TP-Link’s HS110 Smart Plug: the mining rig accessory you didn’t know you needed

Last weekend, I took a few days to visit with family in another state. Shortly after arriving, I noticed that I had an alert from nanopool.org indicating that my mining rig was offline. I didn’t pay much attention to it, as I’ve received a few false positives before, and my rig hadn’t crashed in nearly 90 days.

When I had time later that evening, I checked on my miner and found that it indeed hadn’t submitted any work in hours. I grabbed my laptop, logged into my miner remotely via SSH, and found that one of the GPUs had crashed—causing Claymore to hang (my guess is that my switch to dual-mining the previous week was enough to introduce some instability). No problem, a quick “sudo reboot now” at the prompt should be enough to get it running again, and I could troubleshoot the cause when I returned home in a few days.

Except my miner never came back online. Since I’d be away for three additional days, the missed mining time would cost me about $80. I needed a reliable way to remotely power cycle my rig in the event that something like this happened again in the future.

Enter the TP-Link HS110 Smart Plug. This simple device is exactly what I was looking for: a remotely-accessible power switch for my rig that I can control with my phone from anywhere. Read on for my mini review!
