Problem with Z-Wave association to Fibaro 2 relays switch

Francois Lesueur 10 months ago in Devices / Z-Wave updated by ComfortClick Support 10 months ago 1


I'm running bOS 4.7 on Jigsaw KNX with a Z-Stick. 

I have many Fibaro modules in my set-up, including a Fibaro fgd-211 dimmer, and a Fibaro fgs-221 2 relays switch. 

Group 2 of the dimmer is connected to a second switch, and can be used to control other devices thanks to group association.

I want dimmer Group 2 to control group 1 of the fgs-221. 

When I set-up the association, I did find the fgs-221 node, but I didn't find each of the relays. So, I associated dimmer group 2 to fgs-221 node. And it did work : I can now control relay 1 with dimmer switch 2. 

However, I'm now having the following error message on bOS when I click on Associations : "La référence d'objet n'est pas définie à une instance d'un objet" which would translate approximatively as "Object reference not set to an instance of an object". And I cannot view / modify associations anymore.

did you try using Reload configuration option on top right?

Also, try simply re-adding the device, seems some node in the device is corrupted or not working 100% with bos..

Best regards,
