The problem
HI,
I added a new departure as a new device. I am using "Reitschulschlag" in Kalrsruhe, and use IRIS-TTS as data source. The URL looks like:
https://dbf.finalrewind.org/Hagsfeld%20Reitschulschlag,%20Karlsruhe.json?via=Jenaer
When created the first time, it works as expected.
I than wanted to try to remove possible duplicates, which "empties" the according sensor, and no data is displayed any more (there where departures)

As it was only a test, I just disabled the remove duplicates, but the sensor was still empty. (checking in developer tools for the sensor data.)
After deleting the device and starting again, the data was there immediately. I checked twice, so make sure it was not a problem of the finalrewind server.
What version of Home Assistant Core has the issue?
core 2026.1.3
What type of installation are you running?

What data source are you using (usually IRIS-TTS)?
IRIS-TTS
Example YAML snippet
From above Reitschulschlag pick the last IRIS-TTS.
I noticed the following when picking:
If you click on the 2nd IRIS-TTS the third is checked, if you than click again on the second the second is checked.
Anything in the logs that might be useful for us?
