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 Builder (add-on). 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.
