I have a table with customers that I join with a fact table with sales, based on invoices.

What I need from my report is to get in first part the biggest value of sales based on the incoming order type (1,2,3,C,D) for a customer for last year. And in the second part to get the same but for current year. What I get as result from my current query is all incoming order types with the customer revenue made for each of them. I tried with outer apply as subquery to get only the top 1 value ordered by revenue descending, but in the result I get the same - For all order types the customer revenue. Please help! I hope my explanation isn't understood only by me (happens a lot..)

I was following this tutorial (https://docs.microsoft.com/en-us/learn/modules/create-your-first-iot-central-app/) In unit 4, I followed all the steps but what I could see was just a blank page like this

I am experimenting with AWS IoT greengrass V2. I am just following the manual that has the following python code:

I'm working on a Iot project. In my case, user can schedule a actuator command to run on specified time.( say on 08/06/2021 at 08.05 AM). This will be stored in mongodb database as a date variable. My requirement is to send an MQTT publish message to actuator at that specified time. Note that, this scheduling is not like interval scheduling. Each schedule will run exactly one time. I also need to edit the scheduled date time.

There is one way to achieve this. Each time user schedule a command, I can run a setTimeout function. But this is not a good practice and editing the schedule is difficult. So please help me to find a optimal solution for this. Thanks in advance.

I have a BeagleBone Black board and I'm using the below-mentioned image file. https://debian.beagleboard.org/images/bone-debian-10.3-iot-armhf-2020-04-06-4gb.img.xz

I aim to operate GPIO pins of this board with the c programming language.

To do so, I've gone through this link: https://beagleboard.org/static/librobotcontrol/installation.html

And after following all the steps according to this link the result I achieved is the same as mentioned in the checking functionality step [the last step] of this document.

Furthermore, I follow this document for c language setup: https://github.com/beagleboard/librobotcontrol/blob/master/docs/src/project_template.dox

and run this source code: https://beagleboard.org/static/librobotcontrol/rc_test_leds_8c-example.html

All these processes were completed without any error.

################################## Now I want to access the GPIO pins of the board. For that, I've prepared a basic code.

Let's take a pin P8_10 / GPIO2[4] for an example. So for that my code will be:

im starting with django and iot and i've decided to start (for learning purposes) an app that connects to my sensors attached to my raspberry pi.

The thing that im struggling is the next one:

I've done a class for my DHT11 sensor (temperature and humidity), and i've declared all values and wrote a method, which gets and prints the values of the sensor, and made a page where i show all the properties of the object, like "asigned pin" or the "name" of it; all fine until here. this is the class:

I'm trying to publish MQTT message to AWS IoT Core from Lambda on a different account.

Less assume that Account A is the one with the IoT core and account B is the one that has the lambda function.

On Account A: I created the following role type 'Another AWS account' using the account ID of B with the AWSIoTDataAccess policies:

I am simulating an Iot Device (Noise Sensor) in Azure IoT hub the code below works perfectly fine. However I want to simulate something closer to reality, where I can use different decibel ranges between different hours.

Something like this:

I am trying to run my Spring Boot application in debug mode (the normal run works fine), but it fails. I have tried to switch ports, I have killed all Tomcat processes and generally I have spent a lot of hours trying to solve it unsuccessfully. I work on Ubuntu. My JDK is 1.8.0_292.

The output is the following :
