Using association groups can allow you to eliminate polling, providing instant feedback of a device state change without unnecessary network traffic. The ZW31 supports 1 association group. ### Group 1: Lifeline The Lifeline association group reports device status to a hub and is not designed to control other devices directly. When using the Lineline group with a hub, in most cases, only the lifeline group will need to be configured and normally the hub will perform this automatically during the device initialisation. The association group supports five nodes and lifeline function Association group 1 supports 5 nodes. ## Technical Information ### Endpoints #### Endpoint 0 | Command Class | Comment | |---------------|---------| | COMMAND_CLASS_NO_OPERATION_V1| | | COMMAND_CLASS_BASIC_V1| | | COMMAND_CLASS_SWITCH_MULTILEVEL_V3| Linked to BASIC| | COMMAND_CLASS_ASSOCIATION_GRP_INFO_V1| | | COMMAND_CLASS_DEVICE_RESET_LOCALLY_V1| | | COMMAND_CLASS_CENTRAL_SCENE_V3| | | COMMAND_CLASS_ZWAVEPLUS_INFO_V1| | | COMMAND_CLASS_CONFIGURATION_V1| | | COMMAND_CLASS_MANUFACTURER_SPECIFIC_V1| | | COMMAND_CLASS_POWERLEVEL_V1| | | COMMAND_CLASS_FIRMWARE_UPDATE_MD_V1| | | COMMAND_CLASS_ASSOCIATION_V2| | | COMMAND_CLASS_VERSION_V2| | | COMMAND_CLASS_MULTI_CHANNEL_ASSOCIATION_V3| | ### Documentation Links * [ZW-31 V3.0](https://opensmarthouse.org/zwavedatabase/1148/reference/ZW-31-Mamual-V3-0-2019-5-30.pdf) --- Did you spot an error in the above definition or want to improve the content?
