GE Fan Control 14287 Z-Wave Set Configuration Parameters

Attempting to set LED on/off parameter for a GE Z-wave Fan Control. The Parameter in question is 3 and I want to set it to either 0 (on) or 255 (off). I can read the parameter properly, but setting a new value doesn't seem to work. I am using the Modify Configuration Parameter option from the Z-wave menu. Changing the setting manually at the switch (tap up quickly three times, followed by tapping down) does result in a new value being set. Here is the debug logging from the log:

SENT readConfigValue: 01 0A 00 13 11 03 70 05 03 25 3E 99
Z-Wave Debug RCVD requestConfigVal: 01 0B 00 04 00 11 05 70 06 03 01 FF 6F

Z-Wave device "Office Room Fan" parameter 3 changed to 0
Z-Wave Debug SENT readConfigValue: 01 0A 00 13 11 03 70 05 03 25 40 E7
Z-Wave Debug RCVD requestConfigVal: 01 0B 00 04 00 11 05 70 06 03 01 FF 6F
Z-Wave Debug . . requestConfigVal: node 017, parm index 3, value 255 (size 1)
Z-Wave retrieved parameter 3 value: 255 (size 1)

Any guidance on how to make this work properly? As the blue LED is really bright, I'd like to automatically turn it off at night and then back on during daylight. Thanks!

That all looks correct so I'm not sure why it isn't working. Sometimes if the parameter size is set incorrectly it will fail to set, but in this case when you read out the value it shows the size is 1 byte (which is what I would expect for this parameter) and that is what you are using when you write the value so that shouldn't be the problem. You can try using the other size options just to see if that makes a difference or not.

It is also possible the value is read-only and not settable via a Z-Wave command. Not many modules have parameters like that though, and in this case there would be no reason for it to be read-only.

Thanks Matt. I have about six of these and they all perform the same way, so it doesn't seem to be an issue with a single device. I just tried 1, 2 and 4 byte saves without any success.

Some modules also have a configuration parameter to lock the ability to change all the (other) parameters. Not sure if that might be the case here?

Interesting. I can't seem to find any documentation to suggest that there is a lock override (or really any documentation at all that relates to the supported configuration parameters). Do you happen to have any archived docs from this module when you included initial support for it back in 7.3?

I believe this is the web page I used to create the definition.

I have the same Fan Control so I did some testing. You can query a device for the configuration properties of a given parameter. Here is an example for a GE Smart Switch querying for parameter 3:

Sent: 0x70 0x0E 0x00 0x03
Received: 0x70 0x0F 0x00 0x03 0x01 0x00 0x03 0x00 0x00 0x04
This decodes to a min value of 0, a max value of 3, a default value of 0 and the next parameter number is 4.

Additionally, you can query a device for the configuration name of a given parameter.

Sent: 0x70 0x0A 0x00 0x03
Received: 0x70 0x0B 0x00 0x03 0x00 0x4C 0x45 0x44 0x20 0x4C 0x69 0x67 0x68 0x74
This decodes to: "LED Light"

Finally, you can query a device for the configuration info of a given parameter.

Sent: 0x70 0x0C 0x00 0x03
Received:
70 0D 00 03 01 53 65 74 20 74 68 65 20 4C 45 44 20 6C 69 67 68
70 0D 00 03 00 74 20 73 74 61 74 75 73
This decodes to: "Set LED light status"

Sending the same commands to the GE Fan Control returns nothing. I'm not sure why nothing is returned or what it means, but it probably explains why you can't change the parameter.
