Add capability in DPS to enable tagging on module twin

[OscarLee-MSFT]

Work with DPS to enable module level tagging for Device Update for IoT Hub groups during device provisioning.

For the moment we have an Azure Function that, with other few things, detects the tag provided by DPS in the device twin to push it to module twin's tags

Hi @jelalanne, we are covering the same problem. Can you give more insides on this?

Hello @geebinge , of course ! We have an Azure Function that it triggerred on module twins updates event, reads the new version's tags, and push the ADUGroup tag to ADU module twin if it is specified. We have few upgrades to do though, as for example detect when it is not there anymore, to remove it from the module twin.
