 - **A meter the panel reports without a breaker space** gets power, energy and current sensors, no switch, and its own place outside the breaker grid.
 - **Circuits that share a meter or relay name each other**, the panel view draws them as one slot, and current monitoring uses their combined rating.
-- **An EV charger lock** where the panel lets the charger be locked, and **busbar current, line frequency and upstream protection rating** sensors where the panel
-  publishes them.

 - **A battery the panel declares gets its device before its first reading**, reading unknown until then, and a battery fed by a circuit reports its connection.
 - **Registration says when to retry** if the panel limits attempts, and setup asks only for the passphrase where the panel does not support proximity.
 
 ### Changed
 
 - **Circuits with a solar role read and display as generation**, and solar fed through such a circuit gets a Solar device without a separate inverter device.
-- **A panel that publishes no solar source no longer gets a Solar device or PV Power sensor**; on an upgraded install those entities stay unavailable until removed.
-- **New installs no longer create the Status Postal Code and Status Time Zone sensors**; existing ones stay and keep updating, and diagnostics redact both values.

 - **The panel view draws only the breaker positions the panel has**, and shows a battery charge the panel has not reported as unknown rather than 0%.

-### Fixed
-
-- **An energy counter reading beyond what its breaker could ever carry is never used as the dip-compensation baseline**, so it cannot skew energy totals.
-- **The current-monitoring summary is hidden while monitoring is off**, instead of reading "0 circuits".
