Please help!! I tore my tank down to change the sand and now can't get one of my Radions to connect to the Reeflink. I purchased both Radion XR15 pros Gen 4 brand new so I'm the only owner. I've tried a Factory reset via Connection Manager and ESL. Along with a firmware update. I've tried to add via USB, says is has imported successfully, but it doesn't show on the device list. I can control both MP 40's and the other Radion so I know Reeflink is working. Ecotech is conveniently open the same hours i'm working, so you Guys/Girls are my only hope.lol. Thanks again!
