Help with OTA encryption

ESPHome
1

Hi all,

I have a few ESP devices running and keep seeing warnings regarding memory use etc when updating regarding the use of encryption.

I can’t figure out how to enable it without risking locking myself out of the device?

Can someone help with a little guidance please?

Your best chance for help is to show your yaml snd the error/warning.

Of course, apologies for not doing so…

You comment out the password in the ota: section and add encryption: following platform.

ota:
  - platform: esphome
    encryption:
#    password: "xxxxxx"

PS: I assume you are using version 2026.9.0 or higher.
