The `pca` switch {% term integration %} allows you to control the state of your [ELV PCA 301 smart switch](https://www.elv.de/funkschaltsteckdose-fuer-energiekostenmonitor-pca-301.html). You need an 868 MHz interface like the [JeeLink](https://www.digitalsmarties.net/products/jeelink) flashed with the [pca-hex firmware](https://github.com/mhop/fhem-mirror/blob/master/fhem/FHEM/firmware/JeeLink_PCA301.hex).

|
|
|
## Configuration
|
|
|
|
To use your PCA 301 switch or socket in your installation, add the following to your {% term "`configuration.yaml`" %} file.
|
|
{% include integrations/restart_ha_after_config_inclusion.md %}
|
|
|
|
```yaml
|
|
# Example configuration.yaml entry
|
|
elv:
|
|
device: SERIAL_PORT
|
|
```
|
|
|
|
This {% term integration %} will add all PCA 301 switches which are in range. You can read the total used energy in kWh and the current power in Watt.
