Fixes an issue where HA 2024.5 stops the integration from receiving
updates unless devices are polled.

Improvements to existing devices

• many climate, water_heater devices: define temperature units #1855
• Yagusmart/Zemismart energy meter: make breaker id optional #1858

General improvements

• migration: use async_update_entry to avoid deprecation warnings #1854
• receive threads: schedule updates instead of calling async_ha_write_state directly #1869
