Please post the function node code separately so that people can more easily read and comment. Contributors often don't want to or don't have the time to load people's flows. Thanks.

thanks for replay i fix my flow by this

// This assumes msg.payload contains the array from the CSV
const schedule = msg.payload;

// Function to convert time string to minutes for comparison
function timeToMinutes(time) {
  const [hours, minutes] = time.split(':').map(Number);
  return hours * 60 + minutes;
}

// Function to check the schedule and send the setpoint
function checkScheduleAndSendSetpoint(schedule) {
  const now = new Date();
  const currentTimeInMinutes = now.getHours() * 60 + now.getMinutes();

  for (const item of schedule) {
    const startTime = timeToMinutes(item.time_start);
    const endTime = timeToMinutes(item.time_end);

    // Check if current time is within the start and end time
    if (currentTimeInMinutes >= startTime && currentTimeInMinutes < endTime && item.fonction_stab === "on") {
      // Send the setpoint value
      return { payload: item.setpoint };
    }
  }

  // If no schedule matches the current time, or fonction_stab is not "on", do not send anything
  return null;
}

// Run the function to check the schedule
const result = checkScheduleAndSendSetpoint(schedule);

// Check if result is not null, then send the payload
if (result !== null) {
  node.send(result);
} else {
  // Optionally handle the case where there is no matching schedule
  node.send({ payload: "No matching schedule or fonction_stab is off" });
}

You don't need the node.sends, simply return the result or object from the function node.

Also, you don't really need to mess about with hours and minutes calculations.

Since JS Date objects are actually millisecond representations, you can simply add/subtract them then divide by 60,000 to get minutes elapsed.
