My ROAM works great too. I can even sit in my living room and turn on the sprinklers and my receiver port is in the garage also.
Awesome, good to know I'm not the only person that did this. Did you mount it right on the controller box? I carefully bored a hole into the side to fit the smart port and used a romex connector nut on the inside to hold it in place. I'll take a pic tonight. I just wish the remote had a feedback mechanism to tell me how much time is left on the current zone, instead of going into powersave mode. The only way I can tell that a zone is done running is when I hear the water stop running (I can faintly hear it running under my living room floor). I really have no reason to complain though....I just went from a noisy malfunctioning mechanical timer to a self-installed (with a lot of helpful advice from Wet_Boots) reasonably-priced remote controlled system. Out of curiousity, can a Hunter irrigation system be made to operate via a WiFi controller and software? I ask because I also just installed a Honeywell wifi thermostat (one zone, thermostat is located on 2nd floor) to control our central A/C. With the Honeywell Android app on our phones we can now control the temp setting from the couch or from hundreds of miles away.
I just wish the system would come on and go off quicker than what it does while using the ROAM, but I can easily live with what it is.
Mine doesn't have any major delay. When I start a zone I see it sending the signal and less than 5 seconds later my heads are popping out of the ground.
