* Adds MoldIndicator sensor platform
This sensor may be used to get an indication for possible mold growth in rooms.
It calculates the humidity at a pre-calibrated indoor point (wall, window).
* Automatic conversion to Fahrenheit for mold_indicator
* Minor change to critical temp label
* Fixed docstrings and styles
* Minor changes to MoldIndicator implementation
* Added first (non-working) implementation for mold_indicator test
* Small style changes
* Minor improvements to mold_indicator
* Completed unit test for mold indicator
* Fix to moldindicator initialization
* Adds missing period. Now that really matters..
* Adds test for sensor_changed function
"unix" timestamp is number of seconds since Jan 1, 1970 UTC.
This allows scripts that use templates to generate time
deltas in seconds if desired from state attributes such
as last_updated.
Some examples:
timestamp now is
{{ as_timestamp(now) }}
timstamp of last change is
{{ as_timestamp(states.binary_sensor.garage_door.last_changed) }}
seconds since last change is
{{ as_timestamp(now) - as_timestamp(states.binary_sensor.garage_door.last_changed) }}
* Add STATE_UNAVAILABLE to states that are ignored when writing to the
database. This will avoid a field type error for string if the field
already contains a different type, eg integer.
* Add test for ignored states for influxdb.
* Clean up influxdb tests.
* Accept group without entities in configuration.
People seem to use these as placeholders for future expansion of their
home automation dreams, and we used to accept them. We still have to
specify at least one of 'name', 'view' or 'icon' so that the group is
parsed as a dictionary.
* Also accept empty entities: key in a group.
* Additional fix for empty entities value in a group config.
