Z-Wave Thermostat for HS2

I have an old Wayne Dalton WDTC-20 which has always been somewhat problematic and would like to replace it with a new battery operated thermostat.

The GoControl TBZ48 would fill the bill but HomeSeer informed me that they have never tested it on HS2.

I am running the last HomeSeer 2 version, HS 2.5.0.81 with a ZTroller at firmware level 1.17.

Is anyone running a TBZ48 on HS2? Any other recommendations for a battery operated thermostat for HS2? TIA
