Hi everyone,
I’m trying to efficiently control a large number of Z-Wave devices (80+ lights) using Home Assistant with an Aeotec Z-Stick Gen5 and Z-Wave JS integration. My setup is mostly Fibaro Dimmer 2 (FGD-212) controlling different light sources.
When I try to control all devices at once, I experience severe performance issues, which sometimes results in some lights remaining on due to the network being overwhelmed.
I have tried to reduce the Z-Wave network load by using Z-Wave associations so that I can configure master devices that can turn off associated devices directly.
What works:
- Physical activation of the master Fibaro Dimmer (e.g., pressing the switch) turns off all associated devices, which proves that the associations are correctly set up and working for device-to-device communication.
The issue:
- When I send a
light.turn_offcommand or usezwave_js.set_valuefrom Home Assistant to turn off the master device, only the master turns off. The associated devices don’t follow, and it seems that Z-Wave associations are not triggered when commands are sent from the controller (Home Assistant).
What I’ve tried:
- I’ve set up associations in Group 2 (for Basic Set commands) in the Fibaro Dimmer 2 via Z-Wave JS UI.
- I’ve used Multilevel Switch (command class 38) in automations, but while the master device responds, the associated devices don’t.
My question:
Will the use of Association even relieve the Z-wave network trafic?
If so, Is there a way to make the Z-Wave associations trigger from controller-initiated commands like light.turn_off or zwave_js.set_value in Home Assistant?
If associations won’t work, does anyone have suggestions for reducing the load when sending commands to a large number of Z-Wave devices?
Thanks in advance for any insights or suggestions!
