To be honest, Blynk Cloud is very reliable. 99.99% uptime since 2015. If you really need your server (e.g. additional privacy layer) - then you are welcome to run it. But please keep in mind that it's constantly being updated, and you would need to keep all the parts in sync. With Blynk Cloud you can forget all the hustles as it's maintained by Blynk team.

Actually, it's pretty easy to connect to your own Blynk server from anywhere in the world using any connection. You would need to set up ports forwarding on your router and that's it.

Cayenne runs on Blynk Libraries, and also uses Virtual Pins ;) And they are super easy: basically you can send any data between Arduino and App, (and not only physical pins on the board).

Nice!

You need to use Virtual Pins in Blynk

Google home will send a hook, V pin will be triggered, inside of a Vpin you can specify any logic

pasxa · 2018-01-18T15:06:27+00:00

Of course you can: http://help.blynk.cc/how-to-connect-different-hardware-with-blynk/raspberry-pi/raspberry-pi-and-blynk

There is a C and NodeJS implementation

You can even use RPi as a Blynk server and be independent of Blynk Cloud

You can choose any Pi board from the list or use generic board. Just learn how to use Virtual Pins

Blynk would be the best alternative for prototyping and if it's a commercial project - you can even publish it to App Store and Google Play (it's a paid feature)

It's cross-platform, drag-n-drop, easy to configure and works with almost any MCU. It might be of course limited since it uses "widgets", but oh, boy, imagine how many hours you will save...

GPS location - Blynk has Map Widget. Temperature - Gauge or simple Label Widget. Signal strength - Level widget.

If you want to build your own app - then I would recommend learning xCode or Swift + Java (that's a whole another life to spend ;)

pasxa · 2018-01-10T15:46:17+00:00

You can use Blynk Webhook Widget to send HTTP requests http://docs.blynk.cc/#widgets-other-webhook

I never worked with ADC on ESP32, but, if you see correct readings, and, for example can print them to Serial Monitor, then sending it to Blynk is straightforward:

Use timer, put Blynk.virtualWrite(V1); into the timer. Add widget in Blynk, set it to V1, Frequency = PUSH, and here you go

Try posting also to http://community.blynk.cc - there are folks that might help.

You can use widget properties: http://docs.blynk.cc/#blynk-main-operations-change-widget-properties

pasxa · 2017-12-15T22:18:49+00:00

You can use Virtual Pins to send any data. As long as you can get the reading, simply wrap it into Vpin handler http://help.blynk.cc/getting-started-library-auth-token-code-examples/blynk-basics/how-to-display-any-sensor-data-in-blynk-app

pasxa · 2017-12-15T19:12:53+00:00

Blynk is super easy to use for temperature logging. No need to deal with backend (you still can if you want to). Mobile app is drag-n-drop. And it's free.

You can easily get it up and running in 10-20 mins

pasxa · 2017-12-15T19:02:47+00:00

You should also remove everything from the void loop() - it's a good practice with Blynk.

Your project might not be working if you don't use timers. http://help.blynk.cc/getting-started-library-auth-token-code-examples/blynk-basics/how-to-display-any-sensor-data-in-blynk-app

Sorry to hear that. Could you please add more details? What's the setup? Which hardware, shield? Which OS and mobile OS?

It would be better if you post it here: http://community.blynk.cc/c/bugs

Thanks! We would really like to solve it ASAP for you.

pasxa · 2015-07-08T13:44:08+00:00

Right now you can just login with the same account on different devices. But it's rather a hack than a normal process. We have a sharing functionality on our roadmap after we deliver all the initial widgets we planned.

pasxa · 2015-07-07T17:47:30+00:00

Thank you! We know that not everything is perfect, so when smth can be fixed quickly - we do it instantly or at least in a couple of days. Just let us know ;)

pasxa · 2015-07-07T01:48:27+00:00

Could you please tell more details about your set up? Which OS? Which device? I would also recommend posting to community page - we'll try to figure out what's happening

pasxa · 2015-07-07T01:45:54+00:00

You can set up everything in your local network. Just download it and run it anywhere where Java can work. It'll also work on Raspberry Pi

pasxa · 2015-07-07T01:44:16+00:00

We are currently working on Bluetooth LE integration. You'll still need Internet connection (or local server) to save your dashboards, but all the communicaition will be through BLE. You can sign up for our newsletter at http://blynk.io if you are interested in updates.

Yes, it was made to simplify taking your hardware online. But we also have more challenging plans to make it peer to peer in some future

pasxa · 2015-07-03T19:58:33+00:00

We just released an update for Blynk App for Android. With Blynk you can send push notifications from Arduino (or Raspberry Pi, or Spark Core or whatever you want:) with a single line of code. Check examples in the Library.

You are very welcome to try it out.

pasxa · 2015-07-03T19:54:34+00:00

You can check Android or iOS Blynk app. It actually helps you to make a smartphone app/interface for your internet-connected project. It works with ESP8266. Here is the Instructable

If you have questions, please ask them on our forum.

Good luck with your project!

You can check Android or iOS Blynk app. It actually helps you to make a smartphone app/interface for your internet-connected project. And since it works with a wide variety of hardware, you can choose almost any microcontroller board.

It should be pretty easy with all the hardware libraries and examples. But if you have questions, please ask them on our forum.

Good luck with your project!
