I have purchased 5 units (have 1 unit of the first generation) that I am not able to connect to Homey :-/ > I will be happy to contribute to your PayPal! @Dais Thanks! The ThermoFloor / Heat-it app is my last SDK1 app. Before extending it with new products, I will need to convert it to SDK2; it doesn’t make sense to define new drivers on a SDK version that is no longer supported. Thermostats are one of the more difficult drivers to setup, because it involves quite some device specific logic that needs to be embedded into the driver… I just finished creating a SDK2 version of a Z-wave thermostat for the Remotec ZXT-120 and ZXT-600, which I created with the ThermoFloor / Heat-it thermostat in mind. It should be possible to re-use 95% of the code for these devices. So first I will need to re-write the existing app to SDK2 version, before I will be able to extend the support for additional devices. Coarse timeline I have in mind is to finish the SDK2 re-write in September and add support for the remaining devices (Z-therm / Z-scene controller) in October (before the winter starts)… --- _[View the full topic](https://community.homey.app/t/heatit-z-wave-app-v2-7-1/166)._
