Can a SONOFF SNZB-02 Temp Sensor control SONOFF S31 Smart Plug through a Zigbee Bridge Pro Hub?

I’m trying to control a smart plug when the humidity drops too low. I assume these three would do that, but I don’t see how the humidity sensors control the smart plug or the smart plug sees the humidity sensor. Everything’s installed. Using eWeLink. Just don’t see how they control.
