Hi,
Thank you very much for using Greengrass V2. The integration between client devices and shadow is being worked on right now. It will be available to use in a couple of months.
Until then, we advise the customers to create a new GG v2 component which will act as a bridge between the Client device and Shadow manager. This new component can convert the local MQTT message into the shadow operation using the GG v2 SDK. When deploying the new component, the customer should add some configuration in the MQTT bridge to translate the local MQTT messages to local PubSub messages (on which the new component is listening on). The customers should also add the specific configurations in MQTT bridge to translate the local PubSub messages to local MQTT messages.
eg MQTT Bridge configuration:
{
"mqttTopicMapping": {
"ClientDevice1Mapping": {
"topic": "$aws/things/MyThingName/shadow/update/accepted",
"source": "Pubsub",
"target": "LocalMqtt"
},
"ClientDevice2Mapping": {
"topic": "$aws/things/MyThingName/shadow/update/rejected",
"source": "Pubsub",
"target": "LocalMqtt"
}
}
}
Cheers,
Nikkhil
