Based on your comments and the manual, I does look like the entry in the device database should be updated. Would you agree that all of the configuration parameters should have a range of 0-255? I do not have the device to test the changes, but I can easily get this sorted for you.
In looking through this further, I do not see a parameter 0 or 4 in the manual. Should these be removed? There are also a few other parameters listed. Do these apply to this device?
You could test them to see if they do anything, but the descriptions are really vague, they aren’t im the manual, and I don’t think parameter 0 is even possible. I just deleted them, and I also found a few more parameters in the manual. You’ll need to wait for the next build, update the binding, and delete and rediscover the Thing for this device.
