The azure-cli-iot-ext is deprecated so I expect it'll be culled soon and this question retired. For those of our who get a question similar in the future I expect the answer to be az extension add --name azure-iot The legacy IoT extension Id azure-cli-iot-ext is deprecated in favor of the new modern Id azure-iot. azure-iot is a superset of azure-cli-iot-ext and any new features or fixes will apply to azure-iot only. Also the legacy and modern IoT extension should never co-exist in the same CLI environment.
