Blynk Alert

then I have to learn programming! So that I can do it.
I only tested single skits. How to make the buzzer sound or how to turn an LED on or off via Blynk or how to make a wifi connection with the Nodemcu. But never tested a swimmer or found a useful code for it.

I assume that by “swimmer” you mean float switch?
As i explained before, it’s just a switch.

Stop looking for code and write your own to do the very basics, then build on that. You need to learn to walk before you can run.


OK thanks! then I will do it! because in 1 to 1 1/2 months before the finished aquarium controller is there I do not need this anymore because the entire programming already exists and then I only need to solder a lot and nothing has to be programmed just to set the complete software! yes I meant float switch!

Have you thought about something like this?

Not sure that the Blynk groupies will be happy :wink:


for my seawater controller I have a lot of modules and accessories including a nodemcu! I just wanted to make it with what I have and nothing to buy what I do not need anyway afterwards!
