Totally different subject. I have three Habs and three Goldrushes. I have them mixed with 3 running on a pc and 3 running on a Rpi. My issue is the Rpi. It seems to lock up and lose communication with the network after 3-4 hours. It needs to be physically reset. I use a data center so that really sucks. I have a similar issue with a pi on the old Drillbit miners. But for that one I bought one of those network enabled outlets that I can cut off power and restart power via the web. But those are not cheap.
My question is if anyone else has reset issues with their Rpi and if so how did you fix it. Bad SD card? Different hub or switch to router? Grasping here.
If you have something there capable of outputting RS232 (IE, computer 9 pin serial port) either natively or through a USB-serial adapter, you might be able to use these PDUs if you have 240V available.

They aren't networked so you control them through a serial terminal instead of SSH, but you can't beat $45 for a 10 port 30A 240V PDU. You can barely buy a big 240V power bar for that.
For the rPi, I am unsure since I've only used them a couple times to try and help out miners. I've probably never tried one for more than a half hour, but I can set up a couple boards over the weekend on one and see what happens.
