Unknown error from ESP during install or update

ESPHome

Hello,

I have recently added 2 ESPHome devices,
but a lot of times during install or update they throw unspecified errors.

most of the times after an error the device gets unresponsive.
Now, for the first time the device keeps working.

Is there a way to find what is causing those errors, or prevent them from happening.

Try bringing it closer to the AP.

That’s not possible. Also it’s already pretty close.

Other possibility is perhaps the ota password is wrong.

Do you have the web server configured? If so you can upload new firmware in the web interface?

no that’s not it,
after this one I tried 2 times again, the 2nd one gave me a timeout, the 3rd try succeeded.
The issue here is that I sometimes need physical access to fix this,

which is not always easy.

I actually do use power_save_mode, but I think that shouldn’t be an issue, Tasmota by default applies this and with that one I never had any errors for the devices.
