# Gas Water Heater

## Features

- Supports target temperature

## Customize

- Set the temperature precision for whole or halves (false for whole and true for halves, default by false)

  If the temperature value displayed on your water heater is twice the actual value, please set this value to true.

```json
{ "precision_halves": true }
```

- Set the temperature step (1 by default).

```json
{ "temperature_step": 0.5 }
```
