Minerstat, especially with their OS helped me manage my rigs easier and remotely. The paid version with alarms, triggers and Telegram bot is worth the price! Come on, if you're mining it pays itself, since it saves you from errors and downtime.

Took a moment to get used to but the support staff is solid with a quick response time and theyll help you get your mining gear on track if you ever get stuck on something. From there its pretty straight forward, informative dashboard, every feature you can think of and tutorials on how to use them. not to mention the competitive pricing. you really cant go wrong with minerstat

very usefull when you want to keep an eye on your rig while away from it, you can even restart it, overclock, undervolt, check temps, and musch more while using the free edition. Honestly, i couldn't ask of anything more (except for a few things, but they are covered by the paid version)
