Description

Hello,
Thanks for this lib! But, I’m having trouble configuring multiple sensors in the same code.

`
// List of Matter Endpoints for this Node
MatterTemperatureSensor mTemperatureSensor;
//MatterPressureSensor mPressureSensor;
//MatterHumiditySensor mHumiditySensor;
...

// Set initial sensors measurement
mTemperatureSensor.begin(sensor_getTemp()); // < Only one work perfectly :(
//mHumiditySensor.begin(sensor_getHumidity());
//mPressureSensor.begin(sensor_getPessure());

// Matter beginning - Last step, after all EndPoints are initialized
Matter.begin();
`
The Alexa Dot only recognizes 2 sensors, and their behavior is inconsistent.
Can you confirm if this is expected?

Thanks

  //mHumiditySensor.begin(sensor_getHumidity());
  //mPressureSensor.begin(sensor_getPessure());

  // Matter beginning - Last step, after all EndPoints are initialized
  Matter.begin();

@cfdev - I have tested the 3 endpoints running in a single ESP32-S3 with the Alexa Eco Dot.
After commissioning, only the Temperature and the Humidity are visible and both run as expected.
The pressure sensor doesn't work with Alexa.

This is because Amazon Alexa doesn't support the Pressure Endpoint:
https://developer.amazon.com/docs/alexaplus/smarthome/supported-matter-device-categories.html#sensors

Looking in the list of supported sensors, there is no Pressure sensor.
When I tested just the Pressure endpoint example, Alexa didn't complete the commissioning.

The Pressure endpoint works with Home Assistant, which is the one I have tested.

I'd say that for the Alexa Matter Environment, it would be better to only add Temperature and Humidity endpoints.

Hello,
thanks for this precision !

This is because Amazon Alexa doesn't support the Pressure Endpoint:
https://developer.amazon.com/docs/alexaplus/smarthome/supported-matter-device-categories.html#sensors

But even with 2 sensors only (temp and humid), Alexa didn't complete the commissioning and when I close and restart Alexa App,
there are 3 devices in the list. (as you can see attached)

When a Matter device has more than 1 endpoint, Alexa will create the same number of devices plus one.
This one device is just a "placeholder" for the main endpoint (with no function).

This is how Alexa works. If you try to build and execute the Composed Matter Light example that creates 3 different lights in a single Matter Accessory, Alexa will create 4 new devices, 3 for the 3 lights plus a fourth one that represents "the whole" accessory.

Deleting any of the 4 will delete the whole accessory. The same for your application.

This is my Alexa Screenshot with 3 lights + extra fourth "main endpoint device (dispositivo in portuguese)"
