Presence

appdaemon.plugins.hass.hassapi.Hass.get_trackers(self, **kwargs) → list

Returns a list of all device tracker names.

Parameters:

**kwargs (optional) – Zero or more keyword arguments.

Keyword Arguments:

  • person (boolean, optional) – If set to True, use person rather than device_tracker as the device type to query

  • namespace (str, optional) – Namespace to use for the call. See the section on namespaces for a detailed description. In most cases it is safe to ignore this parameter.

Examples

>>> trackers = self.get_trackers()
>>> for tracker in trackers:
>>>     do something
>>> people = self.get_trackers(person=True)
>>> for person in people:
>>>     do something
appdaemon.plugins.hass.hassapi.Hass.get_tracker_details(self, **kwargs) → list

Returns a list of all device trackers and their associated state.

Parameters:

**kwargs (optional) – Zero or more keyword arguments.

Keyword Arguments:

  • person (boolean, optional) – If set to True, use person rather than device_tracker as the device type to query

  • namespace (str, optional) – Namespace to use for the call. See the section on namespaces for a detailed description. In most cases it is safe to ignore this parameter.

Examples

>>> trackers = self.get_tracker_details()
>>> for tracker in trackers:
>>>     do something
appdaemon.plugins.hass.hassapi.Hass.get_tracker_state(self, entity_id, **kwargs) → str

Gets the state of a tracker.

Parameters:

  • entity_id (str) – Fully qualified entity id of the device tracker or person to query, e.g., device_tracker.andrew or person.andrew.

  • **kwargs (optional) – Zero or more keyword arguments.

Keyword Arguments:

namespace (str, optional) – Namespace to use for the call. See the section on namespaces for a detailed description. In most cases it is safe to ignore this parameter.

Returns:

The values returned depend in part on the configuration and type of device trackers in the system. Simpler tracker types like Locative or NMAP will return one of 2 states:

  • home

  • not_home

Some types of device tracker are in addition able to supply locations that have been configured as Geofences, in which case the name of that location can be returned.

Examples

>>> state = self.get_tracker_state("device_tracker.andrew")
>>>     self.log("state is {}".format(state))
>>> state = self.get_tracker_state("person.andrew")
>>>     self.log("state is {}".format(state))
appdaemon.plugins.hass.hassapi.Hass.anyone_home(self, **kwargs) → bool

Determines if the house/apartment is occupied.

A convenience function to determine if one or more person is home. Use this in preference to getting the state of group.all_devices() as it avoids a race condition when using state change callbacks for device trackers.

Parameters:

**kwargs (optional) – Zero or more keyword arguments.

Keyword Arguments:

  • person (boolean, optional) – If set to True, use person rather than device_tracker as the device type to query

  • namespace (str, optional) – Namespace to use for the call. See the section on namespaces for a detailed description. In most cases it is safe to ignore this parameter.

Returns:

Returns True if anyone is at home, False otherwise.

Examples

>>> if self.anyone_home():
>>>     do something
>>> if self.anyone_home(person=True):
>>>     do something
appdaemon.plugins.hass.hassapi.Hass.everyone_home(self, **kwargs) → bool

Determine if all family’s members at home.

A convenience function to determine if everyone is home. Use this in preference to getting the state of group.all_devices() as it avoids a race condition when using state change callbacks for device trackers.

Parameters:

**kwargs (optional) – Zero or more keyword arguments.

Keyword Arguments:

  • person (boolean, optional) – If set to True, use person rather than device_tracker as the device type to query

  • namespace (str, optional) – Namespace to use for the call. See the section on namespaces for a detailed description. In most cases it is safe to ignore this parameter.

Returns:

Returns True if everyone is at home, False otherwise.

Examples

>>> if self.everyone_home():
>>>    do something
>>> if self.everyone_home(person=True):
>>>    do something
appdaemon.plugins.hass.hassapi.Hass.noone_home(self, **kwargs) → bool

Determines if the house/apartment is empty.

A convenience function to determine if no people are at home. Use this in preference to getting the state of group.all_devices() as it avoids a race condition when using state change callbacks for device trackers.

Parameters:

**kwargs (optional) – Zero or more keyword arguments.

Keyword Arguments:

  • person (boolean, optional) – If set to True, use person rather than device_tracker as the device type to query

  • namespace (str, optional) – Namespace to use for the call. See the section on namespaces for a detailed description. In most cases it is safe to ignore this parameter.

Returns:

Returns True if no one is home, False otherwise.

Examples

>>> if self.noone_home():
>>>     do something
>>> if self.noone_home(person=True):
>>>     do something

Database

appdaemon.plugins.hass.hassapi.Hass.get_history(self, **kwargs) → list

Gets access to the HA Database. This is a convenience function that allows accessing the HA Database, so the history state of a device can be retrieved. It allows for a level of flexibility when retrieving the data, and returns it as a dictionary list. Caution must be taken when using this, as depending on the size of the database, it can take a long time to process.

Parameters:

**kwargs (optional) – Zero or more keyword arguments.

Keyword Arguments:

  • entity_id (str, optional) – Fully qualified id of the device to be querying, e.g., light.office_lamp or scene.downstairs_on This can be any entity_id in the database. If this is left empty, the state of all entities will be retrieved within the specified time. If both end_time and start_time explained below are declared, and entity_id is specified, the specified entity_id will be ignored and the history states of all entity_id in the database will be retrieved within the specified time.

  • days (int, optional) – The days from the present-day walking backwards that is required from the database.

  • start_time (optional) – The start time from when the data should be retrieved. This should be the furthest time backwards, like if we wanted to get data from now until two days ago. Your start time will be the last two days datetime. start_time time can be either a UTC aware time string like 2019-04-16 12:00:03+01:00 or a datetime.datetime object.

  • end_time (optional) – The end time from when the data should be retrieved. This should be the latest time like if we wanted to get data from now until two days ago. Your end time will be today’s datetime end_time time can be either a UTC aware time string like 2019-04-16 12:00:03+01:00 or a datetime.datetime object. It should be noted that it is not possible to declare only end_time. If only end_time is declared without start_time or days, it will revert to default to the latest history state. When end_time is specified, it is not possible to declare entity_id. If entity_id is specified, end_time will be ignored.

  • callback (callable, optional) – If wanting to access the database to get a large amount of data, using a direct call to this function will take a long time to run and lead to AD cancelling the task. To get around this, it is better to pass a function, which will be responsible of receiving the result from the database. The signature of this function follows that of a scheduler call.

  • namespace (str, optional) – Namespace to use for the call. See the section on namespaces for a detailed description. In most cases it is safe to ignore this parameter.

Returns:

An iterable list of entity_ids and their history state.

Examples

Get device state over the last 5 days.

>>> data = self.get_history(entity_id = "light.office_lamp", days = 5)

Get device state over the last 2 days and walk forward.

>>> import datetime
>>> from datetime import timedelta
>>> start_time = datetime.datetime.now() - timedelta(days = 2)
>>> data = self.get_history(entity_id = "light.office_lamp", start_time = start_time)

Get device state from yesterday and walk 5 days back.

>>> import datetime
>>> from datetime import timedelta
>>> end_time = datetime.datetime.now() - timedelta(days = 1)
>>> data = self.get_history(end_time = end_time, days = 5)
