Maxim,

We do not have a ready made solution to do exactly what you want at this time (for now you would need a computer to be running to implement this task). You could do this in a few ways:

1) Develop a microcontroller, raspberry pi, or Arduino type solution: This board that you develop could read our meters (using the RS485 protocol), it would parse the "Total Watts" from the RS485, if the "Total Watts" were above your set threshold, the microcontroller would shut off the relay to the external switch. This would take quite a bit of knowhow.

2) Same as above, but use the Omnimeter Pulse v.4: http://www.ekmmetering.com/ekm-metering ... pulse.html
With this the microcontroller would read the meter over RS485 and based on the "Total Watts" threshold, it could send a signal to the Omnimeter Pulse v.4 to turn one of the 2 relays inside the Omnimeter Pulse v.4 either ON or OFF. This would also control your load.

3) Use the EKM Push system -- We are working to incorporate the Omnimeter Pulse v.4 into the EKM Push system. With this you could have an unlimited number of Omnimeter Pulse v.4 meters spread around the world, and based off of the data coming into the Push system, you could control the relays remotely. This would be the most scalable system and would be the easiest to adjust the "Total Watts" threshold settings (or change to a different threshold like amps, volts, or kWh per day, etc).

Let me know if you would like me to provide more information on any of these options.
