01Measure, don't estimate
The node detects stoppages and their reasons, compares actual cycle time to ideal, and counts good versus rejected parts — the three OEE factors — from the machine's own signals. No clipboards, no end-of-shift guesswork.
02From metric to improvement
Measured OEE plus reason-coded downtime shows where the losses actually are, so improvement work targets the real bottleneck instead of the loudest complaint.
Common questions
The ones we're asked on every first call.
Run/stop state and stoppage reasons, a cycle or part signal, and a good/reject indication. Most machines already expose these over their PLC or sensors — the Pi node just reads and times them.
