JSON monitoring of miner for Node-RED

[sothcott]

If you do http://127.0.0.1:3333/ you can get the console output of the miner as a web page that you have to keep refreshing.

Hidden in the page source is a little JSON string containing the following data, on my miner; result: array[9] 0: "11.3 - XMR" 1: "1473" 2: "3198;6233;0" 3: "793;818;819;768" 4: "0;0;0" 5: "off;off;off;off" 6: "83;60;84;61;75;43;77;44" 7: "xmr-proxy.xxxxx.org:3333" 8: "0;0;0;0" It's actually the 2nd line of the page source where it says {"result";

{"result": ["11.3 - XMR", "1267", "3036;5334;0", "793;655;820;768", "0;0;0", "off;off;off;off", "83;60;84;61;75;43;77;44", "xmr-proxy.xxxxxxx.org:3333", "0;0;0;0"]}

XMR: 08/20/18-16:21:19 - SHARE FOUND - (GPU 0; share value 0x00017d55)
Share accepted (1 ms)!

Just to make life hard there is no new line after the closing }.

To extract the data you must read the 2nd line up to and including the closing } and then stop. You can then parse the JSON string into an array. Element [3] contains your GPU hash rates as a string separated by ;. Like this 3: "793;818;819;768" so you have to split those up too.

I've managed to do all the above in Node-RED and now I have a little 4 bar chart I can look at on a phone showing my current mining rate.

It would help a lot if there was a separate port or mode for which the miner would just speak JSON.
