2gig ct100: humidity?

Does anyone know if the CT100 thermostat exposes it’s humidity sensor to zwave? I’m guessing no, as I tried to use it in a smartapp and it found no sensors. But I’m not a coder and could have done it wrong.

I’m interested in knowing this also BUMP

No, it doesn’t; I use a aeon labs multi-sensor as humidity sensor in conjunction with the CT100; an app takes care of turning on/off the humidifier based on the state of the thermostat, temperature and humidity.
I actually use the same sensor in a different room for presence check and to control a space heater; it works well.

over on the homeseer website, the release notes for a specific version of their software indicate a fix for “2gig ct100 thermostat not displaying relative humidity value.” which would indicate to me that this thermostat is capable of providing this value through zwave.


Some folks are working from the developer IDE. It appears the humidity value is somewhere, we just have to get some help from 2gig about how to find it:


Any updates on this?

Did anyone find a way to extract it?

I’m cross-posting this here from another thread, but in doing some more digging on the whole humidity issue, I came across this from the MiCasaVerde site:

It’s in one of the embedded devices: the one with no temperature. http://<vera_ip>:3480/data_request?id=status&DeviceNum=<embedded_device_num>&output_format=json

            "id": 9,
            "service": "urn:micasaverde-com:serviceId:HumiditySensor1",
            "variable": "CurrentLevel",
            "value": "41"

Just make sure you use the embedded device number instead of the main device number to query the status. Hopefully, they’ll fix the device UI to display the relative humidity in future updates.

I’m guessing you guys have already seen this, but in looking at the logging, I’m seeing:

zw device: 03, command: 3105, payload: 01 2A 02 BC

Any chance there’s a way to access other “devices” that would be part of the thermostat as referenced above? Or is the device 03 the reference for my thermostat on the zwave network? I’ll readily admit that I’m in a bit over my head here, so if I’m completely off base feel free to tell me. Just something I stumbled upon, so I thought I’d mention it.

Oh: here’s the link to the info from above: http://forum.micasaverde.com/index.php?topic=14790.0


Use these codes changes to get Humidity from the CT-100 and CT-101
