the strange think is if i wait a few seconds this goes on with normality.

@koen01
what have you done to this not happen?

maluko

if i delete all mysensor code it work fine, but i want to send at my domoticz server.

thanks

hi,

since month that i wondering if could built a controller for the water floor heater system,
i have solar panel with a pump that bring warm water to circulate on floor pipes.

so my goal was built the controller for this, I started with small code after I added more features and ended up creating a board with components.

very soon , it is a temperature comparator with LCD , a button to temporarily turn on the LCD and the other to change the summer / winter cycle.

But when i arrived at finish part i discover a bug, that is when there is a rapid power failure the system does not restart , it is with the LCD turned on but not the system works.
just as I am a curious coder , having not been able to solve the problem, i am asking for your help in such problem.

Thanks

i have update with my sample, i think that will run ok.

#include <MySensor.h>
#include <SPI.h>          //import  MySensors library

#define trigPin 6
#define echoPin 5
int max = 91; //distance (cm) from min water level to sensor 
int min = 6;  // distance (cm) from max water level to sensor
int procent; //distance percentage
int ilosc; //amount of the tank as a percentage

#define child_id_ilosc 1   //setting to identify the amount of water in the tank

MySensor gw;
MyMessage msgilosc(child_id_ilosc, V_IMPEDANCE); 
 
void setup() {
  
  pinMode(trigPin, OUTPUT); //Pin, that its connet to trig
  pinMode(echoPin, INPUT); //a echo, input
 
  gw.begin();   //launch MySensors library  
  gw.sendSketchInfo("Water tank meter", "1.0");
  
  gw.present(child_id_ilosc, S_WEIGHT); //present data to controller
}
 
void loop() {
  
  long czas, dystans, diferenca;
 
  digitalWrite(trigPin, LOW);
  delayMicroseconds(2);
  digitalWrite(trigPin, HIGH);
  delayMicroseconds(10);
  digitalWrite(trigPin, LOW);
 
  czas = pulseIn(echoPin, HIGH);
  dystans = czas / 58;
  diferenca = max -min;
  
  procent = (((dystans - min)  * 100) / diferenca);
  ilosc = 100 - procent;
  
  gw.send(msgilosc.set(ilosc)); // send to controller

Hi people

i need a help with this project, have water solar heat for my floor and want to automate the pump, so i had a arduino skecht that can do with 1ºc difference and goes well but i want go further, want to see the 2 temp and the status of relay that act the pump.

my working controler are domoticz.
