Implement serial mode for Nextion display HMI

Hi, Long time no see.　I have report about your evse-ciruit.
I just trying your evse for my car. But in your circuit something problem.
When I was supply with DC regulated power supply that direct current have 3A.
I make prototype 2 which diffrence in Diode and Capasitor. but the both have same direc current about 3A.
then when I check with oscilloscope Waveform is still triangle wave not sqaure triangle.
Was it intentionally made?　I little bit scarry for charging my real car when if that pcb and car are burn.

Hello, this project is amazing! I have tried multiple EVs, and it is working fine, but with a Skoda Plug-In, the car is throwing an error. The EVSE is at -9V State B.

I used an oscilloscope and the TL081CP is not reaching the low supply voltage. Instead of being at -12V it is at around -10.7V. Everything else looks fine, the rise and fall time is under 2us and the PWM frequency is at 1kHz. Maybe it is because of the TL081 not being a rail-to-rail OpAmp (it is a genuine one).

I have read the EN61851-1:2011 standard and the only value that is not within the tolerances is the negative voltage.

Any clue about what the problem may be?

Hello, I'm stuck in this state, Do you have any idea how to solve it?

Hello. Great project. But I have a problem to flash DevKIt from esp32s2-evse.bin. Everything seems to be ok, no error on flashing. But after I have such error in logs. Does it matter that my board is different from one on GitHub?

Hi, @dzurikmiroslav where I can find the web.cpio sources?

Hello I get this loop crash and de device can't boot.

Nice to meet you . My name is Adrian Zulnedi . Thanks to make it Evse ESP32 , I really Like it.
But I don't know how can I compliing in my ESP32. Cloud you tell me to get detalis Informations?
Because it's doesn't have information details. Thank you for your reading.

Hi Miroslav.
Some countries have two-tariff meters. The price of electricity at night is significantly lower than during the day. I really wanted to add a real-time charging scheduler (of course, the time must first be set via the NTP server). You did a wonderful job, thank you.

ADC calibration fails on chips without factory ADC calibration fuse burned. Those should be quite old chips.
logs:
I (840) adc: Calibration scheme version is Line Fitting
E (840) adc_cali: adc_cali_create_scheme_line_fitting(186): default vref didn't set
E (850) adc: No calibration scheme

From documentation on docs.espressif.com:
There is also a configuration adc_cali_line_fitting_config_t::default_vref. Normally this can be simply set to 0. Line Fitting scheme doesn’t rely on this value. However, if the Line Fitting scheme required eFuse bits are not burnt on your board, driver will rely on this value to do the calibration.

Nominal value is such case is - 1100mV. Adding this value to adc_cali_line_fitting_config_t cali_config solved the issue:

components/peripherals/src/adc.c

#if ADC_CALI_SCHEME_LINE_FITTING_SUPPORTED
    if (!calibrated) {
        ESP_LOGI(TAG, "Calibration scheme version is %s", "Line Fitting");
        adc_cali_line_fitting_config_t cali_config = {
            .unit_id = ADC_UNIT_1,
            .atten = ADC_ATTEN_DB_11,
            .bitwidth = ADC_BITWIDTH_DEFAULT,
            .default_vref = 1100,

Hello. Nice project!
Are you planning to support the OCPP protocol?
What about commercial use?

Hello!

I ran 'git pull' after last changes #de2fd29 and now i see the following:

I have the latest update of esp-idf v.5 and the rest I did not touch.

What to update to make it compiling?

Hello, I having problems when I use the ENERGY_METER_L1_CUR_ADC_CHANNEL=4 and PILOT_ADC_CHANNEL=1.
When I get consumption the Pilot return Error.. It's strange how different IO's can interfere with each other.
I'm using ESP32. Any Ideas?

Hello, you can explain the way how I can get PILOT_DOWN_TRESHOLD_X from a new board?
Thanks

Hello, I am working on one similar project, if you want we can't join energies and make a super evse based on ESP32 :).
Please let me know if you are interested.

Add Berry Script Language support for handling AUX inputs and outputs

Hi,
The configuration https://github.com/dzurikmiroslav/esp32-evse/blob/master/cfg/esp32devkitc/board.cfg says

#AUX
AUX_IN_1=y
AUX_IN_1_NAME=IN1
AUX_IN_1_GPIO=4

AUX_IN_2=y
AUX_IN_2_NAME=IN2
AUX_IN_2_GPIO=21

....

AUX_OUT_2=y
AUX_OUT_2_NAME=OUT1
AUX_OUT_2_GPIO=5

Вut in the electrical circuit https://oshwlab.com/dzurik.miroslav/esp32-devkit-evse these contacts GPIO=4,5,21 are not used.
These are optional functions, I think, but I want to clarify what role they play and how to correctly connect external connections to the board. I want to repeat the electrical circuit, first single-phase, then three-phase .... The software was reproduced, and everything works. Thank you.

Hello!

I tried to update from version 0.5.0 to 0.6.0 by air. I push the button (System::Firmware::Check for update) but nothing happened. I see red popup error "Cannot be fetch latest version info"

Error log is the following:
E (819032) esp-tls-mbedtls: mbedtls_ssl_handshake returned -0x2700
I (819032) esp-tls-mbedtls: Failed to verify peer certificate!

W (819042) httpd_txrx: httpd_resp_send_err: 500 Internal Server Error - Cannot be fetch latest version info
W (819042) httpd_uri: httpd_uri: uri handler execution failed

Also I noticed that I receive 404 for https://dzurikmiroslav.github.io/esp32-evse/firmware/

Or OTA feature is not working? Local update by bin file is working...

Hello!

I'm new in this field - ESP and so on.

I bought ESP32-S3-N8R2 thinking that there will be no problem compiling for this chip. But nothing good happened. Its compiling, but after flashing chip rebooting with error "system_internal.c:158 esp-idf".

I google that a lot of people have problems compiling on s3 or moving from s2 to s3.

I tried a lot on menuconfig \ github and esp-idf forums etc but no chance to make it working.

Is it better to buy S2 as you use or maybe you know some hints why its not compiling?

Regards

Hi everyone, thanks for project @dzurikmiroslav .
I have used only Arduino IDE before.
Now, i have eclipse with esp tools for this project.
I did examples project blink etc.
I open this project in eclipse and I couldn't do anything else.
thank you for your help

Also after #de2fd29 update I receive errors like below:

51 | ADC_ATTEN_DB_11 attribute((deprecated)) = ADC_ATTEN_DB_12, ///<This is deprecated, it behaves the same as ADC_ATTEN_DB_12

I need to change all to ADC_ATTEN_DB_12 in your code?
