These are great

BUT they have two separate outputs for temp and humidity. I thought i was all set as it was cycling and keeping temp correct (humidity just naturally fell in line and wasnt tripping during daylight cycles)
i go look at my tent during dark cycle and the fan is off and 90% humidity! no bueno! fortunately it was early into flowering. turns out humidity controls a second output which had nothing on it (and my tent only has one exhaust fan anyway
if youre in a tent and want one exhaust fan to be controlled in those ranges you have to bridge the two relay outputs.
the easiest way to do this is to open up the dongle with the 2 AC output plugs. you'll see the blue and brown 110V AC outputs from the relay tied into the hot terminals of the receptacles. I cut a 1" piece of 16 stranded out of a scrap extension cord and soldered it between the two terminals (easy as they are already solder joints, just tin your wire and its not a big deal.
Be careful if you think your solder joints arent up to 10 AC circuit, maybe ask a buddy for help if youre uneasy. its a 5 min job . you could also do it without modding your unit by making a "Y" cord with two males and a single female socket where you tie the hots together in the female socket housing (you can do that "loop" wiring people sometimes do to wire receptacle sin series). this would makes the "mod" reversable and return the controller to dual output when the cable wasnt being used
