Staying on top of the emerging trend and technologies behind the "Internet of Things"

Hey everyone,

I’m a 3rd-year Engineering student, and I have to work on a project that showcases the use of IoT in Finance. I’m looking for guidance from anyone who has worked on something similar or has knowledge in this area.

If you know of any free resources, blogs, websites, courses, or research papers that could help me understand IoT applications in finance, please share! Also, if you have any project ideas or case studies related to this, I’d love to hear them.

Hello! I am a junior CIS student and I’m trying to get into IoT because it’s very interesting. I have a question regarding a project idea for my senior project and I need a professional I can talk to via DM to share my idea and get feedback on whether it’s actually doable

I read a post that says Dingtian multi channel relay is good for HaOS vs some other board.

I understand eap232 is a chip. Is it more than that? So the OS flashed should not be dependent on type of chip mostly. What is the advantage here with HaOS?

And are there any better multi channel (8, 16, or better 32 channel) relay hoards that work very easily with HaOS with less work?

I want to control LED strips and some for water shutoff automation.

Thanks.

I’m at a loss and trying to figure out a “dummy” everyday consumer fool proof solution for an consumer/prosumer mfr that I can offer to a few of my lingering frugal clients and several friends and family members who constantly barrage me with retail tech questions.

For the current problem I’m trying to solve, I have an elderly family member that I’ve installed Reolink POE cameras, Amazon Alexa, and TP-Link smart lights who now (kicking myself in the *ss for even opening her mind to smart home) wants the ability to have smart locks on her front gate and front door.

Here’s the environment:

• she’s tech illiterate
• will ask me what her passwords are
• android user
• finally got the basics of talking to and using Alexa

I need to find a smart lock mfr that I can utilize with Alexa and have their own app UX/UI be as intuitive to a novice user, have options for front door (slight weathering) and gate (full weatherproofed), offer a POE solution or hard-wired electrical power solution for her front door and try to figure out a solution for her gate lock that has the ability to charge via solar (she will never charge it, forget that it needs a charge and forever call me when it stops working to fix it or charge it)

Technically I need this baby proofed to be self contained, aesthetically pleasing (for ancillary wiring), usable through Google APIs or Alexa skills, and around the price point for something that can be purchased at Best Buy.

I’m asking for a unicorn here 😆

Open to suggestions or other methods, I’m ready to bash my head in over this futile project

Hi all.. I am a ECE Pre Final Year student... I have a course on IOT Based Systems this semester with a 15 point credit for a Mini Project which is self funded.... We want to do something different from stuff that college students usually do just for the grades...

Any suggestions on what problem statements/ purpose can we base the project around

We gotta submit by end of March

I ordered a couple of BLE gateways (with LAN, Wifi, BLE) from China, and a couple of tags. I am trying to report the hardware on a platform to visualize the data (tags movement on a floorplan). I can access the gateway through the OEM app.

1. What settings do I need to make on the Gateway to point it to a platform?
2. Looking for easy-to-use web platform recommendations, so I can route my gateways to it.

It would be great if anyone could list out the pathway that I can research to make it work, to help me get on the IoT ladder.

Thanks so much for your help!

Hello guys,
I am currently working on a project using a simcom Module to send and recieve data from a firebase database via http requests.
I am currently at the point that most things i try with at commands are working. I got it to send an sms to my phone. But as soon as
I try something regarding http requests. It doesnt work.
The last thing i tried is this
AT+CFUN=1,1 // Reboot module
AT+CPIN? // Ensure SIM is ready
AT+CSQ // Signal strength (must be >10)
AT+CREG? // Network registration
AT+CGDCONT=1,"IP","apn" // Set APN
AT+CGACT=1,1 // Activate PDP context
AT+CIPSTART="TCP","google.com",80 // Test connection
OK //response
STATE: PDP DEACT //response
CONNECT FAIL //response

I also tried
AT+CGACT=1,1
OK
AT+HTTPINIT
OK
AT+HTTPPARA="URL","http://httpbin.org/put"
OK
AT+HTTPPARA="CONTENT","application/json"
OK
AT+HTTPPARA="CID",1
OK
AT+HTTPDATA=15,10000
DOWNLOAD
//Here i should be able to enter text/ key value pairs but it doesnt work
OK

I dont know what to do anymore, maybee someone here has an example walkthrough code or some suggestion or thing i could try.
I would greatly apreciate your help.
Thanks in advance Felix Steck

I haven’t noticed Thingsboard being mentioned in this subreddit. Has anyone used it for their project?

It appears to be quite impressive, offering the ability to communicate with devices using various protocols. The documentation is excellent, and it’s open-source. Additionally, they provide an affordable Professional edition for large-scale operations and white labeling.

Thingsboard can be deployed in either as a monolithic or microservices architecture, with Kubernetes for high availability. It also includes SCADA functionality. Built in visualization tool, scripts, rule chains etc.

Hey all! I’m just spitballing some ideas here but would a Hologram SIM be a good fit for providing network to a system of WIFI enabled smoke alarms and water sensors? The alarms would be the only thing connected so I’m assuming data use would be extremely low but I have no experience with this.

I’m happy to explain WHY I’m trying to do this, but the ask is, would a hologram work in this use case?

Hi, I am a midly experienced software developer (5yoe) on both front and back. I am currently trying to morph into an IoT developer so I can learn. Besides the pay they offer is a massive upgrade from my current.
I've had a few projects that use this tech so I've made succesful connections to the main three sources of IoT managment in the cloud (gc, aws and az). I've connected passing all certification mess that happens on QoS1.

I am worried about the interview, as I never had an IoT interview before. I've told them I only have 1yoe in IoT, and I am a enthusiast about the topic having my own devices and a tiny proyect on the bathroom lights.

In your experience, or in your guess, what I might be asked?

[UPDATE]: It went amazing, I was extremely lucky on the questions. Mostly MQTT related, could answer almost all of them, asked if I could google the one's I couldn't. The interview lasted 30min more than expected, and the interviewer said he wanted me for the project so he will recommend me. I am so hopeful about this, thanks guys.

Have a Sunverge battery system at my house and the company went out of business. Heard from an old employee that I should be able to connect to the controller using an open web server, but I don't know the IP address. I've linked to the controller below; any body have any idea what the IP address for this thing is?

Hi All,

I am developing a lab for some software engineering university students working through a networking course. The course focuses on the application layer, my idea is to have them write custom packages from a client to a server. The packets would contain info about which led to turn on and the color etc… I will give them the specs and write the server code but I would much rather use a packaged solution for the led strip that would allow me to read their package and translate it to an api call rather than having to write my own. Any suggestions?

Hi guys, currently working on school IoT project and using the arduino uno r4 WiFi board. I am also using the Blynk IoT software for low code purposes for my arduino, however a problem I habe encountered is that my LCD I2C display doesn't work with it (Anything after Blynk.begin() will not display anything). May I ask if there are any solutions to this? Any help is greatly appreciated.

Hi. I have a small proj that needs to remotely monitoring and control an unattended device occasionally to stream data and set a few parameters. What i currently have is a cell phone (with data plan) and the device has an extra uart (ok to attach a uart-xxx). I would need to collect the data/configure the device from remote with a PC. wondering if there is any good solution for such config?

I've seen this a million times now. A smart fridge or lightbulb gets blamed for an entire network being hacked. I don't really understand how though. I get that IOT usually doesn't use encryption and the device itself can be hacked. Shouldn't anyone connected to the network be a security risk? Like, a casino got hacked through an IOT device a few years ago but they provide wifi to people in the casino. So if a hacker can go to the casino and connect to their wifi and not be able to do anything malicious. Then why are IOT devices the weak link?

My guess is would be that the IOT device was put on the same network as something secure and it used the same passwords. But that seems like a networking IT issue and not an IOT issue. Yet many times I have seen IT folks dumping on IOT for being insecure.

Can nothing be done to keep someone from connecting to ESP8266? Rolling codes, handshakes, rudimentary encryption at the software level?

Hello guys, hope you are doing well today!

I'm a landlord in Canada and I wish to add a wifi smart valve to each of my building's main water line. I would use Sedna valves by Sinope for this purpose. However, they are wifi...and I don't have wifi in my units. My idea would be to add a SIM router alongside the valve to give it wifi access to the internet. It wouldn't use much data, and I was wondering if you guys had any suggestion of what kind of router I should use (or any other suggestion on how to work this out) and what sim card provider would be best ? I currently have a Solis Lite device (with the included lifetime data) as well as a Cudy LT500 router for testing purposes, as well as a Simbase card.

I'm open to any idea!

I am getting into iot and honestly the worst/hardest part is unplugging and replying my inputs and monitors. I was thinking of use Ssh, or vnc I wouldn't even mind if I could just connect it to my main computer with USB of some kind

Hello all . I have to complete an IOT based project by the end of this calendar year which has been assigned to me by a professor at my uni . I have zero experience in IOT as my major is Comp SCI .

Could someone please guide me on how to get started and how to progress enough to build decent projects ? Please suggest some books / resources . Any advice is appreciated. Feel free to dm me with any advice/ suggestions/recommendations . Thank you for taking time out to read this long post ..

Hi Folks,

We're currently developing a field prototype using a Raspberry Pi 5 to gather real-world data for an application. I’m reaching out to the community to get your recommendations on USB wireless network adapters and mobile dongles.

Wi-Fi Dongle:
We need the capability to attach an external antenna to the dongle. While it doesn't need to support the latest Wi-Fi standards, it would be beneficial if it operates on both the 2.4GHz and 5GHz bands.

Mobile Dongle:
Although we're based in the UK, our prototype will undergo field testing in Kenya. Therefore, we require support for the following bands:

• 2G (GSM): 900 MHz and 1800 MHz
• 3G (UMTS): 2100 MHz
• 4G (LTE): Band 3 (1800 MHz), Band 20 (800 MHz), Band 7 (2600 MHz)

We're prioritizing reliability and compatibility for these prototypes, but any cost-effective solutions would be greatly appreciated as our funding budget is tight.

I really appreciate any advice or recommendations you could provide!

Thanks in advance!

I'm implementing Cisco URWB at the moment and would like to have power automation, visibility but also management. I know Meraki has the mt40 and wondering if there's anything equivalent on the catalyst side?

If there are OEM comparables, I would like to know what you guys are doing for power automation,visibility management on these remote APs.
