Add id to the ESPHome OTA block so package users can enable OTA encryption - #118

Conversation
Give the `platform: esphome` OTA entry in MSR-1.yaml and MSR-1_BLE.yaml
the id `ota_default` (same as MSR-2.yaml). Device configs that include
these files via `packages:` can then switch to encrypted OTA with
`!extend ota_default`, `password: !remove` and `encryption:`. ESPHome
rejects `password` together with `encryption`, and without an id the
packaged password cannot be removed.
No behavior change for existing users: the password and its
`${ota_password}` default are unchanged. Document the override in the
Core.yaml comment next to `ota_password`.

official ESPHome documentation OTA encryption password migration existing devices
💡 Result:
ESPHome’s current official migration guide says **don’t replace the OTA password with encryption in one step**. First update the device to firmware that offers encrypted OTA, while keeping the password in your config; then require encryption and remove the password. The procedure requires ESPHome **2026.9.0 or newer**. ([esphome.io](https://esphome.io/components/ota/esphome/?utm_source=openai))
- **With the native API:** Ensure the existing API encryption key is in your YAML—don’t generate a new key for a Home Assistant–provisioned device. Update with the password still configured, then add OTA `encryption:` and remove `password:` for the next update.
- **Without the native API:** The guide uses a temporary API block and key for the first update; then it moves that same key to OTA encryption and removes the password.
Check the device log for **“Encryption: offered, plaintext accepted”** after the first update and **“Encryption: required”** after the second. ([esphome.io](https://esphome.io/components/ota/esphome/?utm_source=openai))
The OTA docs also clarify that a password authenticates the uploader but does not encrypt the firmware in transit; OTA `password:` and `encryption:` cannot be configured together. ([esphome.io](https://esphome.io/components/ota/esphome/?utm_source=openai))

Document the staged OTA migration for existing devices.
This snippet can strand devices running the current password-based firmware. ESPHome requires an intermediate update before the device can require encrypted OTA. Limit this snippet to new devices or devices that already support encrypted OTA, and document the two-step migration. The migration requires ESPHome 2026.9.0 or newer, while these configurations currently allow 2026.8.0.

Version: 26.8.19.1 (no change, YAML-only; no firmware behavior change)
What does this implement/fix?
Adds
id: ota_defaultto theota: - platform: esphomeentry inMSR-1.yamlandMSR-1_BLE.yaml. This uses the same id asMSR-2.yaml. Nothing else changes: the password and its${ota_password}default stay the same, and so does the firmware.Why
Since ESPHome 2026.x, the native OTA can be encrypted with the device's API noise key:
ESPHome does not allow
passwordandencryptionin the same OTA block ('password' cannot be combined with 'encryption'). Same-port OTA blocks coming from packages are merged before this check runs.Because the MSR-1 OTA entry has a
passwordand noid, a device config that includesMSR-1.yamlthroughpackages:(the normal adopted-device flow) cannot switch to encryption:ota: - platform: esphomeblock withencryption:is merged into the packaged one, and the result has bothpasswordandencryption, so validation fails;ota: !removedrops the packaged block, but YAML does not allow the device file to declareota:a second time;id,!extendcannot target the entry.#81 made the password overridable (thank you!), but it cannot be removed, so the only way to get encrypted OTA today is to fork or vendor
MSR-1.yaml. #81 calls that a poor option because it breaks thepackage_import_urlflow.With an
id, a user who wants encrypted OTA can do it from their own device file:Users who change nothing keep the current behavior: the password is still
${ota_password}, which defaults toapolloautomation.Precedent: MSR-2
MSR-2.yamlhas had this id since July 2024 (98f065d), on bothmainandbeta:So MSR-2 users can already enable encrypted OTA from their device file with just:
I run exactly that on several MSR-2 units. This PR brings MSR-1 in line with MSR-2 and uses the same id name, so the override works the same way on both products. The only difference is the extra
password: !remove, because MSR-1 still ships with a default OTA password.Diff
The same one-line change applies to
Integrations/ESPHome/MSR-1_BLE.yaml.MSR-1_Factory.yamlis not changed: it already hasid: ota_esphomeand no password.(Optional, can drop if you prefer.) Extend the comment next to
