Add the possibility to prefix entites with device name

[tekand]

It was removed in 4210d84.
The problem is that Home Assistant uses the name of the entity to generate it's entity_id and not the provided unique_id. This can result in identical entities in Home Assistant (if using auto discovery).

Or maybe an alternative to this would be to provide the value of unique_id in object_id as well. Reference: https://www.home-assistant.io/integrations/mqtt/#naming-of-mqtt-entities

Or maybe both? ;)

Prefixing name with device name is wrong. #381
https://developers.home-assistant.io/docs/core/entity#entity-naming

I think we need to provide unique_id.

People were requesting a prefix to distinguish between alarm panels: #329
Your pull request can be easily modified to cover that =)

I use HA as well, and have seen #381, but didn't find anything like that in my HA logs. Maybe I missed something.
Intead of unique_id you meant object_id, right? unique_id is already provided.

Regarding #329, it would only mean to remove 'Paradox' from it and leave only the serial, right? Or you prefer to have this configurable?

BTW are you still active on gitter? I have a problem with the target_state, that is a bit harder/longer to explain. :)

Sorry for confusion. I thought we do not provide unique_id. Then we should be all set. I do not think we need an object_id in addition.

Probably I am. Have not seen any notifications for a long time already.

Let's better have

f'{cfg.ENTITY_NAME_PREFIX}{self.entity_name}' if cfg.ENTITY_NAME_PREFIX else f'{self.entity_name}',

Default prefix can be "Paradox "

Usage:
MQTT_HOMEASSISTANT_ENTITY_PREFIX = '' - default

MQTT_HOMEASSISTANT_ENTITY_PREFIX = 'Paradox {serial_number} ' - will prefix with "Paradox abcdef"

Note the space in the end of prefix.

Can this be documented or included in pai.conf.example?

[yozik04]

It is there :)

Look for
MQTT_HOMEASSISTANT_ENTITY_PREFIX
