HomeAssistant Core 2026.5.2 released on 15-05-2026
HomeAssistant Core 2026.5.2 is out now. It delivers a broad set of integration bug fixes and reliability improvements to reduce device flakiness and improve correctness across many platforms.
Check the HomeAssistant Core release notes on GitHub or the individual integration docs for full details and upgrade instructions.
What’s in this release
- Integration fixes to improve stability and correctness — examples include LG ThinQ ValueError handling for non‑numeric values, SmartThings only using switches where appropriate, Comelit unique_id fixes, ZBT‑1/ZBT‑2 migration to serial-number unique_id, Overkiz no longer marking devices unavailable incorrectly, homematicip_cloud setup and lock‑polarity fixes, Vodafone Station reinitialising API on stale sessions, Shelly media player availability, Alexa duplicate doorbell event fix, and cancelling previous Debouncer timers to avoid timing issues.
- MQTT, serial and peripheral improvements — MQTT device discovery now honours shared QoS and encoding, segment/state handling fixed when new MQTT configs arrive, MQTT device subentry settings restored on reconfiguration, USB/serial tweaks (set serial port description from description rather than product) and serialx bumps, plus fixes affecting hassio backups, WebDAV timeout increased to 30s, and InfluxDB v1 reconfiguration corrected.
- Dependency and platform updates — multiple upstream bumps (afsapi, serialx, imgw‑pib, renault‑api, pyintesishome, pymiele, aioesphomeapi, aioharmony) and a frontend update. Note the Duco migration to python‑duco‑connectivity and related library updates.
Upgrade notes
- Duco migration to python-duco-connectivity is a breaking change: temperature sensors have been removed. See the Duco integration docs for migration guidance.
- If you encounter issues, restore from your backups or use your normal rollback process to return to the previous HomeAssistant Core release.
