Images of final assembly of these kits are great, especially if they show correct placement of the conductors and especially CTs, since that can be an issue.

Hi,

I have ordered a second car charger (my first works perfectly since 2y now !).

I have tried to mount and test it quickly because the construction of my garage is not finished ; just before the summer.

I have exactly the same issue : the screen still blank.

I have open an issue and the support has send me a new board (controller+screen).

I have replaced today, but, even if I have replaced both, the screen is on with elements but charge does not start... the car is well detected but charger energy still rest at 0 kWh...

i've tried to see if I have bad mount the wire or something like this but everythings seems to be OK.

Small clamp is on the neutral

Big clamp is on neutral+phase

Other problem is "i can't update the firmware v5.1 to v5.1.2. The percent range still block at 99% and don't update the card...

I have the car charger since 6 months now and i can't use it ...

For the first one, i have no trouble.

The odds of two sets of controller and display (original) and replacement having the exact same hardware issue is zero. There has to be something else going on, maybe a software bug. When you login to the station is the current readings 0A or is it just 0w on the display? Does the history show any data on Energy?

The process to enlarge the file partitions update to the latest firmware is:

The repartition process for the TFT LCD in the short term requires a USB => Serial adapter and esptools (requires Python and pyserial).

Download the 5.1.2 - openevse_wifi_tft_v1.bin, bootloader_16mb.bin and partitions_16mb.bin from

https://github.com/OpenEVSE/openevse_esp32_firmware/releases/tag/v5.1.2

Connect the module to the USB => Serial adapter, then put the module in bootloader mode by holding BOOT and then pressing RESET then release BOOT

Run the command:

esptool --baud 921600 --before default_reset --after hard_reset write_flash -z --flash_mode dio --flash_size=detect 0x1000 bootloader_16mb.bin 0x8000 partitions_16mb.bin 0x10000 openevse_wifi_tft_v1.bin

Nothing in history on my side (see attached)

Can you please send me an USB => Serial adapter that work great for that ? I can do that by the end of the week (after purchased adapter)

As asked here, could you explain how can we use the adapter on the screen card ?

There is no plug to pin it...

@ Benjamin.nicolle

This is the correct USB/Serial device to program the ESP32 WiFi. https://store.openevse.com/collections/all-products/products/usb-to-serial-comm

To program unplug the cable that goes between OpenEVSE and the WiFi/Display module and plug in the USB/Serial adapter. The extra Debug port is not usable for programming. The USB/Serial adapter from the OpenEVSE store comes with the correct wiring harness, a generic USB/Serial adapter should work fine if you build a harness.

As explained here for the "same" discussion, could you precise us where we need to connect the harness cables ?

.

Thanks for your feedback regarding the usb to serial adapter.
I see a lot of chip based : FT232RK, TFDI FT232RL, CP2102, CH340G etc

Any advice on the choice ?

I'll appreciate a feedback on the recommendation too because if we purchased yours on your store, it'll cost at least 35,9€ with delivery...

"To program unplug the cable that goes between OpenEVSE and the WiFi/Display module"

"plug in the USB/Serial adapter"

Press and hold the BOOT button then press RESET button. Release BOOT. This enters bootloader. Alternatively, you can hold BOOT while plugging in, then release.

The OpenEVSE adapter is a CP2102 with a custom harness to go from 0.1" dupont to JST PH.

Programming is standard for ESP32 chips.

The repartition process for the TFT LCD in the short term requires a USB => Serial adapter and esptools (requires Python and pyserial).

Download the 5.1.2 - openevse_wifi_tft_v1.bin, bootloader_16mb.bin and partitions_16mb.bin from

Thanks for the information ;).
