* Add version check in unit_of_measurement, to avoid error.
* Remove not needed metric check in unit_of_measurement.
* Add more value types to unit_of_measurement.
* Fix unit prefix
* Remove unused SCAN_INTERVAL variable.
Devices were not added without persistence enabled and restart of HA.
Node id was added to defaultdict(list) by mistake when checking if list
of defaultdict was empty.
* Fix adding devices in mysensors_callback.
* Change devices to regular dict.
Entity ids will now look like this:
sensor.philio_technology_corporation_psm021_slim_multisensor_doorwindow_sensor_7
sensor.philio_technology_corporation_psm021_slim_multisensor_luminance_7
sensor.philio_technology_corporation_psm021_slim_multisensor_motion_sensor_7
sensor.philio_technology_corporation_psm021_slim_multisensor_tamper_sensor_7
sensor.philio_technology_corporation_psm021_slim_multisensor_temperature_7
sensor.philio_technology_corporation_psm021_slim_multisensor_doorwindow_sensor_8
sensor.philio_technology_corporation_psm021_slim_multisensor_luminance_8
sensor.philio_technology_corporation_psm021_slim_multisensor_motion_sensor_8
sensor.philio_technology_corporation_psm021_slim_multisensor_tamper_sensor_8
sensor.philio_technology_corporation_psm021_slim_multisensor_temperature_8
And if there is several values of the same type in a node the instance id will be appended like this (three switches in the same device):
switch.fibaro_system_unknown_type0202_id1002_switch_9
switch.fibaro_system_unknown_type0202_id1002_switch_9_2
switch.fibaro_system_unknown_type0202_id1002_switch_9_3
Z-Wave have a unique node id, this is now added to the entity name.
This is a change will break old configs. The Z-Wave entity_id will have to be updated in configurations.
The reason for this change is that the old behavior created duplicate entity_ids if you have several similar devices. The order devices is included is not consistent so when the service was restarted the entity ids could change and the configuration for entities will be invalid.
There was also inconsistencies between the naming for sensors and switches.
