All:
I recently bought a Z-Wave thermostat - an American Standard / Trane model AZEMT500BB32MAA. I wanted one that looked just like my old RS-485 serial RCS thermostats, but also measured humidity.

Looking at the PCB board inside the case, the thermostat is actually made by RCS. When I included it into my system (controller = Z-Net running F/W 1.0.22), it would say the include went successfully, and it added 8 devices (root device + 7 subdevices). However, one of the devices would say status unknown. When I looked in the log, I would see messages like this:
I would occasionally see similar messages about air temperature. After reading various forum posts, I ran the Z-Wave Controller "Scan Existing Devices (Full Scan)" action -- this replaced the "Unknown" device with the measured Temperature. Yay! But I would still get the occasional Relative_Humidity messages shown above; from that I assumed that the thermostat did indeed transmit measured humidity values, but at Inclusion the HS Z-Wave plugin didn't determine that the device supported sending humidity. I can only assume that the Z-Wave SENSOR_MULTILEVEL Command Class must be hard to determine how many such values are reported by the device, or is inconsistent across device makers.
Even though the HS web site says that all Trane Z-Wave thermostats are supported, I couldn't get the humidity values from mine. Based on more old forum posts, folks said they had been able to get some Z-Wave functions added to HS by waiting until the time the device was going to transmit a value, then they did a Z-Wave scan during that time. But how did they know exactly when those times were? Maybe for battery-powered devices that only "wake up" on some sort of regular schedule, but that was a little too much for me to deal with. So, I made an assumption that the thermostat transmits humidity and temp values whenever those values change; I sped up that process by heating the air around the thermostat with a heat gun and then did a rescan. It took a few times, but eventually HS added the humidity subdevice! I borrowed a different device that measures temperature and was able to Include its temp function in the same way.

So, it would be great if HomeSeer would support all device functions "out of the box", but this "kludge" might help - It would be great to know if this helps you too.
