How to set OTA password
Since release v4.1.0, the OTA component is in a separate (external) package, so it is no longer in your config when you adopt the Home Assistant Glow in ESPHome dashboard. Fortunately, the ESPHome platform has an ID under the OTA component so you can use !extend. This way, you can set the OTA password in your Glow configuration.
your_glow_config.yaml
ota:
- id: !extend ota_esphome
password: "your_password"
In the example above, replace your_password with the password you want to use for OTA updates. Of course, this way you can not only add a password, but also override all platform options with your own settings.
