	An arduino nano reads the buttons, drives the display, and switches a bistable relay. It also pulls a pin high when the fan is on, which is routed to a nodemcu used for interfacing with revspace MQTT (~~work in progress~~).		An arduino nano reads the buttons, drives the display, and switches a bistable relay. It also pulls a pin high when the fan is on, which is routed to a nodemcu used for interfacing with revspace MQTT.

			A nodemcu (ESP8266) reads the fan state signal and forwards it over WiFi to the revspace MQTT stream on topic revspace/intakefan/state.
			The state can be 'on', 'off' or 'unknown' when the connection between the nodemcu and MQTT is lost.

	Sometimes the need arises to temporarily shut off our forced air intake fan. In the past we simply pulled the plug on the motor, but that naturally led to people forgetting to turn it back on, until someone noticed an uptick in CO2 concentration a few days later. This box of plastic is intended to remedy that problem. Pressing a button will shut off the fan and set a counter. Another press will add more time to the counter. Once the countdown completes it will just start the fan back up, no fuss.		Sometimes the need arises to temporarily shut off our forced air intake fan.

Upon first press it will set a delay of 15 minutes, and each successive press adds another 15 minutes to the clock (up to a maximum off-time of 2 hours).

	It works fine as-is, but apart from the addition of some shiny baubles (in the form of sebastius' rgb knopjes) I do still have to improve the cable management situation. Also, opening it up is a bit of a pain at the moment, because the buttons on the front lid are hardwired to the pcb (which is itself mounted in a case that is firmly screwed to the wall). The upgraded buttons will get a connector.

	If the buttons are unresponsive, I suggest turning the controller off and then on again. You will find a switch on the top side, it controls the 5v supply to the arduino/esp. If that doesn't work, I suggest throwing your hands in the air and walking away quietly. Someone will report it, i'm sure.
