When you flip "Home Assistant state changes" on while the other, mutually-exclusive "state changes (without attributes)" toggle is already on, the flow correctly rejects it (state_changes_exclusive error) — but then re-renders the form using the old stored config values instead of what you just submitted. Now fixed, to use the newly supplied values.
OTLP validation now sends a single real log record, clearly marked as a configuration validation message, instead of an empty payload
Some backends reject empty payloads (Loki with 422, Snowflake Observe with 400), and treating those codes as success also hid genuine problems such as a wrong encoding
400 and 422 responses are now reported as connection failures
The message text is shown in the OTLP setup, options and reauth forms
Diagnostic counter sensors (format errors, posting errors, events, postings) use the total_increasing state class instead of measurement
Warning: existing long-term statistics for these sensors were recorded as measurements (mean/min/max). After upgrading, Home Assistant may report a state class change under Developer Tools → Statistics; use Fix issue there to delete or keep the old statistics
Validation could fail with a 422 because of the empty payload when used with Loki, this status code is now taken to reflect remote service is available and authenticated
Automated testing and linting is done for both Python 3.13 ( with the corresponding 2026.2 max Home Assistant version) and Python 3.14 with the latest Home Assistant public release
Improved description of core changes and serializing JSON
Automation and script events generate title now only with entity_id for clarity and consistency with other events
Tidied up ConfigFlow UI for Home Assistant standard events
Defined message titles for all the device/entity/label/floor etc registries
system_log_event is usually suppressed as an event name, since its noisy in a purely logging context. It can now optionally be emitted like any other event name, helpful if remote_logger being used more as a HA event store
