TLDR: Measures temp&hum in a configurable interval and with variable thresholds. Publishes to a mqtt server. Neopixels react to json data at a mqtt topic it is configured to subscibe. Single thread async implementation. Robust wifi and mqtt routines. Code at my github: https://github.com/worksonmymachine-de/iot_temptumsensor_ambilight This device is placed behind my main monitor and reads temperature…

Most code for simple IoT devices is a script with an endless loop with the code for the connected hardware like reading a sensor or polling something from the network followed by a delay. Keeping that pattern in mind helps to write new or convert your existing code for asynchronous execution. If you want to…
