stevehoyt Posted February 22, 2011 Share Posted February 22, 2011 I have added 2 additional Venstar thermostats today one went in correctly and without an issue. The second hangs about 75% into adding the device with the green writing icon on the thermostat. I get the error Socket open failed java.io.IO Exeception An existing connection was forcibly closed by remote host. It hangs the admin console and I have to reboot the ISY to continue. Do I have a bad dongle or any ideas what to do? I have model 2441V version V.91 The thermostats both are 2491T1 T1700 with the humidity sensor not soldered out yet. I am at version 2.8.16.

Michel Kohanim Posted February 23, 2011 Share Posted February 23, 2011 Hello stevehoyt, What is happening is that ISY cannot communicate with the thermostat ... is it possible to do a swap? i.e. plug the good dongle to the bad thermostat and vice versa. If the problem moves with the dongle, then you have a defective dongle. If the good dongle stops communicating with ISY, then the problem is that the signal is not reaching your thermostat. With kind regards, Michel Link to comment
