Which sonoff device to monitor and sync my computer and device on the next room

hello wanted to ask which sonoff can meet my needs, need a smart switch that would monitor/detect if my pc is on/off and sends/commands a 2nd Sonoff device wirelessly tp do the same on my watercooling PSU to turn it on or off located on the next room

wireless switch 1

detect if my computer (device 1) is powered on/off (trigger volt is either 3.3/5/12volts)

wireless switch 2 (relay)

turns on/off external watercooling setup (device 2) = options can turn on/off a 220v outlet to power on a PSU or can just simply connect a circuit (relay dry connection) like the pwr_on and GND on a atx PSU 24pin to start the PSU

prefered smart device that would run on 5volts

was looking at 2x RE5V1c but not sure if it can monitor a volt input as a trigger or if this would work

With a switch with power monitoring feature like SONOFF POW series and setup a scene to trigger another smart switch?

hello i bought the sonoff s31 and the iplug s40TPB both have power monitoring but thier is no triggers that would let me use it?

is it posible to use the power monitor info as if triggers?

but it’s not about the trigger,
it is about creating a Scene that will be based on the “Power >” parameter
“If S31 Power>100W than S40 ON”
