Azure IoT

This forum is to get feedback on the new IoT services: Azure IoT Hub and Azure IoT suite. This forum will help the engineering team collect feedback from our customers and users and help us understand and prioritize the roadmap.

  1. Allow interaction between IoT Hub routes and Event Hub which resides in a Vnet

    Currently it is not possible to communicate between IoT Hub routes and an Event Hub (integrated in a Vnet), as described here: https://docs.microsoft.com/de-de/azure/event-hubs/event-hubs-service-endpoints#next-steps
    Please make this feature available, so that we can fulfill our internal company security rules.

  2. Enable per device message throttling capability

    From the cost and cyber security perspective, its ideal to set message throttling/quote per device instead of at the IoTHub Level. there is a possibility that one rogue device eating the complete limit of one or more IoTHubs if we cant throttle per device.

  3. iot hub routing, publish device twin tags in message properties

    message routing is an extremly powerfull mechanism. but once the message is routed on a custom endpoint it will be really powerful to have some device twin tags promoted as message properties.
    i.e message.body.temp>50 goes in alert queue but promote the $twin.tags.devicelocation and $tein.tags.customerId in the properties. In this way a backend application can Immediately use this information without retrieving it from another system

  4. Get an alert when reaching the max quota of the IoT Hub

    Hi,

    Sometimes we send more messages than the size of the IoT Hub allows. We'd like to be able to receive an alert when this scenario occurs.

    The current Alert system for IoT Hub allows to setup a dynamic threshold to any metrics but there is not option to limit the quota.

    Thank you.

  5. Add metrics related to messages process status under traffic shaping

    Hi,

    From Azure documentation: "To accommodate burst traffic, IoT Hub accepts requests above the throttle for a limited time. The first few of these requests are processed immediately. However, if the number of requests continues violate the throttle, IoT Hub starts placing the requests in a queue and processed at the limit rate."
    https://docs.microsoft.com/en-us/azure/iot-hub/iot-hub-devguide-quotas-throttling

    In these circumstances, some messages are not sent immediately.
    In order to know what is happening to our messages, we would like to get the following metrics:
    - The number of messages not sent because of the IoT Hub size limit
    - The number of messages…

  6. allow users to log any type of communication between cloud the device payload into Azure Diagnostics in log analytics for debugging

    It would be great if we could log the messaging payloads into log analytics between cloud and devices (both directions) for debugging purposes.

  7. IoT Hub DeviceTwins to store device public ip address

    If the default metadata of the DeviceTwins document could store LastKnownPublicIPAddress value, that would help some customers to further do maintenance on their devices.

    This request came from one of our customers.

  8. Add access to device twin in module message enrichment for Iot Hub

    When sending events from within an iot edge module, the $twin in the message enrichment refers to the module twin. This means I cannot add things like tenantId that is managed on the device twin. Is it possible to give access to the device twin in this situation?

  9. IoT-Central will disconnect and reconnect again in an exact 48 mins

    It seems due to the MQTT version issue, the SAS token cannot be updated with live connection when it's expired. It makes a weird situation that our device has to re-connect in every 48 mins...That does not make sense at all. Please help to fix this.

  10. Add system property SessionId to the Message

    Add a new system property SessionId to the Message (Microsoft.Azure.Devices.Client) to enable usage of
    https://docs.microsoft.com/en-us/azure/service-bus-messaging/message-sessions in case of following path of messages: device -> IoT Hub -> Service Bus Topic -> Azure Function

    Service bus demands system property, but does not take into account custom properties.

    Without such support it is almost impossible (or demands additional effords and resources) to implement sequential messages processing using Service bus

    Discussions of this problem:

  12. Allow stream Analytics job query defined in Python script.

    Stream analytics is very powerful concept and to get much from this service a python based query will handle real business scenario better.

  13. Missing iOS SDK support for DPS?

    Although the iOS client SDK claims to support the IoT Hub, the support for the device provisioning service (DPS) is missing?

    How can iOS clients with X.509 self signed certificates register on IoT Hub via the DPS?

  14. Modbus TCP protocol not allowing permissions/control for function code

    Modbus TCP protocol is not allowing for permissions or constraints to be set on Modbus function code and internal coils and registers. Access control is required for production scenarios to deny or constraint specific addresses of coils or registers. Ability to apply permissions to functions is useful.

  15. Modbus TCP Aliasing: mapping Unit IDs

    Modbus TCP has Unit ID and IDs and multiple RTUs can be connected to single device. However, it is not always possible to have unique IP addresses for IDs. Since Modbus TCP identifies a by MBAP header Unit ID, it would be useful to map Unit IDs to IDs and use aliases for mapped IDs.

  17. RFC 6066 max fragment length

    Please support the RFC 6066 standard for negotiating max. fragment lengths. I have now encountered a lot of scenarios where IoT devices receive too large packets.

  18. MQTT over TLS to servers outside Azure IoT Hub, per MSFT's open Cloud pledge

    Enable MQTT over TLS (using remote attestation certificate) to connect to MQTT brokers running on servers other than IOT Hub, per the attached Azure Sphere "Open Cloud" pledge. HTTPS is inadequate for many IoT use cases.

  19. I'm trying to run an Azure IoT intro class at Collin College in Texas. Need Microsoft help

    I purchased two official Adafruit feather HUZZAH Azure IoT Starter Kits. The IoT Hub creation script has been changed. Where can I find the current script?

    Also, do you have an academic program? Why can't I choose F! subscriptions for my class? Do you have a working script for my project kit or any other kit?

  20. Configure Properties on IotHub doesn't work

    I ran the following command
    az iot hub update --name {your iot hub name} \
    --set properties.storageEndpoints.'$default'.connectionString="{your storage account connection string}" in a bash script and I receive

    Couldn't find '$default' in 'properties.storageEndpoints'. Available
    options: []

    I just followed the steps provided https://docs.microsoft.com/en-us/azure/iot-hub/iot-hub-configure-file-upload-cli to enabled file uploading for my iotHub instance.
