MQTT & Zabbix Severity Cloud Lamp

Our cloud lamps are hacked up Ikea drömsyn's. They connect to an MQTT broker and reflect the current highest unacknowledged problem in our Zabbix monitoring system. Zabbix triggers run actions to publish the severity level to an MQTT topic. There are 6 severity levels in Zabbix with corresponding colours (white, and orange to red).

Here the Zabbix severity has gone from 0 (normal) to 5 (disaster).

Inside the lamp is an ESP8266 (ESP-01) and an addressable LED strip known as "Neopixel". The code on the ESP8266 is basically the Adafruit MQTT demo code, with a couple of changes to blink the LED strip.

Update March '23: We changed from our own code to using the awesome WLED project. It has much nicer and smoother animations!
