Initial fish light experimentation

This is an ESP-8266, programmed with a simple REST API that controls a two channel relay on these LED light bars.

This microcontroller can be slow to respond to requests. Consequently I have a Raspberry Pi (running my home’s web server) to serve up this webpage and cache the temperature/light statuses with cron. This makes the web app load almost instantaneously instead of requesting directly from the ESP on demand.
