-Node.js Raspberry Pi Pellet Stove Controller
+# Hestia
+Node.js Raspberry Pi Pellet Stove Controller, named after the Greek virgin goddess of the hearth.
 
 # About
 This project seeks to replace the OEM control panel on a Lennox Winslow PS40 pellet stove with a Raspberry Pi. I will be utilizing a Raspberry Pi Zero W, relays, and switches already installed on the pellet stove. I chose a Pi Zero W for its small form factor, the lack of pre-installed headers, its wireless connectivity, and familiarity with the platform. I had previously used an Arduino Nano for a much more rudimentary version of this project and found great difficulty in making adjustments to the code. Additionally the Raspberry Pi platform will allow for expansion in the future to include IoT controls and logging of usage utilizing networked databases. The project will be written using Node.js and the rpi-gpio Node module. I've chosen Node.js for its familiarity as well as ease of implementation of a web server for future expansion.

 * Pause the script by creating a file named `pause` in the root directory.  
 * Reload the environment variables by creating a file named `reload` in the root directory.  
 * Quit the script by creating a file named `quit` in the root directory.
+
+# Roadmap
+* v0.1 - Get the pellet stove operating at a basic level. Only implements the auger relay and no safeties.
+* v0.2 - Implement safety switches and put the igniter and combustion blowers on relays controlled by the Pi.
+* v0.3 - Implement the HTTP module to allow controlling the stove from the LAN.
+* v0.4 - Implement usage logging with a SQL database.
+
+# Testing Procedure
+1. Launch app, check startup messages, check that it idles and pauses properly.
+2. Provide ignite command, observe if the igniter, blower, and auger get turned on. Make sure the igniter turns off after the pre-set time.
+3. Test that the following conditions cause a shutdown:
+    * Proof of Fire Switch OPEN after igniter shutoff.
+    * Vacuum Switch OPEN after igniter start.
+4. Test manipulation of feed rates.
+5. Test shutdown sequence.
