Help understanding IoTHubDeviceClient in distributed modules
Hi, I have a hard time wrapping my head around how to work with custom developed modules and connection strings. To make things easy, I've taken one of the Python scripts from the SDK examples on GitHub (the one that sends simulated temperature and humidity values). The example mentioned uses IoTHubDeviceClient.create_from_connection_string(CONNECTION_STRING) and the send_message(message) to deliver it's values. This works fine and the data keeps coming in. However when I build a module from this and don't want to include a static connection string I can't seem to understand how this is done. Surely there's a corresponding way to get this dynamically populated or handled by the edge device. I just can't find any info on it. My guess is that you are suppose to use IoTHubModuleClient.create_from_edge_environment() instead and use that but I can't seem to get that to work. Any input to what achieves this? The aim is to be able to push the same module to multiple edge devices connected to different IoT Hubs and to do this I don't want to include a connection string.
IoT Solutions, a proposal to help creating PaaS solutions faster
Hi all, You can find here a proposal to try to go faster and better when it comes to building IoT solutions (PaaS). https://github.com/jonmikeli/iot-accelerator The main purpose is to help to focus the effort on creating value and maximize the use of the potential/capabilities/features provided by Azure IoT. The repository contains a set of scripts (bash, ARM) and source code (C# - Azure Function and REST API) that build part of the logic modules of an IoT solution.
Time Series Insights (Preview): errors modelled as categorical variables slow and max. 100.
A customer has a device which can generate errors. The IoT data is processed by Time Series Insights (Preview) in Azure. I modeled the errors as an categorical variable. But I ran into some problems: - the device has 370+ different errors and TSI has a maximum of 100 categories. - the TSI Explorer becomes at times very slow - the TSI Explorer does not show the original (error) value. What is the best way to model a error value with more than 100 different labels in TSI? Edit: TSI Explorer was very slow in Chrome, but it's ok in Microsoft Edge.
Preloading IoT Edge containers into a device
Hello. I wonder if it's possible to copy the docker containers to a new device which has a matching deployment setup in IoT Edge hub, so the device can be shipped without needing to download everything. Is this possible without tainting the IoT edge footprint so it doesn't remove containers etc? For example if there's a crucial container that needs to be running as fast as you turn on the device, this is very useful.
Smart heating
Hello, Sorry for posting here, I have a new account and I can't post a new topic yet. I have a question, and need your opinion or solution if you have one. I work in a company that is trying to make smart heating systems in building using IoT and more precisely Microsoft Azure. I followed the tutorials that Microsoft Azure offers, until it came to PowerBi... And i found two elements that made me lose alot of time.. First element: Sending data directly from Azure Storage Blob doesn't work on PowerBI, i had to recreate an other query to make it work but it took lots of time to find the solution on the blog. Second element: I'm surprised that there is only commercial units for data in PowerBI. Isn't it supposed to be monitoring devices in a building as well? Well i hope that i didn't annoy you with my questions but you seem more experienced that me, so i decided to ask while waiting to be able to post my own topics. PS: Azure IoT central is very limited and not smart at all... i had to use something else like PowerBI.
Why I don't see "properties"-column on my Azure-IoT-Central Device?
I just started learning Azure-IoT-Central yesterday. I tried the demo "dtmi:com:example:Thermostat;1" It has a writable property. I can see: "About, Overview, Command..." But why I don't see the "properties"-column? (Please see screenshot) Any hint? Thanks! Jadv
