Voltage controlled remote button

I have two remote controls that have off buttons and on buttons that control electrical outlet plugs. These outlets are not smart switches, only controlled via a remote. I want to make them controlled via Alexa.

I have another electric outlet that IS controlled via Alexa.

My thought was to put a low voltage DC power supply into the Alexa electric outlet. When power is detected in the DC power supply a circuit wired to the remote control would close the circuit for the remote control ON button. And then when power is NOT detected it would close the remote control OFF button. Make sense?

What would be a simple circuit to get this to work?

Thanks for any suggestions,
Topaz

I got the ON to work, by using a single pulse circuit wired to a relay switch. Now I'm stuck on the OFF. I was thinking of using another circuit, powered by a battery, that sends the OFF signal when it detects the ON power turning off. Not sure how to do this yet. Any ideas?

I did not understand the question very well.

But I have solved such situations:
- I measured the voltage with a digital voltmeter on the two contacts of the remote control "switch"
- I used an optocoupler CNY 17, but the transistor in this optocoupler has to be correctly polarized
- if it does not work in a sense you put it in the other sense
