My goal for this experminent was to lengthen the probe on the Ac Infinity cloudline fans. I have a T8 and A T6. Both are short about 4 foot of what I need. I also wanted to split the signal so that I only had to have one probe sending data split to two control units. Those of you that run two T model fans may find that one will read 73RH while the other reads 72RH for example even though they are right next to each other. I wanted to eliminate this.
I read reviews where people were not successful in lengthening the probe cable. I found that the probe cable used a 4 pole/conductor TRRS type meaning it has 3 bands/ insulators on jack. I found this cable

I tried using this https://www.amazon.com/gp/product/B01I37CIEW/ref=ppx_yo_dt_b_asin_title_o05_s01?ie=UTF8&psc=1 Y spliter to split the signal. It did not work. Only one jack can be plugged in at a time or both control modules lose signal.
I also tried this https://www.amazon.com/gp/product/B07D7W16Z1/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1 splitter hoping it might work. It does not. Same as the first. One line plugged in data goes to the control module. two lines plugged in neither module receives a readable signal…
So thats where I am at on this deal right now. It would be nice to only have one temp/Rh reading to deal with but not sure what the workaround is as of yet.
