Remotec has discontinued their ugly IR Interface (ZXT-120) and replaced it with a much more attractive unit the ZXT-600.
The old device was known to Indigo as "IR Thermostat Bridge (ZXT-120)" but the new one, after inclusion just says "General Thermostat (v2)" and lists no configuration parameters in the status. However, I can access critical config parameters unique to the device and it looks nearly identical to the ZXT-120 (except config parameters look like they are 2 bytes now instead of 1).
I'm going to be setting up two of these as replacements for the ZXT-120 sometime in the next few days and will report if I have any problems. At first glance, it looks like they may work.
However, just to be sure, I am using the "Submit A Device" interface to send the status information directly to you so you can see if better support is easily possible.
Thank you.
