Sonoff NS Panel Boot Mode issue

[shaggie16 (MS)]

Hi all, new here so go easy on me. I am trying flash an NSPanel (not pro) to ESPHome. I cannot get it into boot mood. As soon as I ground the IO0 pin and reconnect the power, the panel fails to turn on. Without IO0 grounded, the panel boots up into eWelink as normal.
I have tried powering the panel using 3.3V from DSD FT232 adaptor, I have tried powering it from external 5V to the 5V pin on the board, I have tried powering it from the mains, I have used various sources for the ground including the built in ground pin, a second connection to the ground on the FT232 adaptor, ground from the mains panel etc.
Whatever I do, I get the same result - it boots fine in normal mode, as soon as I ground the IO0 pin the panel does nothing. Nothing on the screen and ESPHome Web cannot connect to it.

Any ideas? Many thanks

Try

1. Ground gpio0
2. Apply power
3. Release gpio0

It should then but in flash mode.

Is this the same issue?

Issue with flash Sonoff Nspanel

I’m trying to flash a nspanel with Esp home in HA. It is impossible to get the panel in boot mode. I have released the panel from the box. Doublechecked it is 3,3 V. The GIO pin in connected to ground. Addon ESPHome is downloaded to HA. Hmi.tft in wew folder. Bin.file downloaded to desktop. I belive everything is done correctly. When I try to flash there’s always an error message with unable to initialize… I have also tried to use ESP flash tool software to manually flash with the same result.…

Thank you for the reply. I had already read through that thread and some similarities but different cause it seems.

Thank you for your reply. Still not working. There is nothing in the screen when trying to boot into flash mode and I would expect to see a bootloader menu etc.
