The absolute standout for me is how effortlessly I can spin up custom EXE sensors that pull live Modbus data straight from our legacy PLCs on the factory floor and correlate it with power draw on individual CNC machines. No other tool I’ve tried lets me do that without fighting through three layers of middleware or writing a full-blown agent. Last quarter I had one sensor flagging a 12% spike in vibration on a milling station at 2 a.m.—turned out to be a bearing starting to go. Fixed it during the next shift window instead of losing half a day of production. Review collected by and hosted on G2.com.

The hierarchical grouping for OT devices is still pretty manual. Every time maintenance swaps a sensor or adds a new actuator I have to go rebuild the tree structure by hand, and if you forget one sub-group the maps look like a jigsaw with missing pieces. It’s not a deal-breaker, but after a busy shutdown week it feels like busywork that should be smarter by now. Review collected by and hosted on G2.com.
