Some RT and ST variables are not ready and not synced!

[mr12obot]

After compile the project and debug messages via serial is worked until get all values and send updates to blynk.

But please find below the error messages looks like "Some RT and ST variables are not ready and not synced!"

Get all values.
Send updates to Blynk.
Some RT variables are not ready and not synced!
Some ST variables are not ready and not synced!
Starting timed actions...   
SETUP OK!

Then after check via blynk app doesnt appear for this vPIN (min_batt_voltage, max_batt_voltage, charge_status, discharge_status, energy_generated_today/month/year/total)

How to fix this error issue?

[Bettapro]

Some RT variables are not ready and not synced!
Some ST variables are not ready and not synced!

We have some communication issue between esp/solar charge controller, normally, caused by bad wiring or bad solar charge controller not willing so send us the data requested (sometime it happens to me too once in a while, but it solves on its own in few minutes)

Are all other values synced correctly?

First step, I would check the Serial monitor after esp has booted (after "SETUP OK!"), every update request from the controller will generate a message "Update Solar-Tracer SUCCESS!" or "Update Solar-Tracer FAILED!". Do you have mixed messages? (some fails some success) Could you wait few secs after boot (10/15sec should be ok) and attach all the serial messages?

(If you're using my blynk project template) you can try with the button "sync all" in settings, it triggers a complete update of all values, so, it could solve.

[mr12obot]

After "setup OK!" every update request looks working. The controller generate "Update Solar-Tracer SUCCESS!".

Then I have no mixed messages or some failed messages. Already wait few secs still doesnt appear for those vPIN mentioned before.

Please find below the capture serial messages.

In these case: warning messages you got on the startup about the variables not ready and synced are caused by the esp issuing lots of requests to the charge controller (this time in your log al RT variables are synced at boot, only st are not synced). Should be interesting to check the actual error code of those request...

Did you compile the firmware on just flash the precompiled one?

If you compiled it , check config.h and make sure the related vPins definition are uncommented (otherwise esp wont send any update to blynk about those variables)

..
#define vPIN_STAT_ENERGY_GENERATED_TODAY                V15
#define vPIN_STAT_ENERGY_GENERATED_THIS_MONTH           V16
#define vPIN_STAT_ENERGY_GENERATED_THIS_YEAR            V17
..
..
#define vPIN_MIN_BATTERY_VOLTAGE_TODAY                  V19
#define vPIN_MAX_BATTERY_VOLTAGE_TODAY                  V20
..
..
#define vPIN_CHARGING_EQUIPMENT_STATUS_TEXT             V24
#define vPIN_DISCHARGING_EQUIPMENT_STATUS_TEXT          V25
..

[mr12obot]

I've build and compile the project manually. so not used precompiled firmware.

Already check the vPins in config.h are uncommented all.

How do we check the actual error code of those request ?

[Bettapro]

Actually the modbus return code is managed internally from solar_controller class an it's not exposed. The only way is to make a temp. change just to have it printed on the serial monitor.

Open SolarTracerBlynk\src\solartracer\epever\EPEVERSolarTracer.cpp and search for void EPEVERSolarTracer::updateStats(), then add the Serial.println as below:

...
void EPEVERSolarTracer::updateStats()
{
  uint8_t result = this->node.readInputRegisters(MODBUS_ADDRESS_STAT_MAX_PV_VOLTAGE_TODAY, 29);

  Serial.println( result );

  rs485readSuccess = result == this->node.ku8MBSuccess;
  if (rs485readSuccess)
..

this function is called once at the boot, then every hour (more or less) but you can use "sync all" button to trigger it manually.

[mr12obot]

Since I already try to compare with epever solar station monitor software, the vpin have no issue and appear in their own software normally.

Will try with your suggestion to troubleshoot the return code. For sure will update to you soon after have result.

[Bettapro]

@mr12obot Check latest sources from the repository, now you will get some error codes, eg:

Update Solar-Tracer SUCCESS!
Update Solar-Tracer FAILED! [err=226]
Update Solar-Tracer SUCCESS!
Some RT variables are not ready and not synced!
Update Solar-Tracer SUCCESS!

Code 226 is a timeout error: no response from the solar controller (busy on other tasks or stuck on some tx/rx buffers..)

I've found one RT variable non synced, that was (probably) the cause for your Some RT variables are not ready and not synced! at boot. The variable non synced [vPIN_CHARGE_DEVICE_ENABLED] was disabled in my installation, I didn't find any gain to have it enabled (seems it's not doing anything!)

it should solve the issue anyway..

[mr12obot]

As per using the latest repository and try to use "sync all" button to trigger it manually, now all vPIN appear normally but still have issue only vPIN_MIN_BATTERY_VOLTAGE_TODAY and vPIN_MAX_BATTERY_VOLTAGE_TODAY not appear and still have messages below of some ST variables non synced. Please advice.

Could you attach a screenshot of how you set the widget in blynk app? ( these 2 widgets are not included in my template)

battery min/max. and generated energy today/week/month/year/total are requested all at once to the controller, so all of them should be empty.

[mr12obot]

please find a screenshoot below. i've just reset the generated energy and seems counting normally. but for the min and max battery not appear.

[Bettapro]

Checkout my latest code. I think I've disabled them on the controller side at some point, now you should have them updating correctly.

[mr12obot]

Already add latest code with your update below. but still have messages of some ST variables are not ready not synced and the min and max battery not appear.

Is there any step again to add ?

  this->setVariableEnabled(SolarTracerVariables::MAXIMUM_PV_VOLTAGE_TODAY);
  this->setVariableEnabled(SolarTracerVariables::MINIMUM_PV_VOLTAGE_TODAY);
  this->setVariableEnabled(SolarTracerVariables::MAXIMUM_BATTERY_VOLTAGE_TODAY);
  this->setVariableEnabled(SolarTracerVariables::MINIMUM_BATTERY_VOLTAGE_TODAY);

[Bettapro]

Checkout my latest code. Definetly it will solve, and you'll find some more features you'll like! ( #23 , #29)

[mr12obot]

Yes, finally the min and max battery voltage normally appear now.

And the feature debug messages over terminal widget works like charm. but still have messages of some ST variables are not ready not synced. how do we know and tracing which ST variables that have an issue at boot?

[Bettapro]

Please share your config.h .

You can also checkout latest code, there're some optimization that could help and more I've reviewed that warninig to report the numer of un-synced variables.

But, as far as all your data are updated and internal status is 0 (at least after a while) I woundn't be to much concerned.

[mr12obot]

As per checkout with the latest code, the number ST unsynced variables report now that have 6 ST Var. but still dont know which one.

The 6 vars are about energy generated and min/mav voltage during the day (exactly 6 as reported in the message).

I can see that those are working ok after the 2° refresh cycle, then it should be boot related, probably a timeout error generated by the solar charge controller due too much update requests.

Problems like this cannot be solved (if there's a solution actually) because:

1. epever is not providing any clue about this (manuals are not very documented on this topics)
2. communication errors could happen
3. it requires some kind of sniffing of the modbus packets to find something interesting (I don't have time to spend here at the moment)
4. this is not a bug in the code (communication is working fine), just something not behaving as expected, I already encontered some strange implementations here, I won't be surprised if this will added to the list 😆

As the esp should boot only once in a while this issue shouldn't cause too much troubles, I will create an issue for this specific issue and close this. Keep thing monitored and report if you find any issue.

[mr12obot]

Great explaination. Let us report if find any issue and monitored for the sync error on sync all while booting.
