Please see below recommandation from customer for our YAML File

ota:
password: !secret ota_password
 to
 ota: platform: esphome
 password: !secret ota_password
Note the solution is the addition of the platform. Here is a further explanation: In esphome 2024.6 the ota configuration has changed, and it you have ota: in your yaml file it won’t compile without fixing. The old invocation was ota: password: secretstuff You now need to add platform, so it will look like this: ota: - password: secretstuff platform: esphome this will get you there. There is now also a platform: http_request as well, hence the need for a change. This is dealt with in the changelog ESPHome 2024.6.0 - 19th June 2024 — ESPHome.
