Hi
I use a zwave Fibaro Dimmer 2 when autocreated I get ZWave_SWITCH_MULTILEVEL_12
But after some time I also get and after some time it creates me ZWave_Node_12.1 en 12.2 I have n idea why and what I should do with it. Is this normal? What is the reason for this?
Thanks
These devices represent the channels of a device: if a message encapsulated in a "channel package" is received, the FHEM module automatically creates a FHEM device for it.
It also may be a sign for corrupted messages: in certain cases the radio packet is only secured with an 8 bit CRC, if this CRC fails to do its work, then junk readings or devices are created.
This issue might be remedied by using a communication with 100k dataRate (this needs "not too old" devices and good RF connection), or adding the useCRC16 FHEM attribute (if the device supports it by implementing the CRC_16_ENCAP class).
In the latter case the 16bit CRC will be used by FHEM for each message sent to the device. This wont guarantee though, that messages sent _by_ the device are also secured with 16bit.
I have similar things for my Fibaro Roller Shutter:
endpointChildren ZWave_Node_16.1
(maybe I also had a ZWave_Node_16.2 once? Not sure anymore)
I have "CRC_16_ENCAP" and good connection...

Hi
Thanks for the reply
In my FHEM.CG I have:
attr ZWave_SWITCH_MULTILEVEL_12 classes ZWAVEPLUS_INFO BASIC VERSION MANUFACTURER_SPECIFIC SWITCH_MULTILEVEL DEVICE_RESET_LOCALLY ASSOCIATION_GRP_INFO ASSOCIATION POWERLEVEL SECURITY FIRMWARE_UPDATE_MD CRC_16_ENCAP CONFIGURATION SENSOR_MULTILEVEL METER MULTI_CHANNEL_ASSOCIATION MULTI_CHANNEL PROTECTION ALARM SWITCH_ALL APPLICATION_STATUS MARK SCENE_ACTIVATION
attr ZWave_SWITCH_MULTILEVEL_12 vclasses ALARM:5 APPLICATION_STATUS:1 ASSOCIATION:2 ASSOCIATION_GRP_INFO:1 BASIC:1 CONFIGURATION:1 CRC_16_ENCAP:1 DEVICE_RESET_LOCALLY:1 FIRMWARE_UPDATE_MD:3 MANUFACTURER_SPECIFIC:2 METER:3 MULTI_CHANNEL:4 MULTI_CHANNEL_ASSOCIATION:3 POWERLEVEL:1 PROTECTION:2 SCENE_ACTIVATION:1 SECURITY:1 SENSOR_MULTILEVEL:4 SWITCH_ALL:1 SWITCH_MULTILEVEL:3 VERSION:2 ZWAVEPLUS_INFO:2
attr ZWave_Node_12 use crc16
I guess the addition for crc16 makes no sense as CRC_16_ENCAP is already set. My guess is correct?
*_12 gives me no information about the power/energy used.
*_12.1 gives me information about the power/energy used.
*_12.2 ? I don't know where I can use it for
So there is a logic in it, but I wondering if this is intentional. Maybe I should I include it again?
Anybody else with de Fibaro dimmer 2 has the same?
Thanks for hints
Zitatattr ZWave_Node_12 use crc16
Should be written as "attr ZWave_Node_12 useCRC16 1"

Nope, for using this feature you need both the attribute and the capability.
