Validation Error Binary_Sensor [Solved]

Operating environment/Installation (Hass.io/Docker/pip/etc.):

Hass.io on CentOS 7 with the latests stable release of addon ESPHome ESP (ESP32/ESP8266, Board/Sonoff):

esp8285 Affected component:

https://esphome.io/components/binary_sensor/index.html

Description of problem:

When i try to add the following to the YAML (switch): on_press: then:

switch.toggle: "${plug_name}_Relay" i get compliation errors, can't figure out why:

INFO Reading configuration... WARNING The esphomeyaml section has been renamed to esphome in 1.11.0. Please replace 'esphomeyaml:' in your configuration with 'esphome:'. INFO Detected timezone 'CET' with UTC offset 1 and daylight savings time from 03/31/19 02:00:00 to 10/27/19 03:00:00 Failed config

then: [source /config/esphome/energy_2.yaml:49]
- switch.toggle:
```

Traceback (if applicable):

Not possible to flash over USB, but seems not to be the problem because the validation already failed

Additional information and things you've tried:

Been adjusting the config, tried the direct name instead of the template but still won't validate.
