Home Assistant 2026.4.2 changes how the JVC Projector integration handles picture mode and HDR processing by moving those options from the sensor domain to the select domain. This update fixes inconsistencies in state management, but it also breaks any automations, scripts, or dashboards that still reference the old sensor.jvc_projector_picture_mode or sensor.jvc_projector_hdr_processing entities. This guide walks you through a safe, step‑by‑step migration so your theater automations keep working after the 2026.4.2 upgrade.
As we move into the 2026-2027 ecosystem, Home Assistant is prioritizing actionable entities over passive sensors. In this guide, we will walk you through migrating your JVC Projector setup from the old sensor-based model to the new, robust select entities. We’ve spent hours testing these changes on the latest NZ and RS series firmware to ensure your transition is seamless.
What’s New for JVC Projectors in 2026.4?
The April 2026 Home Assistant 2026.4 release migrates JVC Projector picture mode and HDR processing from sensor entities to select entities because these are now treated as configurable settings rather than read‑only status values. This change aligns with Home Assistant’s pattern of using select entities for user‑changeable modes.
For years, JVC users relied on template switches or complex service calls to change picture modes. The core change is the shift from “Sensor” domains to “Select” domains.
Before 2026.4, picture mode and HDR processing were exposed as read‑only sensor entities, so you couldn’t change them directly from the UI. Changing modes required low‑level jvc_projector.send_command calls or custom templates. After 2026.4.2, those options are proper select entities, so you can change them directly from dashboards or automations usingselect.select_option, without remembering raw hex codes.
Now, the entity itself is interactive. You can control your projector directly from the UI or a single service call without needing to know the underlying API codes.
The Breaking Change: Why Your Automations Stopped Working
If your Home Assistant dashboards now show “Entity not found,” “Unavailable,” or “Error” for JVC picture mode or HDR processing, that’s expected behavior after the 2026.4.2 upgrade. The legacy sensor.jvc_projector_picture_mode and sensor.jvc_projector_hdr_processing entities are now deprecated and being replaced with select entities.
Home Assistant has officially issued a deprecation notice for several legacy entities. The most notable casualty is sensor.jvc_projector_picture_mode, which is now considered legacy and will be removed in future versions.
Common Symptoms of a Broken 2026.4 Migration:
- Dashboard cards showing “Entity not found” or a yellow exclamation mark.
- Automations that trigger based on picture mode changes failing to execute.
- Scripts or automations using jvc_projector.send_command may fail if they still reference the old picture mode commands, because the integration now expects those modes to be set via the new select entities instead.
The new standard introduces select.jvc_projector_picture_mode and select.jvc_projector_hdr_processing. These are not just replacements; they are upgrades that provide a predefined list of valid states supported by your specific JVC model.
Step-by-Step Migration Guide (The “Zero-Click” Solution)
We recommend following these steps in order to minimize theater downtime. Ensure you are running Home Assistant Core 2026.4.2 or higher before starting.
Step 1: Utilize the Repair Flow
Home Assistant’s built-in Repairs Dashboard is your best friend here. Navigate to Settings > System > Repairs. You should see a notification titled “JVC Projector Entity Migration Required.” Clicking this will show you exactly which automations and scripts are still referencing the old sensor entities.
Step 2: Updating YAML and UI Automations
Below is a concrete example of how your automations change after upgrading to 2026.4.2. The old pattern used the jvc_projector.send_command service with raw picture mode codes, while the new pattern uses the standardized select.select_option service on the generated select.jvc_projector_picture_mode entity.
You need to swap your service calls. Here is the before and after:
The Old (Broken) Way:
service: jvc_projector.send_command
data:
command: “pm01” # Hard to remember picture mode codes
The New (Standardized) Way:
service: select.select_option
target:
entity_id: select.jvc_projector_picture_mode
data:
option: “Frame Adapt HDR”
Step 3: Updating Your Dashboards
It is time to retire those old “Entity” cards. We suggest swapping to “Tile” cards. Because the new entities are in the select domain, the Tile card will automatically generate a dropdown menu on your tablet or phone, allowing one-tap switching between “Cinema,” “Film,” and “HDR10+” modes.
Step 4: Set the JVC Projector Network Password (2024+ Models)
Home Assistant 2026.4.2 requires a network password on 2024+ JVC models (NZ500, RS3200, and similar) before the integration can send Picture Mode and HDR Processing commands. If you skip this, the select entities will remain “Unavailable.”
To set the password:
- Open your JVC projector’s Web UI through its IP address in your browser.
- Navigate to the Network or External Control settings section and enable the network password option.
- Enter a strong password and save the settings.
- In Home Assistant, edit the JVC Projector integration (Settings → Devices & Services → JVC Projector → Configure) and enter the same password in the network password field.
After saving, the select.jvc_projector_picture_mode and select.jvc_projector_hdr_processing entities should reconnect and show available picture modes.
Information Gain: Beyond the Release Notes
While the official docs cover the basics, our team has uncovered a few “Information Gain” tips that will put you ahead of the curve:
- Native IR Support (2026.4 Feature): The new 2026.4 Infrared platform can now act as a failover. If your JVC projector enters a “Deep Standby” where the LAN card turns off, you can set a triggered automation to wake it via an IR blaster (like Broadlink or Global Caché) and then resume control via the Select entities once it’s online.
- Dynamic Dashboard Colors: Using the 2026.4 Section UI, you can now color-code your projector controls. We recommend a “Deep Amber” theme for the JVC controls to match the premium theater aesthetic.
- Voice Control with AI Assist: With the improved LLM integration in 2026.4, you no longer need rigid phrases. You can now say, “Hey Assist, make the projector look better for a dark room,” and if your alias is set correctly, it will trigger the select.select_option for “Cinema” or “THX.”
Troubleshooting Common Issues
“Entity Unavailable” after update: This is often caused by the JVC’s limited network stack. JVC projectors typically have a polling rate of about 2.3 seconds. If your automation sends three commands in one second, the integration will hang. Always add a 3-second delay between projector commands.
Network authentication errors (401 Unauthorized)
If you see “401 Unauthorized” messages in your Home Assistant logs when trying to control the JVC projector, the integration is likely sending the wrong network password. The JVC projector requires a user‑set password on its network port for 2024+ models.
To fix this:
- Open the JVC projector’s Web UI and confirm the External Control / Network password is set and enabled.
- In Home Assistant, open the JVC Projector integration configuration and ensure the password field matches the one on the projector.
- Save the configuration and wait a few seconds for the integration to reconnect.
For older NX‑series projectors that do not support a network password, leave the password field blank in Home Assistant.
“Entity Unavailable” after the 2026.4.2 update
If the JVC projector entities show “Unavailable” after the update, the most common causes are:
- The projector’s network IP or network password has changed and does not match the Home Assistant configuration.
- The projector’s network is unreachable from Home Assistant (e.g., wrong VLAN, firewall rules, or Wi‑Fi issues).
- High‑rate commands sent too quickly: JVC projectors often respond slowly to network commands; if your automation sends several commands in quick succession, the integration may time out.
To reduce timeouts, add a short delay (for example, 2–3 seconds) between projector‑related service calls in the same automation sequence.
Advanced tips: IR fallback and automation ideas
These suggestions extend your JVC Projector setup beyond the basic migration, but they are optional and not required for normal operation.

IR blaster as a fallback for unreliable TCP
Some JVC projectors can behave unpredictably when using TCP/IP commands, especially in standby. If your automation sometimes fails to turn the projector on or change the picture mode, you can use Home Assistant’s 2026.4 Infrared platform (for example, Broadlink or IR‑blaster hardware) as a fallback. Configure a simple “power on + input select” IR macro, and trigger it from an automation if the JVC projector’s network response times out.
Dashboard section styling for your theater
Home Assistant 2026.4 allows you to set background colors for dashboard sections. You can apply a dark theme color to the “Projector” or “Theater” section so your JVC controls visually stand out without affecting the rest of the dashboard.
Voice control with Assist
After migration, you can use Home Assistant’s Assist voice interface to trigger projector modes. For example, create an automation that responds to “Set the projector to Cinema” and uses the select.select_option service on select.jvc_projector_picture_mode. This is a usability improvement, not a core safety or health‑related feature.
Frequently Asked Questions – FAQs
Q 1: Why did sensor.jvc_projector_picture_mode disappear after 2026.4.2?
Because Home Assistant 2026.4.2 moved picture mode and HDR from sensor to select entities; the old sensor is now deprecated and removed if unused.
Q 2: How do I fix “Entity not found” for my JVC Projector cards?
Update the card’s entity_id from sensor.jvc_projector_… to select.jvc_projector_…, then remove any remaining legacy sensors from the entity registry.
Q 3: Why do I need a network password for 2024+ JVC models in Home Assistant?
2024+ JVC models require a network password for security; Home Assistant must match that password (or its SHA‑256 hash) in the JVC integration config to send commands.
Conclusion
Migrating your JVC Projector picture mode and HDR processing entities from the sensor domain to the select domain in Home Assistant 2026.4.2 improves state management and automation consistency. While breaking changes are always a bit of a headache, the result is a cleaner UI and much more robust automation logic. By following this guide, you’ve ensured your home theater remains at the cutting edge of the 2026 smart home landscape.
