Hi everyone,
I’m having a problem that I can’t seem to figure out. I have several multi-button Z-Wave wall switches from Vesternet. I previously had switches from another manufacturer and experienced the same issue. I use these switches to trigger automations, and everything works perfectly otherwise. However, the problem is that sporadically (sometimes once a week or once a month, and especially at night, all the buttons on all the switches suddenly activate simultaneously. I end up waking up at night because the window shutters are opening and closing, etc. Does anyone have any idea what is happening here and how I can stop it?
I only paired the roller shutters with HA and the Home Center 3. I didn’t install or delete anything and I’m really at a loss. I think I’ll disable all automations at night so I don’t get startled…
I hope someone can help me, the battery level is at 100% for all the wall switches, and the manufacturer can’t help me either, please help
I just found something: my Aeotec Gen5 Z-Wave USB stick apparently checked for or requested a firmware update at exactly that time. I’m not sure which, please see the screenshot. At that precise moment, all the wall switches suddenly became active; essentially, if you disable and then re-enable a wall switch in Home Assistant, exactly the same thing happens …
It looks as if the stick was searching for a firmware update and then restarted or so I suspect. I’m not sure if disabling the firmware entity actually achieves anything…
I’ve programmed the buttons to trigger specific actions: opening and closing the roller shutters, setting the heating thermostats to 7 or 28 degrees, and opening and closing the garage door nothing else. I don’t understand what that has to do with it; it happens even when I delete all the automations from the keys.
The manufacturer contacted me and gave me the crucial tip,
quote:
The problem is actually down to how your smart home hub handles automatic Z-Wave “wake-up” reports, especially during scheduled nightly maintenance. Battery-powered Z-Wave devices go to sleep to save power and periodically wake up (often overnight or every 12–24 hours) to send a quick “I’m alive” wake-up report and battery update to your hub. When your switches wake up, your hub is misinterpreting that background report as a physical button press on all channels at once, which fires off all your automations.
Refine your automation triggers: This solves the issue in almost all cases. Check the triggers for your automations in your hub. Ensure they are strictly set to look for a Central Scene action (specifically “Key Pressed 1x” or a single button press) rather than a generic “Device State Changed” or “Any Update Received.” If the trigger is too broad, any wake-up signal will trip it.
I’ve defined the automation = event type KeyHeldDown, so that I have to hold the button for at least 2 seconds. I think that’s the solution, I’m curious to see. Thanks.
