Shelly 1PM can be driven by Shelly EM?

Hi. I want to use Shelly EM to monitor power in 2 points and turn on a 2000 Watt heater only if power is less than x. So far, so good. The problem is that Shelly EM shoud be connected to a contactor, and the contactor to heater. I wonder if I can connect the EM to a Shelly 1PM, and the PM to the heater. If so, any help about how to do it? Thanks

Obviously, I didn't got the point: I learned, the Shelly EM has an output to drive a contactor/external relay! Hence, controling the heater via Shelly EM and a relay is possible without a second Shelly device.

But feel free to correct me, if I should be wrong!

Thanks, but I need a second Shelly (1PM) to monitor if the heater is powered and operating or only powered but not operating

Scheme attached. I'd need to know if and how physically connect EM to PM. Thanks
