Cycle Time is not the Intervall given in cfg it is 2s more for me.

Hello,

i use rscp2mqtt for a long time now and started to use PowerManagement ("e3dc/set/power_mode":) to load/idle the Battery with an dynamic tarif.

To load the Battery for an Hour on low charges, i use charge:12000:1800 on an interval set on 2 seconds. i found that it loads nearly double the time (2h) than one hour.

Looking at the code i found, that you sleep in wsleep for the interval given. But the runtime of one cycle for me is nearly 1.6 seconds so one cycle is not 2 seconds but 3.6.

as a quick an dirty hack i changed wsleep to ` void wsleep(double seconds) {

while(seconds >= 0.0)
{
    mtx.lock();
    if (mqttRcvd || !go) {
        mtx.unlock();
        return;
    }
    mtx.unlock();
    if(seconds > 1.0) {
      sleep(1);
    }
    else {
      useconds_t usec = (useconds_t)(seconds * 1e6);
      if(usec > 0)
        usleep(usec);
    }
    seconds = seconds - 1.0;
}
return;

and measure the runtime within mainLoop at the start of the loop-body with ` struct timeval start, end;

while (go && !bStopExecution) {
    gettimeofday(&start, NULL);

` and at the end with:

` // Record end time

gettimeofday(&end, NULL);

// Calculate the time difference in microseconds

long seconds = end.tv_sec - start.tv_sec;

long microseconds = end.tv_usec - start.tv_usec;

double elapsed = seconds + microseconds * 1e-6;

//Calculate remaining wait

elapsed = (double) cfg.interval - elapsed;

if(elapsed < 0.0)

elapsed = 0.0;

wsleep(elapsed); `
