"""lvx-purge-orphans — remove deprecated HA-discovery entities from MQTT.
|
|||
|
|
|
|||
|
|
After the powermon-patches (g) cleanup + GS excl_filter additions:
|
|||
|
|
- several fields are no longer published (always-zero / dead on this hardware)
|
|||
|
|
- one entity got renamed (dc-ac_power_direction → dc_ac_power_direction)
|
|||
|
|
|
|||
|
|
This tool publishes empty retained payloads to those orphan config topics so
|
|||
|
|
HA forgets the entities cleanly.
|
|||
|
|
|
|||
|
|
Idempotent. Compatible with paho-mqtt 1.x and 2.x.
|
|||
|
|
|
|||
|
|
Usage:
|
|||
|
|
lvx-purge-orphans <broker> <user> <password> [--dry-run]
