Giving a value of 0 by default can lead to erroneous data being exported. For example, if a MQTT temperature sensor is in `STATE_UNKNOWN` (which can happen after a HASS restart), a temperature of 0°C will be exported. Some user might prefer no value rather than a wrong one. |

Prometheus integration
This integration exposes metrics in a Prometheus compatible format.
Metric naming guidelines
Please follow these guidelines while defining metrics.
- Metric and label names should conform to Prometheus naming guidelines.
- Domain-specific metrics should have the domain (
sensor,switch,climate, etc.) as a metric name prefix. - Enum-like values (e.g. entity state or current mode) should be exported using a "boolean" metric (values of 0 or 1) broken down by state/mode (as a metric label).
