Sonoff pow ring energy meter

My plan is as follows: I want to use the POW Ring energy meter to monitor a specific electrical line. The device will be powered by a separate, continuous power source. Using the ring sensor, it will measure the power in the monitored line. If there is power in this line, I want the POW Ring to turn on, and if there is no power, I want it to turn off. This way, I can also ensure that other devices operate in sync with the availability or unavailability of electricity in the monitored line.

Hey
It should work with a simple scene in the app.
