Esphome setting up the esp device

ESPHome
1

Hi Everyone, I am trying to get a relay working. I have an ESP32 wroom connected to a relay board.
I went through the esphome instructions there is no mention of how to set up the esp itself. Is there any info on this anywhere?

thanks

Did you see this?

no i didn’t see that, thank you very much.

thanks again brooksben11, that was a great guide, I feel like im so close to getting this working.

installed the add on esphome and then ended up at the web.esphome.io as there was “some wrong with my browser or something.”
clicked prepare for first use. I get installing and wheel turning for 2 minutes
configuration installed yay!!!
click close

details"esphome-web-41c9c4
software: esphome/2024.7.3"

next i select connect to wifi
enter wifi name and password

esphome-web-41c9c4
provisioning…
this fails…

I have a dongle that if i put its un and pw in it will work… but obviously this wont help me.

esp is an expessif esp32 wroom 32
there are a few different esp32’s to select when adding the esp, I am working my way through all of them so far all are the same result.
thanks

just use esp32dev

also, there are high changes to have wrong relay module/connections.
just post your module and wiring here…

Hi Karosm, thanks for the info,

thank you will do!
It’s just occurred to me that maybe its a 2.4 or 5.0 ghz wifi band issue.

awesome cheers, will do this when i get home, thanks again

Better to have separate ssid for different frequencies.

good idea, done.
The esp is now connected to the 2.4 I can ping it from my desktop which is on the other 5ghz band.

Seems you are right maybe a code error, as it still says offline and I cant get it to connect to the HA.

code if I press edit:
