It seems it doesn’t matter what I do or don’t do, and how I flash the board with either esphome-flasher or esp web, it all comes down to the same problem as I see it.
‘Can’t connect to ESP. Please make sure your YAML file contains an ‘api:’ line.’
Thank you. Those logs are what we have been after for a long time.
Your device is successfully connecting to wifi but is then boot looping (resetting and starting again).

You likely have a bad power supply, or you may have something connected to a boot-strapping pin. See: ESP32 Pinout Reference: Which GPIO pins should you use? | Random Nerd Tutorials

First , the pins that I am using for sda and scl are the ones I have always used when I first started 2 years ago, and there were no problems then. It only took me about 2 days to get it all up and running.
Also there are a few different esp32-wroom-32 boards, and to be honest it’s a bit of a minefield for me to make sure I do actually have the right pins. Again I am not sure if I should use GPIO21 in the yaml file or just 21 etc. I do have
i2c:
- id: i2c_bus
sda: 21
scl: 22
scan: false
The esp32 board was plugged into my laptop usb port, and I have also tried in my linux desktop usb port as well as a usb to 3 pin adaptor socket. They can’t all be bad, can they.
Since I last flashed the board with esphome-flasher, the led now doesn’t blink / flash now, except when I reset it.
So is it a case of a bad board.
Thanks
“Bad power supply” could also mean the 3.3v LDO (low drop-out) voltage regulator on the board. Or bad filter caps. The cheap Chinese clones are notorious for this. See this topic for some recommendations of good boards: What's your favourite ESP32 board? (# Best, good, cheap, quality, reliable)
As long as you have the board definition correct it does not matter if you use 21 or GPIO21.
I measured the voltage from the usb port a few days ago, and it was reading 5.08v to the esp32 board., but I take your point about LDO. Mine is an AZ Delivery ESP32-WROOM-32, and I’m loath to buy another of those so I have just bought these:
ESP32 ESP-32S Development Board 2.4 GHz Dual Core WLAN WiFi + Bluetooth 2-In-1 Microcontroller ESP-WROOM-32 Chip CP2102 for Arduino (3PCS)
These look like they are in the list of board , in the link you gave.
Thanks
If you have a fast voltage meter or a DSO measure the 3.3V voltage rail while it is running.
You can’t really say that until you disconnects your sensors and other stuff and see the behavior without those connected.
They could easily be bugged too.
I measured the voltage on the 3.3v rail while it was both in the usb port on laptop and in the usb mains adaptor, and it was fairly stable at 3.3v for a god few minutes. the led was not flashing tho’ so I do suspect the board is duff.
If you only measured it with a multimeter it won’t be fast enough to catch transients.
Well that is all I have. It’s an old Fluke 77 meter which I’ve had for a long time. Anyway my new board should be here tomorrow so we’ll see how that goes.
Just disconnect all extenal IO, and see what happens.
There could be something wrong in there, causing it to fail when initialized 
I removed the esp32 board from the breadboard I had it on, and flashed it again with same file as I used earlier, but it made no difference.
All I had was the esp32 at the end of a usb lead.
So it still boot loops with no (external) hardware attached?
Showing this in the logs again?
To rule out (or confirm) a hardware defect you can create a minimal yaml file with only the basics and flash this to the esp to see if it comes up normal or continues to boot loop (which will be a good indication that it is a hardware fault).
A minimal yaml can look like this:
esphome:
name: minota
platform: ESP32
board: esp32dev
wifi:
networks:
- ssid: 'YOURSSIDHERE'
password: 'YOURPASSWORDHERE'
ota:
logger:
As a site node there is no api: line in that yaml so you can’t connect it to HA that way. It is just to see if a minimal firmware is able to run stable or if that also causes boot loops 
Thanks but how would I know if it is either sable or causes boot loops
Log. You posted above
Yes it does seem to be going in boot loops:
[19:06:19][I][logger:258]: Log initialized
[19:06:19][C][ota:469]: There have been 1 suspected unsuccessful boot attempts.

And then
[19:11:19][I][ota:113]: Boot seems successful, resetting boot loop counter.
That’s great news! Looks like no more boot loops. Otherwise you would see such a message in a regular interval:
As for it didn’t confirm the thesis of a hardware fault.
You should be good now to flash/install the full yaml once again (maybe you also want to share that one in your next post) to see if it behaves any better now.
Try the OTA (Wireless) install method in the esphome dashboard as that should work now 
No, sorry, I am still getting the same error about not been able to connect and make sure there is an API line in the file, when I try to configure the existing esphome integration.
I hope to get my new esp32 board tomorrow so we’ll see how that goes.
