Hi,

i am running EPSHome on my Home Assistant on Raspberry Pi 4.

The wireless installing of my ESP8266 always fails.

I tried several things, like a greater Swap File, but it has not worked.
Any help would be appreciated.

Show your yaml. Someone might be able to figure something.

You can try to uninstall ESPHome builder, and reinstall it again

This also
might help. Clean build files.

Paste the error into chatgpt and explain the context. Quite often it will give you a pretty good solution or things to test.

Or just tell you what you want to hear. I have had more bad luck using these things than good.

Chatgpt is always out of date. I don’t hold with it. For better accuracy I use I ching sticks.
‘Increasing, fruitful to have a direction to go.
Fruitful to cross the great river.’
I think that favours reinstalling esphome.

Can’t say that this is what I experienced, otherwise I would not have suggested it.
Do what you think you should do.

Thank you all for your answers, I tried all things and now I cannot uninstall ESPHome… I think the initial problem lies with ESPHome, when trying to uninstall it just throws an error.

I am currently reading other articles on the forum, to figure out how to uninstall all of ESPHome, before reinstalling.
