Support for LSM6DSOX IMU sensor (Accelerometer + Gyroscope)

[mortenx]

Describe the component you'd like

I would like to request native support for the LSM6DSOX IMU sensor (by STMicroelectronics).

The LSM6DSOX is a modern 6-axis IMU (3-axis accelerometer + 3-axis gyroscope) that is widely available, low-power, and well-suited for embedded and IoT projects. It would be a very valuable addition to ESPHome’s sensor ecosystem.

Suggested implementation scope:
Even a minimal initial implementation would already be very useful:
I²C interface
Accelerometer output (X/Y/Z)
Gyroscope output (X/Y/Z)
Optional temperature sensor
Similar configuration style to existing IMU components (e.g. MPU6050)
Advanced features (FSM, MLC, FIFO, etc.) could be added later if needed.

What are your use cases for this component?

Why LSM6DSOX support would be useful

Very low noise and low drift, especially for static angle measurements

Excellent temperature stability compared to older IMUs

Low power consumption (suitable for battery-powered devices)

Commonly used in industrial, environmental, and motion-sensing applications

Frequently sold on small breakout boards similar to MPU6050 / LSM6DS3

A typical use case is tilt / angle measurement, where only the accelerometer is needed, but gyroscope data can be used for smoothing if desired.

Is there a public datasheet, documentation and/or schematics?

Anything else?

The LSM6DSOX is a modern, well-supported sensor from STMicroelectronics and would fit very well into ESPHome’s philosophy of reliable, local-first sensor integrations. Native support would benefit many ESP32-based projects that require stable tilt or motion measurements.

Thank you for considering this request!
