A simplehomenet tech helped me on the phone. I uninstalled Smarthome’s downloaded EZRain Configuration Utility. I installed the simplehomenetutilitysuite software in its stead. My Insteon system and the EZRain module works fine. I programmed a timer to turn Program 1 on later today. I will see if that works with my PLC from Smarthome. I understand that the EZBridge is a better option once Simplehomenet provides zone timers for its utility softward to control Insteon switchlincs in groups?
Now, so far, I am liking the EZRain sprinkler control. I will see later when my PC is off how well the timer works in the PLC-USB unit that also controls switchlinc timers.
