I hijacked a thread, So I am moving that separate discussion here.
In summary, for those using the new RTS thermostat sensors, You NEED the new GC2 panel running the new zwave version 4.55. GC3 panels, and GC2/GC1 panels running older zwave versions (GC1 aka CP11 2.78 and GC2 aka CP21 3.42), are not compatible (or any event, not fully compatible).
latest Zwave version started with Panels with factory 1.13 firmware I believe
This is why I always tell people to NOT be early adopters of new gear/equipment.
I imagine there will be many 2GIG users who invested in the RTS that do not have the correct zwave firmware to actually use them. Basically, unless you bought a brand new GC2 after April 2015, you don’t have the correct zwave version.
In my case, My panel was purchased Oct 31, 2014 (16 months ago)…less than 6 months prior to the 1.13 release, and is on zwave version 3.42.
2GIG support still refers to it [GC2 with 4.55 zwave] as a CP21. I’m awaiting a solid date code when z-wave version changed.
Then that is problematic. How can one purchasing a new GC2 confirm they are receiving the newer hardware version with zwave 4.55 versus 3.42 if packaging and model are identical? verify that factory firmware is 1.13 or higher?
Problem with that is most dealers may simply update the firmware in house prior to retail/shipping.
We’ve made requests for updated documentation on the RTS, but more specifically, from 2GIG on when the latest Zwave version was first shipped.
Unfortunately the RTS is the first and only such compatible device to have this requirement. Defining compatibility by firmware works for the other two compatible panels for the RTS (Simon and Concord) because their module firmware cannot be upgraded and Zwave version is tied to the module. Replacing the module assures both.
New panels show 3.42. Unfortunately, ADC is not referring to the Z-wave Version listed in the panel version screen. It is an internal build version. 2GIG does not release details about it (apparently not even readily to ADC) but generally, all GC2’s should be compatible.
It’s likely that it lines up 1 for 1 with 3.42 in the panel version screen, and they did say that anything with symbols under the emergency button is technically what 2GIG refers to now as a GC2. All GC2’s supposedly have this 4.5X internal Zwave build supporting NWI.
The internal build necessary for the RTS would have had to be available from near the beginning of development for the device I would think, so it makes a lot more sense than a brand new revision.
So, if you have an older panel showing 2.78 in the version screen and the word “Emergency” on the front, the RTS will definitely have problems.
While the answers were not as solid as I would hope, you should be ok with either B or C from your above image.
