Pull request overview

This PR removes outdated and invalid password hashing instructions from the JVC Projector integration documentation. The instructions were for NZ800 and NZ900 models but are no longer needed since the underlying issue was fixed in a previous core PR (#126453). The removal improves documentation accuracy by eliminating instructions that would mislead users.

Key changes:

• Removed the entire "Password hashing for newer models (NZ800 and NZ900)" subsection containing outdated workaround instructions

Comments suppressed due to low confidence (1)

source/_integrations/jvc_projector.markdown:44

• The removed instructions previously directed users to paste their projector password (concatenated with JVCKWPJ) into a third-party online SHA256 hash generator, which leaks the password material to an external service. An attacker controlling or eavesdropping on that service could capture these secrets and reuse them to control the projector or any other system where the same password is used. Removing this guidance avoids encouraging users to transmit passwords to untrusted websites; if hashing instructions are needed in the future, they should rely on local tools or built-in functionality that never sends secrets off-device.

## Remote

The JVC Projector remote platform will create a [Remote](/integrations/remote/) entity for the device. This entity allows you to send the following commands via the [remote.send_command](/integrations/remote/) action.

- `menu`
- `up`
- `down`
