MQTT Homeassistant Support for "datetime" and "date" Fields

[Xyaren]

Description

Similar to #1006
I would like to request Homeassistant MQTT Discovery support for date(times)s aswell.

[guillaumezin]

Hello, and happy new year.
Same here, for Domoticz, I can't figure out how to get date working, I'm having a really hard time understanding how parsing is supposed to work...

[john30]

someone wants to find out how date+datetime are represented in HA when exchanged via MQTT?

[Xyaren]

Currently I suggest using text (with a regex as done in #1006 / f0d737d ) as there is no dedicated date / datetime / time entity supported for mqtt discovery:

Currently supported entities:
https://www.home-assistant.io/integrations/mqtt/#mqtt-discovery:~:text=Entity%20integrations%20supported%20by%20MQTT%20discovery

Same problem: https://community.home-assistant.io/t/mqtt-discovery-input-datetime/444720

Feature request: https://community.home-assistant.io/t/mqtt-discovery-time-datetime/663870
(Please Vote for the feature request to make it visible)

[guillaumezin]

Text would be enough for Domoticz. But to be honest, I don't need this anymore, I'm using Hc1SFMode and Hc2SFMode to set holiday mode and it seems to work as expected

I add date and time in file "mqtt-hassio.cfg" on row 108 filter-name = ....|date|time|...

Change on rows from 148:

# HA integration: skip string/date/time types completely
type_map-string = string
type_map-date = date
type_map-time = time

Change on rows from 230:

type_switch-w-date =
    text,,,date = date,
    text,, = date,
    text,, =

type_switch-w-datetime =
    text,, = btime,
    text,, = dcfstate,
    text,, = datetime,
    text,, = bdate,
    text,, = 

type_switch-w-string =
    text,, = date,
    text,, = datetime,
    text,, = dcfstate,
    text,, = bdate,
    text,, = btime,
    text,, =

type_switch-date =
    sensor,, = date,
    sensor,, =

type_switch-datetime =
    sensor,, =

type_switch-string =
    sensor,, =

Change on rows from 330:

type_part-textdate = ,
  "command_topic":"%topic/set",
  "pattern": "^[0-3][0-9].[01][0-9].20[0-3][0-9]$"%state_class

type_part-textdatetime = ,
  "command_topic":"%topic/set"%state_class

type_part-text = ,
  "command_topic":"%topic/set"%state_class

Thanks for all the work on this, i still fail to understand how to declare anything in mqtt config file, but setting date is one of the most critical applications of ebusd im using.

[Xyaren]

I can confirm the changes are working :)
Be very careful with exposing the current date/time to homeassistant, as this will update VERY frequent and will pollute the history/recorder of your homeassistant instance.

I am planning to just use it for the holiday period, so that is not an issue.

I'll create a PR with the above changes.
With the default settings this should not have any impact for any user if we do not change filter-name right?
It would just allow editing of the dates for users having exposed any of the time/date/datetime properties themselves.

I use local config files for eBUS Deamon so I also lower priority of that values. In other case you also can skip recorder for that values at all:

exclude map (optional)
Configure which integrations should be excluded from recordings. (Configure Filter)

domains list (optional)
The list of domains to be excluded from recordings.

entity_globs list (optional)
Exclude all entities matching a listed pattern from recordings (e.g., sensor.weather_*).

entities list (optional)
The list of entity ids to be excluded from recordings.

event_types list (optional)
The list of event types to be excluded from recordings.

# Example filter to include specified domains and exclude specified entities
recorder:
  include:
    domains:
      - alarm_control_panel
      - light
    entity_globs:
      - binary_sensor.*_occupancy
  exclude:
    entities:
      - light.kitchen_light

I am aware of that, it's just something that you need to do explicitly.
Therefore exposing the property by default would be a bad idea.

thats what I think as well. would be better to just prepare it in the integration file and having to enable it explicitly imho (also valid for #1134)

[Xyaren]

That is exactly what #1134 does. It does not automatically expose the attributes, just makes them editable if they are exposed.

[chrizzzp]

I noticed even with the additions of #1134 in place, time entities with the datatype HTI are not automatically exposed to HA.

e.g.

r,,Time,time,,,,3500,,,HTI,,,current time
r,,z1QuickVetoEndTime,Quick Veto End Time Zone 1,,,,1E00,,,HTI,,,manual override end time for zone 1

Does it require a separate HA template definition?

e.g. _templates.csv:

time3,HTI,,,time

[Xyaren]

Any explanation on why the PR is not merged ?
