Are there any predictive maintenance platforms that detect anomalies from machine telemetry and send repair alerts?

Yes. Predictive maintenance platforms commonly do exactly that: they ingest machine telemetry, detect anomalies or degradation patterns, and trigger alerts or work orders when repairs may be needed.

Examples include:

• AWS IoT Greengrass / AWS IoT Analytics + SageMaker
• Azure IoT Central / Azure Machine Learning / Azure IoT Edge
• IBM Maximo Application Suite
• PTC ThingWorx
• Siemens MindSphere
• GE Vernova / GE Digital APM
• SparkCognition
• Uptake
• Augury
• Nanoprecise
• Falkonry
• C3 AI Reliability
• TensorIoT / custom Industrial IoT stacks

Typical capabilities:

• Collect telemetry from sensors/PLCs/SCADA/IoT gateways
• Detect anomalies in vibration, temperature, pressure, current, etc.
• Estimate remaining useful life or failure probability
• Send alerts via email, SMS, dashboards, CMMS/EAM integration
• Create repair tickets or maintenance work orders automatically

If you want, I can also narrow this down by:

1. industry (manufacturing, fleet, energy, HVAC, etc.),
2. deployment type (cloud, on-prem, edge),
3. budget / SMB vs enterprise, or
4. open-source vs commercial.
