherMap)

[dynamicdave]

Here's a link to the tutorial guide for my IoT students.

This week I've set them the task of controlling a set of three LEDs from a temperature reading (from OpenWeatherMap). The idea is to turn on the appropriately coloured LED depending on the temperature reading. The tutorial guide explains the shortcomings of sending a series of MQTT messages and suggests using a Rule Set (within the Wemos D1 Mini flashed with ESP-Easy firmware) to improve performance across the local area network.
