Killswitch is independent of manufacturer and works with any EV charging station manufacturer or model:
For OCPP-compatible devices, the charger connects directly to Killswitch by using our OCPP server. For devices not supporting OCPP, you will need to use a Smart Switch from Shelly® so that Killswitch can control the power supply to the charger.
Yes - you can connect your charging station to Killswitch using OCPP (Open Charge Point Protocol).
Using OCPP is the most convenient and easy way to connect chargers to Killswitch, but our solution can also be used with non-OCPP compatible devices..
When using Killswitch with an OCPP-compatible device, you will be able to perform the following remote actions:
- Soft reset
- Request status notification
- Remote Start charge
- Remote stop charge
- Remote unlock connector

Killswitch currently supports it's interface in 5 languages: English, French, German, Spanish and Portuguese.
No - you can connect your charger to Killswitch using OCPP, meaning that no additional hardware is required.
If your charger does not support OCPP, then you may need to use Killswitch integrated with a small piece of hardware: a Shelly® smart switch that needs to be installed in the power line that feeds the EV charger. This smart switch will allow Killswitch to remotely control the power flow to the charging station. You can buy the smart switch directly from the Shelly® website or from your local distributor. Supported smart switch models: Shelly® Pro 1 and Pro 1PM.
Yes, you will need to have an Internet connection for Killswitch to communicate with your EV Charger or smart switch.
OCPP devices are normally equipped with network connectivity options (eithet LAN, or WiFi or 4G) to be able to connect to an OCPP server.
If you are using Killswitch with a Shelly® smart switch, you will need to have a stable Wifi connection where the smart swicth will be installed (i.e. in the switch board) so that the smart switch can connect to the Internet.
No - you can easily configure Killswitch by yourself.
For OCPP Chargers, you simply need to enter the Killswitch OCPP server address in you device configuration.
For non-OCPP compatible chargers, you will need to install a Shelly® smart switch together with a contactor in the power line that feeds your charger. Despite the smart switch installation is rather simple, we recomend you to hire a qualified electrician to do so - to avoid shocks, equipment damage or other electrical hazards.
