Missing devices on VS code

[dean-sh]

Hello,
I'm using the extension on VS code and I'm missing some IOT devices.

• They do exist on Azure portal, but not in the extension list.
• I'm referring to the IOT devices pane under "Explorer" tab.
• Most of my devices appear correctly.
• When querying the list of devices using the toolkit, I am getting the same list that exist on Explorer pane, but it is showing only a 1000 devices, and we have more than that. Could that be the issue?
• I've reinstalled the extension and even tried downgrading.

Note: After some digging, this is probably related to Azure IOT hub limitations- Maximum number of device identities returned in a single call is 1000.

Hello - I'm having the same issue, I have over 1000 devices and now some are not showing up in vscode. Any updates or fixes for this?

This is by design. The extension uses the Node SDK to list devices from the service registry. Info on this call can be found at https://github.com/Azure/azure-iot-sdk-node/blob/master/service/src/registry.ts#L225, but the short answer is this call will only ever return <= 1000 records.
