I remixed @Felix's model for the Bosch Standard Charger (4A) to accept a Sonoff S31 energy monitoring relay.

Built on @felix's model to simplify usage and enable me to create some automations.

I used a Sonoff S31 which enables me to monitor energy consumption and remotely turn the power on/off.  I use ESPHome (on the S31) and HomeAssistant to track power consumption, and automatically shut off the power to the charger when it completes charging.  I also use that to trigger a notification to my phone to unplug the bike.

I also simplified the wiring - uses everything “off the shelf” no creating your own outlet/cable.
