TODO update with latest

Command API

Command api allows for remote control of your GMG. A few implementation notes

  • All endpoints are GET requests for now, to make them easy to debug in browser
  • Since endpoints command an actual thing which can be dangerous, a confirmation pattern is used. The first request to each endpoint returns a code and a link, following the link actually executes the command.

Here are the api endpoints

GET /command/power/on
GET /command/power/off
GET /command/power/cold-smoke

GET /command/temp/grill
GET /command/temp/probe1
GET /command/temp/probe2

GET /command/settings/pizza
GET /command/settings/regular

Status API

Basic API to get status of grill as stored in local state. Status is updated approx 1-5 seconds by pinging grill and waiting for response message. It's not reccomdend to use this for polling. Instead, talk directory to the database, see examples TODO

GET /status

Real-time API

Old notes

Overview

The point is a useful webapp for visualizing and tracking Green Mountain Grill cooks. This is a proof of concept which uses the work from https://github.com/Aenima4six2/gmg to decode the grill status which is sent over UDP when the grill gets the right command. This code aims to be much simplier to reason than Aenima4six2/gmg, and easier to get running and customize.

This spike write data to a CSV as a database (which proved to be more trouble than worth) and visualizes prob1 temp using a ascii line chart. Another command prompt can run a real-time dashboard, although its very buggy due to reading / writing to files.

To get started

  • Install deps npm install
  • Configure for your grill in ./config.js
  • Run npm run start
  • Additionally, in a new command window, run npm run dashboard
  • See CSV generated in ./data folder

Next steps

  • Use a real database to sync data from server to client
  • Test and reafactor the GrillStatus class
  • Add react front-end with proper graphs.
  • Try sending commands?
  • Debug profiles and what they are all about - do we need them if we can set a profile on this?
