Support for Heatit Z-TRM6

Hi All! Greetings to the community!

I have to start by saying that I was able to troubleshoot several issues and implement numerous automations based on the information I found in the community topics, so big thanks to everyone!

I am interested in buying a Z-TRM6. Searching in the community I could not find any mention if there is a driver for this. In the supported devices there is a driver for Z-TRM3 which looks very similar however it does not have a cool mode. Contacting heatit support I got the following reply "If the Hub has a general integration with Z-Wave devices then it should work as long as it is in multichannel." Does anyone know if the existing driver for the Z-TRM3 will work? If not could it be updated to work with Z-TRM6 as well? In addition would the generic thermostat z-wave driver work as an alternative in this case supporting all possible modes (heat, cool, auto)?

Thank you for your help!
