Seems interesting but I haven’t touched it yet to see how it works
If I haven't shared this before, my entire ASICS farm management is based on MRR.
But..... I don't use it to rent my rigs at all... (ie. set it to OFFLINE/NOT AVAILABLE FOR RENTAL)
My main purpose of using MRR is global proxy nodes (instead of setting up a proxy server at ISP side).
In the MRR central dashboard, I can monitor total hash, pools management, charting etc.
Downside: I lose the monitoring of individual rigs at ISP side. I am testing "anselal/antminer-monitor" for the S9 farm, since I have Teamviewer & VPN access to my ASICs at Cryptoboreas, GND and another ISP in Asia Pacific. As for the Avalons A721/A821/A841, these miners behave themselves quite well. I have to babysit the S9s more often.
The L3+s, D3s and other ASICs (Pinidea, Baikal) are also managed by MRR proxy nodes.
The GPU farms, do not use MRR yet since its hosted in my own private warehouse - 15mins drive from my house, and I can directly manage it easily.
It interests me because you can rent and mine on down time
