Sprinkler Controller - Rain and Soil Sensors

First, YES I have read and reviewed the wyze document.
https://support.wyze.com/hc/en-us/articles/360052569471-Connecting-Soil-or-Rain-Sensors

What I am looking for is more info, which I am betting I am unlikely to get..

The S1 and S2 pins… what are they looking for to trigger ??

Rain Sensor output 24VAC to trigger it off? or Ground/Common to trigger off??

I am looking at using probably one of these 2 listed compatible devices for rain sensor

or

I personally sort of like the Orbit one better.. not really married to either, and BOTH are LISTED COMPATIBLE.

Can any one outline what the S1 and S2 terminals expect to use for rain and soil sensor interlock? NO or NC 24VAC ??? What??

From there I can take it to what I need. Seems the listed soil sensors are all disco’d.. but with the above I can find something to just send the NC or NO 24VAC signal.

Any ideas on this? ?

Thanks!

Any one used one of these for the soil???

Seems to provide a usable 24VAC contact source.. might have to power it own its own or beefier setup with some power distribution for it and the wyze.

Any one using it in S2 for soil and one of the above for S1 for rain???

Bueller?!?!
