Tstat version numbers

[Jschaff]

I have two tstats. CT50 v.192 and CT50 v.194.

What is the difference between the two.
Also, could I be on the list to upgrade firmware if I am not already on the latest. Every so often one of them will revert to an earlier version

Thanks

There are minor differences in the thermostats operation but nothing to do with the radio. The Wi-Fi radio gets upgraded but the thermostat does not nor is it necessary. Others on this forum with connection issues have found whatever their issue, changing the thermostat does not fix those issues.
