**Reolink D340W - Homey Dashboard does not remember Sub Stream**

Hi,

I have a Reolink D340W (WiFi Doorbell) connected to Homey Pro using the official Reolink app.

I’m experiencing the following issue:

- The camera works fine in Homey on my PC.
- The camera works fine in the Homey mobile app.
- On my wall-mounted TCL Tab 10L Gen 4, I get a black screen when the dashboard uses **Camera (main - h264)**.
- If I manually switch to **Camera (sub - h264)**, the video works perfectly and remains stable.

The problem is that Homey Dashboard does not seem to remember this selection. Every time the dashboard is reloaded or the tablet is restarted, the camera tile reverts back to **Main Stream** , which results in a black screen. I then have to manually switch to **Sub Stream** again.

I have verified the following:

- Both streams use H.264.
- There are no network or authentication issues.
- Sub Stream works reliably over time.
- I cannot find any setting in either Homey or the Reolink app to make Sub Stream the default.

My questions are:

1. Is this a known limitation or bug in Homey Dashboard or the Reolink integration?
2. Is there a way to save Sub Stream as the default stream for a camera tile?
3. Can Homey Dashboard be forced to always use Sub Stream instead of Main Stream?
4. Has anyone with a Reolink D340W found a workaround for this issue?

Any suggestions would be greatly appreciated.

Thanks!

You might want to consider posting this on the main Reolink app thread, where this issue is being discussed with the app developer:

> Hi Koktail, There is a limitation I have found with this implementation of preferring H.264 over H.265 streams. Some cameras that have both streams H.264 still don’t work for the main stream (possibly due to the resolution and bandwidth limitations?). I believe it would likely be preferable to either change it, or add an additional setting, to set the preferred stream as the sub stream. Would this be possible please? Thank you kindly good sir saluting_face
