you are not dumb, I didn't know either till I bought one. You will have a wire coming from the accurite with a sensor on the end of it. Put the sensor inside the water wiggler. I will try to find a pic of it right now. You may not find the exact accurite but this will give you an idea, find one that shows temp and humidity and has a wire with a sensor on the end and it should work. Go get it and when you get back you come back here and I will find the set up pic for you.
