EnCh - Entity Checker

EnCh is an AppDaemon app which can check Home Assistant entities and sends a notification if desired. EnCh also provides a Home Assistant sensor entity, showing the currently detected entities.

Supported Checks

• low battery levels of various devices
• proper entity state, e.g. not unknown or unavailable
• stale entites (not updated for a specified time)

Installation

• Python >=3.8 required!

Use HACS or download the ench directory from inside the apps directory here to your local apps directory, then add the configuration to enable the ench module.

App configuration

Here's an exemplary configuration for this app (to be added to AppDaemon's configuration file, typically apps.yaml). Adjust the values as you wish.

ench:
  module: ench
  class: EnCh
  notify: "notify.mobile_app_user"
  show_friendly_name: False
  exclude:
    - sensor.out_of_order
    - binary_sensor.always_unavailable
  battery:
    interval_min: 180
    min_level: 20
  unavailable:
    interval_min: 60
    notify: "notify.mobile_app_otheruser"
  stale:
    max_stale_min: 15
    entities:
      - binary_sensor.cube
      - sensor.humidity_stove
      - device_tracker.boatymcboatface

Configuration

General

key	optional	type	default	description
module	False	string	ench	The module name of the app.
class	False	string	EnCh	The name of the python class.
notify	True	string		The Home Assistant service used for notification
show_friendly_name	True	bool	True	Use friendly name in logs/notifications instead of entity id.
initial_delay_secs	True	int	120	Time to wait before first checks. This grace-period is necessary to give slow devices and integrations in Home Assistant a chance to become "available".
hass_sensor	True	string	sensor.ench_entities	Name of the sensor entity created in Home Assistant which provides the number of unavailable/stale/low-battery entities
exclude	True	list		Excluded entities. Supports wildcard/patterns via fnmatch
battery	True	map		Set to enable low battery check
unavailable	True	map		Set to enable unavailable state check
stale	True	map		Set to enable stale state/entity check

Battery configuration

key	optional	type	default	description
min_level	True	integer	20	Minimum battery level a entity should have
interval_min	True	integer	180	Minutes between checks
notify	True	string		The Home Assistant service used for notification (Takes precedence over the notify setting configured in General section)

Unavailable/unknown state configuration

key	optional	type	default	description
interval_min	True	integer	60	Minutes between checks
max_unavailable_min	True	integer	0	If an entity is unvailable longer than this time, a notification is triggered
notify	True	string		The Home Assistant service used for notification (Takes precedence over the notify setting configured in General section)

Stale entity/state configuration

key	optional	type	default	description
interval_min	True	integer	15	Minutes between checks (if this is longer than max_stale_min, we use that instead)
max_stale_min	True	integer	60	If an entity is not updated during this time, a notification is triggered
entities	True	List		If a list of entities is given, just these will be checked. Omitting this option checks all entities.
notify	True	string		The Home Assistant service used for notification (Takes precedence over the notify setting configured in General section)
