Amazon IoT Greengrass Version 1 entered the extended life phase on June 30, 2023. For more information, see the Amazon IoT Greengrass V1 maintenance policy. After this date, Amazon IoT Greengrass V1 won't release updates that provide features, enhancements, bug fixes, or security patches. Devices that run on Amazon IoT Greengrass V1 won't be disrupted and will continue to operate and to connect to the cloud. We strongly recommend that you migrate to Amazon IoT Greengrass Version 2, which adds significant new features and support for additional platforms.

Amazon-provided Greengrass connectors

Amazon provides the following connectors that support common Amazon IoT Greengrass scenarios. For more information about how connectors work, see the following documentation:

Connector	Description	Supported Lambda runtimes	Supports No container mode
CloudWatch Metrics	Publishes custom metrics to Amazon CloudWatch.	Python 3.8 * Python 3.7 Python 2.7	Yes
Device Defender	Sends system metrics to Amazon IoT Device Defender.	Python 3.8 * Python 3.7 Python 2.7	No
Docker Application Deployment	Runs a Docker Compose file to start a Docker application on the core device.	Python 3.8 Python 3.7	Yes
IoT Analytics	Sends data from devices and sensors to Amazon IoT Analytics.	Python 3.8 * Python 3.7 Python 2.7	Yes
IoT Ethernet IP Protocol Adapter	Collects data from Ethernet/IP devices.	Java 8	Yes
IoT SiteWise	Sends data from devices and sensors to asset properties in Amazon IoT SiteWise.	Java 8	Yes
Kinesis Firehose	Sends data to Amazon Data Firehose delivery streams.	Python 3.8 * Python 3.7 Python 2.7	Yes
ML Feedback	Publishes machine learning model input to the cloud and output to an MQTT topic.	Python 3.8 Python 3.7	No
ML Image Classification	Runs a local image classification inference service. This connector provides versions for several platforms.	Python 3.8 * Python 3.7 Python 2.7	No
ML Object Detection	Runs a local object detection inference service. This connector provides versions for several platforms.	Python 3.8 Python 3.7	No
Modbus-RTU Protocol Adapter	Sends requests to Modbus RTU devices.	Python 3.8 * Python 3.7 Python 2.7	No
Modbus-TCP Protocol Adapter	Collects data from ModbusTCP devices.	Java 8	Yes
Raspberry Pi GPIO	Controls GPIO pins on a Raspberry Pi core device.	Python 3.8 * Python 3.7 Python 2.7	No
Serial Stream	Reads and writes to a serial port on the core device.	Python 3.8 * Python 3.7 Python 2.7	No
ServiceNow MetricBase Integration	Publishes time series metrics to ServiceNow MetricBase.	Python 3.8 * Python 3.7 Python 2.7	Yes
SNS	Sends messages to an Amazon SNS topic.	Python 3.8 * Python 3.7 Python 2.7	Yes
Splunk Integration	Publishes data to Splunk HEC.	Python 3.8 * Python 3.7 Python 2.7	Yes
Twilio Notifications	Initiates a Twilio text or voice message.	Python 3.8 * Python 3.7 Python 2.7	Yes

* To use the Python 3.8 runtimes, you must create a symbolic link from the default Python 3.7 installation folder to the installed Python 3.8 binaries. For more information, see the connector-specific requirements.

Note

We recommend that you upgrade connector versions from Python 2.7 to Python 3.7. Continued support for Python 2.7 connectors depends on Amazon Lambda runtime support. For more information, see Runtime support policy in the Amazon Lambda Developer Guide.
