After a few years of dipping my toe in the water I’m finally going full steam with migrating to Home Assistant. Multicast functionality with ZwaveJS is amazing, I can almost instantly turn on/off all my lights in the house and I’ve been struggling to implement the same for notifications. With @kreene1987 help, I can now update every notification on every red series dimmer almost instantly. I have constant notifications set, so all my switches are constantly displaying a state (alarm is armed, something is open, person detected on property, all clear, etc). This method is MUCH faster than anything else I’ve tried including bulk set partial param method. Hopefully this helps someone else, here are my setting under scripts. I prefer Mode as “Single” but command class and property should be the same for the red series dimmer and for the value use the calculator Inovelli Switch Toolbox
If you are getting an error when attempting to multicast to your switches confirm in the zwavejs2mqtt control panel that your switch has the additional config paramater on it as seen below
If that param is missing, it is because zwavejs2mqtt is missing this in the config, you can add it manually as documented in this thread or force create by sending a bulk partial param config command to all the switches like this
after all your switch LEDS change to reflect the change you will need to restart the zwavejs2mqtt server and you should now see the additional param added for your switches.
