I am using VTM30-SN Smart On/Off Switch + Humidity Sensing with Home Assistant v2026.3.3 and device firmware v1.0.4r3. Here’s my question: I’d like to configure some sort of a “maximum run time” i.e., if someone switches on the load manually with the switch, or the switch is switched on from HA and loses connectivity with HA, the switch should turn off automatically after the “maximum run time” duration has elapsed. Is this doable?
I was playing around with “Advanced Timer” setting but that doesn’t seem to do anything. Any thoughts on how to configure an “off delay timer?”
I don’t know how much parity there is between the different lines of switches (White/Blue/Red), but on the Blue switches (and in the documentation of the upcoming Red On/Off switch), Parameter 12 is the Auto-Off Timer.
Assuming this parameter exists for the White switches, I’m not sure of the best way of going about setting it though. I don’t know if this is available and you are just looking over it? or if it doesn’t even show up for the White switches. If it exists, and there isn’t a way to set it through HA, you might follow the Local Configuration instructions and try to set parameter 12, keeping in mind that you may have to factory reset the switch if this doesn’t work the way you hope.
Parameter 12 is set in increments of seconds, so in line with the instructions linked above, if you wanted to set a 5 minute auto-off timer, you would have to go to that parameter and press up on the paddle 300 times (to set 300 seconds) before saving the value.
I would hope there was an easier way to set this, but this is assuming that this parameter is implemented in the firmware.
Thank you everyone. As for automations, while it doesn’t happen frequently, but in those rare cases where HA loses connectivity to the switch, I want the switch to turn itself off regardless of it being connected to HA. Of course, an automation will be useless in a such a situation. Unfortunately, this issue occurred today and am looking for a solution.
@EricM_Inovelli@Kaleb_Inovelli - are there plans to add an Auto Off Timer capability to VTM30-SN? If not, this thread sounds like a feature request.
Is there something about Matter or Thread that makes it infeasible to add this capability? If not, then this is well aligned with the 2026 roadmap because it improves feature parity (e.g., Red dimmers have Auto Off Timer and countdown bar) and pushes forward on Matter.
My scenario for white on/off switches is bathroom fans. The advanced timer mode is interesting and the countdown bar is awesome, but there’s no way my family will remember to 2x or 3x tap. I’d like to replace the Zooz switches that control these fans and Auto Off Timer would unblock me.
All Matter lighting devices (and these switches count as lighting type devices), support the Matter “OnWithTimedOff” command which sends both a “on” to the switch as well as a duration. After the duration expires, the switch turns off.
I wrote some drivers for Hubitat that makes use of this command, so I know it is in the Inovelli products. However, I don’t think there is a way to send this command from Home Assistant . Consider making this a Home Assistant feature request.
As a practical solution, what I’ve used a combination of 3 automations to get “close” to this function:
A first automation that turns any of a list of entities off after 20 minutes.
A second automation for those same entities that looks from a transition from the “unknown” state, and then turns the device off. This takes care of the case where a device was disconnected for some reason and then reconnects.
A third automation that runs on a re-start of Home Assistant that turns the entities off on restart.
The obvious issue here is this 3 automation solution doesn’t work if the device remains disconnected, but for my purposes, that rare event isn’t a problem for my use cases.
As @jvm33 this is part of the matter spec and hopefully it can be exposed in HA eventually. As for advanced timer mode I am kind of in the same boat. I use it but the family doesn’t. I have considered altering it or adding another option to have 1x click activate it. That way it will run by default when you single tap it but you can increase the timer by multi taps. Something I have been considering for some time.
I managed to get a usable “OnWithTimedOff” script for Home assistant, and while it triggers hardware based timing, it does not trigger the countdown animation
# /config/matter_timer.py

async with session.ws_connect("http://core-matter-server:5580/ws") as ws:

greeting = await ws.receive_json()
# Step 2: Send your validated hardware instruction
await ws.send_str(json.dumps(payload))
# Step 3: Wait for the actual execution response back from the switch
response = await ws.receive_json()
# Check the server response for success
if "error" in response:
print(f"Error from Matter Server: {response['error']}", file=sys.stderr)
sys.exit(1)
else:
print(f"Success! Hardware timer sent. Switch Response: {response}")
if __name__ == "__main__":
if len(sys.argv) < 3:
print("Usage: python3 matter_timer.py <node_id> <seconds>", file=sys.stderr)
sys.exit(1)
asyncio.run(send_command())
That, and the functionality is there, might as well use it.
I’d like to replace the Zooz switches that control these fans and Auto Off Timer would unblock me.
