Waking and sleeping a rig?
« on: 06 June, 2017, 09:33:15 PM »
I was bored and decided to look at renewable energy purely with a view to cutting costs...... Then one thing led to another and I got to wondering what would be a good way of only running rigs when the photo-voltaics/wind turbine were producing enough power?

With retirement not so far off now it is an idea that greatly appeals to my sense of scrooge

If you have thoughts or have heard of something similar I'd love to hear about it

On the subject of cutting costs OC, I seem to remember a few years ago you posted a suggestion that some of our members who enjoy very low energy and equipment costs could hire out their hosts for others to use for crunching, with the result they then get free heating and perhaps also make a little money. What became of that idea? It would surely work out a lot cheaper than Google or Amazon compute  /&\

A rather simple way I think that might work is putting PCs on UPS and monitor software on PCs to sleep and wake PCs as their power drops to certain levels. A quick search I found a Linux program that allow scripting and various controls. It will use one Network server to control other PCs. In the FAQ it talks about the PC coming back up after power down.

OC I do not know if this something that will be helpful but it at least shows what is possible under Linux with what you are wanting to do.
