Back when I was a student, we explored IOT and integration of sensors and stuff via boards like Raspberry pi , aurdino uno and Intel Edison. I know these boards can also do more than that.

I'm trying to encourage a few of my interns into these things but it's been a while and I'd like to understand the current trends and how to explore them. Thanks in advance.

Recently I started to look into IoT especially after my digital electronics class. I am doing computer systems and networking in Australia. My degree also has decent Linux and networking focus beside IoT, so I was wondering to pick one for the 3 to build good projects for 3rd year. This decision can determine alot, and I'm skeptical hence asking here, what are the thoughts

Hey guys,

I’ve been heavily focusing on IoT lately. I've built several hands-on projects using the ESP32, and right now, I’m diving deep into the cloud side of things using AWS IoT Core.

However, I recently talked to some mentors at my university, and their feedback honestly hit me hard. They told me that IoT isn't a viable career specialty on its own. According to them, it has largely been overhyped, there are very few jobs that focus purely on it, and companies prefer to just hire standard Computer Science students and teach them the IoT stuff on the job because "it’s easy."

Now I'm stuck doubting my path. I thought building a niche skill set in hardware-to-cloud integration was valuable, but now I don't know what to think.

• Is it true that IoT is mostly just overhyped buzz?
• Are there actually no "pure" IoT jobs out there?
• For those working in the industry, what does the actual job market look like for someone specializing in hardware and cloud pipelines?

Would love to get your honest thoughts and advice on this.

Hi everyone, I'm a software developer but completely new to embedded systems and electronics. As a hobby project, I'm trying to build my first IoT device and I'm looking for someone experienced with ESP32 to help me bring it to life. The prototype will roughly include: ESP32 4G SIM module GPS Temperature sensor Accelerometer Magnetic door sensor Small camera (event-based images) Battery-powered operation The firmware should: Read sensor data Send data to my backend API Trigger alerts based on events (motion, door opening, temperature, etc.) Capture an image during important events Be reasonably power efficient I'll provide all the hardware/components required. My budget is around ₹10,000, which I know isn't a huge amount, so I'm hoping to find someone who's interested in embedded systems and would enjoy working on an interesting project. If the scope needs to be adjusted to fit the budget, I'm happy to discuss that. If you're interested, please DM me with: Your experience with ESP32 or embedded systems Any previous projects (GitHub, photos, videos, etc.) Where you're based Your preferred framework (ESP-IDF, Arduino, MicroPython, etc.) I'm also happy to learn throughout the process rather than just handing everything off, so if you enjoy explaining things as we build, that's a huge plus. Thanks!

My needs feel modest to me: an outdoor unit to sense temp, humidity, and AQI, and to transmit that data wirelessly to me indoors, either to a dedicated unit or to my cell phone. Rechargeable batteries.

Does a market exist for products with this modest a scope? If so, I'll be a customer.

Some IOT's of 2.4 fail to connect with the Omada EAP's . My config is the OC200 controller , ER7206 , and 8 EAP's of 650,245,225 and 110 , spread around my home . Three floors , brick walls , concrete floors total about 5600sq ft . There are few devices on 5Ghz (laptops, mobiles, iPads ). All Media centers are connected by ethernet and all EAP's have ethernet backhauls. When I try to connect the errant 2.4 IOT's with my old router (Asus RT87 ) it is immediate. The security is WPA/WPA2-PSK/AES (tried the others WPA , WPA2) all extra's like band steering ,802.11r, PMF disabled. Separate SSID for 2.4 and 5 .I have a zigbee2mqtt setup with 50+ devices - Perfect .Any guidelines are welcome.

Trying to find a SIM for an alarm system that could use anything from 10mb to 300mb a month depending on broadband outage within the UK.

Ideally looking for a multi network option otherwise worst case I've seen the EE M2M 1GB is £2.95+vat a month.

Many thanks

Ok so, let me explain how things are going to add up and rough idea about my project!

The core idea about our project for hardware hackathon is going to be a SOS device for emergency situations like floods or landslides. a person takes a sos device with them while hiking and if its an emergency situation like landslide then he can push a button and send his/her location/emergency message to a central server and one feature we're thinking of adding is like the central server can send emergency messages to the user in an area where landslide or flood is occurring .Its a very unpolished idea. We'll be using mainly Lora module.

SO, this is my skeleton idea.

And I want to ask what are the components that are going to be used?

And How will it work ?

+ I am thinking of adding another feature where we can listen to the conversation going on so we can send evacuate team for them ?

Please help me!

Hello Reddit!

I have a mysterious issue that I cannot seem to solve on my own. I have a multitude of IOT devices in my home. At 3:18am on 6/27 the following devices ceased being able to access their cloud service but remained connected to my wifi. I know I have a lot of IOT devices. This stuff tends to slowly accumulate in this world. The Wifi food bowls may seem excessive but when you have 3 cats each with a separate diet, and one of them being 16, you do what you must. Also we travel and having the internet connected food bowls provides a surprising amount of certainty that your babies are fed.

3 PawsPik RFID food bowls

I have confirmed that these devices still function, and I can see them on my network via the router portal. My Router is an Asus RT-BE82U. It's a pretty standard network setup except for a PiHole configured on my NAS as the DNS. I did confirm that there are absolutely no blocks of any kind of the Pihole instance, up to and including disconnecting my NAS entirely to ensure this is not a factor.

Trouble shooting I have done so far,

Factory reset every device including the router,

Do a complete fresh network setup not using the Pihole with a different SSID and password

Switch router to an old one I have in the closet and the Xfinity router,

Use a network spectrum analyzer on my mac to make sure there is room in the 2.4Ghz band.

Creating a separate IOT 2.4Ghz network and trying to connect them there

A few other things to note,

I have a few other 2.4Ghz IOT devices that are completely functional (Roomba, GE washing machine, google home)

My other devices work flawlessly. I genuinely have no clue what else I could do besides just RMAing the food bowls, but that would not explain the rest.

The food bowls have a backup bluetooth LE connection to my phone so I am able to control them locally which is how I found out that they suddenly stopped working at 3am.

Any help is appreciated!

I’ve been working with MCP for a while and tried different tooling layers. Most solutions felt heavy or cumbersome, especially when it came to repeated calls and token usage with agents.
So I built cli-use — a lightweight tool that lets you instantly turn any MCP server into clean, easy-to-use CLI commands.
Main features:
• Add and run MCP tools with simple commands
• Create your own CLI tools directly from Python code
• Fast daemon mode for low-latency repeated calls
• Significant token savings (60-80% less overhead in agent workflows)
• Automatic shell completions and SKILL.md generation for agents
Quick example:

cli-use add fs /tmp
cli-use fs list_directory --path /tmp

You can also pipe outputs and use it naturally in scripts.
I’m still experimenting and improving it, but the reduction in complexity and token usage has been a nice surprise.
If you’re working with MCP and agents, I’d love to hear your thoughts:
• What frustrates you most with current MCP tooling?
• Would you like an easier way to create and run your own CLI-style tools on top of MCP?
Feedback is very welcome!

Looking for a Luckfox Pico/Pico Mini-style board, but with a few things Luckfox doesn't give me out of the box:

• Onboard camera (MIPI CSI)
• SD card support
• All protocol pins broken out (I2C, SPI, UART, GPIO)
• WiFi + BT onboard
• An actual audio/mic input I can wire a MEMS mic into (Luckfox Pico and Pico Mini don't expose the audio codec pins at all)

Planning to attach: a MEMS mic, a 0.96" I2C OLED, an IMU, a status LED, and a push button. Need it Linux-capable and roughly the same compact footprint as the Pico family.

Anyone running something like this in production?

Hey everyone,

I just finished my first year in Computer Science (1st year SI - Systèmes d'Information) in Tunisia and passed. Now, I’m hesitant about whether I should stick with SI or switch to ISI (Informatique et Systèmes Industriels) for next year. I really need some solid advice from seniors and expats who know the market.

Honestly, both fields interest me, and I’m fully ready to grind, work hard, build solid personal projects, and get internships in either path. That’s not the issue. My main goal is long-term stability and maximizing my earning potential.

Here is my breakdown of both paths:

• If I stay in SI: I want to target DevOps and Cloud Architecture. The money there is great, but the market for juniors right now is incredibly tough and oversaturated with developers. Will the infrastructure/Cloud market face the same massive saturation soon?
• If I switch to ISI: I want to get into the automotive sector (Car Tech, BMW, Bosch), robotics, or Edge AI (connecting AI models directly to hardware). It feels safer and more future-proof because it involves physical hardware and low-level engineering that AI won’t easily replace overnight. However, I’m worried that the job market for it is too niche/small, meaning fewer opportunities compared to pure software/Cloud.

My ultimate goal is to move to Europe. I plan to achieve this either through a PFE (graduation internship) during a 5-year engineering cycle, or by finishing my License and then pursuing an Engineering Degree (even if I have to do it in a private university like ESPRIT).

Given my goal of relocating to Europe, which path offers better long-term financial upside, stability, and market demand for Tunisian grads?

Thanks in advance for your insights!

Currently searching for ideas and open to connecting with people interested in building something together. If you’d like to brainstorm or collaborate, let’s connect!

I've been building CozyCritter, which talks to some Bluetooth hardware, and I kept hitting the same wall: I couldn't actually see what my device was broadcasting. The scanner apps I tried either buried the data I wanted or asked me to pay before showing me anything useful. So I did the side-project thing and built my own.

It started as a debugging tool just for me. GATT explorer, RSSI, manufacturer data, export to CSV/JSON so I could diff things between sessions. Nothing fancy, just the stuff I wished existed while I was stuck.

The part that surprised me: I have never been anywhere with fewer than 50 devices broadcasting BLE. My apartment, a coffee shop, a train, a parking lot in the middle of nowhere. Earbuds, TVs, fitness trackers, random sensors, things I genuinely can't identify. Once you can see it, you can't unsee it. The room is always talking.

It's on the App Store as BLEScanner if you want to poke at the airwaves around you. Happy to answer anything about the BLE side, it was a fun rabbit hole.
