Problem adding Venstar Thermostat

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.

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
