[Bug]: With KVV I only get 1-3 (max) entries

[fft1010]

The problem

Hi,
the versions before (all that I used and tested) had 5-8(?) departures as a minimum. With the new version I only see 2 if lucky I had three. With IRIS-TTS I see the 8 I wanted to see. The IRIS-TTS Sensor is way longer than the KVV sensor

See here KVV sensor:

Hi @fft1010, thanks for opening this issue! 👋

⚠️ Bug Report Received

To help us solve this faster, please check:

• Have you provided your configuration.yaml or integration config?
• Did you enable debug logging (custom_components.db_infoscreen: debug) and include logs?
• Is your Home Assistant version up to date?

A maintainer will investigate shortly.

Thanks for confirming this as a bug 👍

I can confirm the root cause is the size check happening before route/prev_route/next_route cleanup.

Below is the exact fix I applied locally, which restores the 2025.x behavior (multiple departures shown for VRR/EFA stations).

---

Current problematic logic (simplified)

MAX_SIZE_BYTES = 16000

temp_list = filtered_departures + [temp_departure]
json_size = len(json.dumps(temp_list))

if json_size > MAX_SIZE_BYTES:
    break

This check runs before cleanup of large fields such as:

• next_route
• prev_route
• route
• via

As a result, a single VRR/EFA departure can already exceed the size limit, causing all departures to be filtered out.

---

Proposed fix

Move the size check after cleanup, just before appending the departure:

# after route/via/prev_route/next_route cleanup

temp_list = filtered_departures + [departure]
json_size = len(json.dumps(temp_list, default=simple_serializer))

if json_size > MAX_SIZE_BYTES:
    _LOGGER.info(
        "Filtered departures JSON size would exceed limit: %d bytes (limit %d) for entry: %s. Stopping here.",
        json_size,
        MAX_SIZE_BYTES,
        self.station,
    )
    break

filtered_departures.append(departure)

Alternatively, increasing MAX_SIZE_BYTES (e.g. to 120000) also resolves the issue, but moving the check after cleanup keeps the limit meaningful and consistent.

Happy to test a PR or beta fix if needed.

[FaserF]

Can be tested now in the latest beta release :)

Hi,
awesome. KVV now works perfectly for me. Many thanks! Duplicate remove is great!

all the best
Juergen

[DerLagul]

Tested the latest beta (2026.2.1b0) — thanks! 🎉
The original issue (only 1 departure / filtered out due to size limit) is fixed on my side and I’m getting the expected number of departures again.

However, I’m now seeing intermittent connection timeouts for my station (Duisburg, Im Schlenk).

Home Assistant also occasionally creates a Repair entry (API error for station). The integration still works overall — it’s mainly the repeated Repair/notification warnings that are a bit noisy.

Home Assistant shows:

Connection timeout

Example log entry:

Timeout fetching data from https://dbf.finalrewind.org/Duisburg,%20Im%20Schlenk.json?platforms=1%2C2&efa=VRR2

My update interval is currently set to 5 minutes.

This looks more like a backend/API or rate-limit issue (dbf.finalrewind) rather than a regression from the size-limit fix — but I wanted to report it here in case the beta changed request behavior.

Happy to test further or provide additional logs if needed 👍

[FaserF]

Improved with the latest changes. I will drop a stable release now, but happy to hear your feedback still, if anything is not working as expected with the latest changes

[FaserF]

Another fix for the timeouts has been now released in the stable release channel.

#105

There are some new api rate limits from dbf: https://faserf.github.io/ha-db_infoscreen/limitations/#api-rate-limits

[fft1010]

api call timeout is gone woth 2026.2.2
IMHO this can be closed.
