DEVICEID/shadow/get does not work?

[Florian_Hansen]

Hey everyone,

I’m trying out mDash to remotely control my IoT devices. As I want to control them remotely via e.g. Azure I was following these instructions to setup remote monitoring:

Remote control via device shadow - overview

Device shadow is a JSON object that is associated with a device. It lives on a cloud, keeps device state and custom metadata. Device shadow is always available regardless whether an associated device is online or offline, via MQTT or REST API. Shadow JSON object has the following structure: state.desired - this is the state you want your device to have state.reported - this is the state your device actually has state.delta - automatically generated difference between desired and reported t…

When I am now on the MQTT page of my mDash overview, I am publishing a message to DEVICEID/shadow/get (in this case device1) and I expect to receive the full device shadow as a new message (topic: device1/shadow) but no message is sent. Please note that the messages that you see in the screenshot below my …/get message are sent by the device emulator as the state just changed.

Please refer to the screenshot attached.

What am I missing?

Thank you in advance
Florian

Currently, mDash replies with the shadow only if the message is sent by a device itself.

Thus, the MQTT client won’t trigger a shadow message.

This is a faulty behavior anyway, mDash should send a shadow regardless who sends a message. We’ll update the logic accordingly asap, will report shortly in this thread.

The logic is updated. Now you should see the shadow triggered by the MQTT client.

Thank you for the quick response and fixing this issue it works now as expected!
