H43 error at boot with Optional PCB emulation activated

[jllussa]

Hi, I have an Aquarea J + Buffer tank with Heishamon 3.0 + One Wire sensor attached since september 2022. I request values from HP/OneWire every 45 seconds.

Since day one, at boot, Aquarea throws error H43 "Z1WaterSensor problem". I overcomed this issue with Heishamon rule engine:

on System#Boot then @SetZ1WaterTemp = 36; @SetBufferTemp = 36; end

This works like a charm and Aquarea boots ok, but from time to time I think about solving this ¿"maybe bug"? directly in Heishamon source code.

Checking source code I see the function setupConditionals()

if (heishamonSettings.optionalPCB) { if (loadOptionalPCB(optionalPCBQuery, OPTIONALPCBQUERYSIZE)) { log_message(F("Succesfully loaded optional PCB data from saved flash!")); } else { log_message(F("Failed to load optional PCB data from flash!")); } delay(1500); //need 1.5 sec delay before sending first datagram send_optionalpcb_query(); //send one datagram already at start lastOptionalPCBRunTime = millis(); }

My guess is that it's failing to load the file optionalpcb.raw from saved flash and instead it sends the "default data"

byte optionalPCBQuery[] = {0xF1, 0x11, 0x01, 0x50, 0x00, 0x00, 0x40, 0xFF, 0xFF, 0xE5, 0xFF, 0xFF, 0x00, 0xFF, 0xEB, 0xFF, 0xFF, 0x00, 0x00};

As byte 8 is BufferTemp [FF] and byte 16 is Z1WaterTemp [FF] with BufferTank connected the error H43 triggers inmediately.

As function setupConditionals has some log message I'm trying to get those logs but I can't see them in webpage "Console output" nor toggling "MQTT LOG".

Can someone point me so I can get those "extra" logs?

Of course the final goal is to get Aquarea running from cold boot without using the rule engine tweak .

Like discussed on Slack , "Hardware log" (parallel connection to Heishamon with usb serial converter and laptop ) would help to see , what values are sent as first.

Well I have managed to get those logs as appointed by Mig-41.

Checking the code:

// Callback function that is called when a message has been pushed to one of your topics.
void mqtt_callback(char* topic, byte* payload, unsigned int length){
.
.
.
else if (strncmp(topic_command, mqtt_topic_commands, 8) == 0)  // check for optional pcb commands
    {
      char* topic_sendcommand = topic_command + 9; //strip the first 9 "commands/" from the topic to get what we need
      send_heatpump_command(topic_sendcommand, msg, send_command, log_message, heishamonSettings.optionalPCB);
    }

Optional_pcb.raw file is created only when heishamon receives an update of optional pcb MQTT topic!

So for the file to be created at least you have to send one time an update through MQTT topic. I have posted a message to commands/SetBufferTankTemp via MQTT client and booom, file created. If a user only updates optional pcb topics through CurlyMo internal rules engine (or with HTTP calls), this file will never be created nor updated.

Maybe this issue could be addressed in following versions. I will keep enjoying Heishamon PCB. Thanx !

To devs: I think using this piece of code, on commands.cpp, the "issue" would be gone. I don't have Arduino IDE to test and create a merge request so this is only a hint for the solution.

unsigned int set_xxx_temp(char *msg, char *log_msg, int byte, const char *func) {
  String set_pcb_string(msg);

  float temp = set_pcb_string.toFloat();

  {
    char tmp[256] = { 0 };
    snprintf_P(tmp, 255, PSTR("set optional pcb '%s' to temp %.2f (%02x)"), func, temp, temp2hex(temp));
    memcpy(log_msg, tmp, sizeof(tmp));
  }

  {
    optionalPCBQuery[byte] = temp2hex(temp);
  }

  if ((unsigned long)(millis() - lastOptionalPCBSave) > (1000 * OPTIONALPCBSAVETIME)) {  // only save each 5 minutes
    lastOptionalPCBSave = millis();
    if (saveOptionalPCB(optionalPCBQuery, OPTIONALPCBQUERYSIZE)) {
      log_message((char*)"Succesfully saved optional PCB data to flash!");
    } else {
      log_message((char*)"Failed to save optional PCB data to flash!");
    }
  }

  return sizeof(optionalPCBQuery);
}

I will check when I have time

Hi, I moved the save routine to the main loop so it saves every 5 minutes. Not depending on a new command (mqtt or rules). If you want you can try it after it finished building a test firmware: https://github.com/IgorYbema/HeishaMon/actions/runs/4285495143

Tested on build HeishaMon-alpha-44fe6c52988bf49845ee6653e10d54b7.bin All ok. Thanx!
