Hi, I have an older (2009 vintage) operating Hunter PRO-C 300 (10 circuit max) sprinkler controller. My interest is to replace the control/display panel section of this controller with a DIY SIP installation to add wifi accessibility and more intelligent realtime weather adaptability. After a quick inspection of my Hunter system I'm wondering if it might be possible to utilize the valve driver section of this commercial controller combined with a near-standard SIP control system build. To determine if this idea has any merit I think I need to reverse engineer how Hunter controls their valve driver modules. The obvious place to do this is at the 11pin flat cable coming off the controller board and over to the valve drivers.
Since my system is still operational it limits how risky I can get with it doing the reverse engineering, so I thought I would ask whether anyone here has already done anything like this. My controller is a very low-end but quite common Hunter home system. From my visual inspection, it appears that the individual valve drivers may be operated directly from mpu i/o pins. Inspection of the 11pin flat cable signals during circuit operation should tell the tale.
