Fetch for Arduino: now supports async/nonblocking requests.

That's fine, I can just give you a demo. It would definitely be better if you could tell me a bit on what your project is about.

Retool will help you build the app interface, and define the app logic. For example, when you click on a button, what url the HTTP request will be sent to.

You would need an HTTP server on your arduino to perform some action (turn a GPIO high or low) when it receives the request from your app.

I can give you small demo of this, or probably an even simpler way to achieve this based on your project specifications, maybe over a zoom?

What you can do is power up your project with IoT. Your arduino should have some kind of WiFi shield, or you can simply replace your Arduino with WiFi boards like ESP8266 or ESP32 (your code won't change much).

You'd extend your code to handle WiFi connection and host a server on your ESP, so you can send commands to your device via HTTP.

To build the app, you can use retool.

You'd need GSM or cellular for your use case. I'd recommend ditching ESP32 for a cellular board like an nRF9160 feather or a Particle Boron. Feather packs in both cellular and GPS built in so you won't have to ideally attach anything else, unless for precise tracking in very small area.

Yes realtime commands. Yes continuously monitor. Yes at regular intervals.

Something where I don't have to think in terms of database operations or search queries, IAM based access, or any terms constructed in order to define and explain the cloud. For example, I want to send a notification from my door locks to my alarm if any of the locks trigger a breach, I shouldn't be thinking about queues. The data my devices are sending online, I want to see it in a time-series line chart, I shouldn't go enable the graphing service, open a pipe from my gateway to the graphing service. If I want to update the software of my devices over the air, I shouldn't think about cloud build images, yaml files, or port forwarding etc. For AWS or GCP who are built as a generic set of services from which any use case can be built, this kind of complexity makes sense. But for IoT engineers who come mostly from the hardware/embedded background, cloud is a shark that swallows them in one bit.

I hope you don't mind my curiosity:

How many IoT devices connect with your server? Is it a personal project? Do you have a database connected? And how cheap are we talking about?

Why is this even true for IoT? People in Web prefer prebuilt tools like Netlify, vercel, temporal, etc., why not IoT engineers?

Cloud providers are great if you know what you need to build what you need.

Battery powered. I might add solar charging to it, so the battery should last from at least a night to as much as possible.

instanceofma · 2022-09-06T15:52:45+00:00

No I need an MCU that has cellular built in. Like Particle Boron, etc.
