Nodemcu goes offline after a few minutes

When you say “changed the Auth code” do you mean that you re-created your project in the Blynk account that you set-up and are loved-in to that account on your phone and are using a corresponding Auth code for a device linked to that account in your sketch?

Yes i mean this i use now my own blynk account and this is working on the frankfurt server

@PeteKnight

Also, I strongly disagree with the notion that serial monitor baud rates above 9600 can cause reboots with this hardware.
In my opinion, you should always run the serial monitor at the native baud rate for the board you are using. In the case of the NodeMCU this will probably be 74880.

Ok then i change it to 74880

@PeteKnight

If the disconnections do not coincide with reboots then we need to start looking at other issues like WiFi signal strength etc.

My wifi distance to the node is maybe 4-5 meters think not thats the problem

@PeteKnight

If you are physically away from your hardware and MacBook during the week then maybe something like TeamViewer would be useful way of monitoring your serial output?

Yes thats a good idea then on saturday i leave a laptop on it that i can monitor with teamviewer

That should be perfect, but if the device isn’t rebooting each time the connection drops then the issue is most likely somewhere along the route between your device and your router, or the router to the Blynk server. Knowledge of whether or not a reboot occurs each time the connection is dropped, and if so what the reboot cause is would be extremely useful in narrowing-down the issue.

If your router is a cheap one that could be the problem. I have found from experience certain brands work better than others. In Canada I use a $150 Asus.

Its a speedport w724v

But other hardware works, i have a raspberry pi 3 with hassio and its never offline it works for months

So why aren’t you using Node-Red and the Blynk plug-in and controlling your NodeMCU via MQTT?
I personally never run Blynk code on my devices, they are all running MQTT with Node-Red acting as the ‘glue’ that provides the Blynk integration.

because i want the blynk interface, i.e. the app and the dashboard.

[PeteKnight]

Yes, that’s exactly what you get when you use the Blynk plug-in for Node-Red.

yes i tried it once i couldn’t get it to work so i looked for someone on freelancer. So I don’t know how, so to speak. So the add-on yes, but I did not get the mqtt to run. And how to connect it… i appreciate these devices and programs but unfortunately i just don’t have the time to “program” them so that they work together. set that, but not I call it connect.

Well, that approach didn’t work very well, did it?

The problem is that if you want to do customised home automation projects then you have to get your hands dirty at some point. The advantage of Node-Red is that it’s a drag and drop visual environment, which can make it easy to get started quickly - but it’s also very powerful and allows you to do more advanced stuff if you wish.

My home automation projects built with MQTT and Node Red

I thought I’d start a topic about some of the home automation things I’m doing with Blynk. We live in London, England, and also have a holiday home in Spain where we spend around 4 months of the year. Most of my home automation projects are based in the Spanish home and are aimed at simplifying day-to-day life while we’re there. My wife is disabled, and finds new technology a bit of a challenge, so all the projects that I’ve created are aimed at being practical, easy to use and reliable. Lets …

my home automation works it all works just integrating it into hassio blynk did not work i did not get the mqtt to work i did not know how to connect it to blynk
