This will be a thread for listing out any bugs you may find and/or any enhancements you’d like to see for the Blue Series mmWave Switch (VZM32-SN). This is not a thread for troubleshooting personal problems – please create a new thread so we can properly help.

Using the visualizer someone made in this thread to try and help debug my issues and it appears that the switch will clear occupancy even though the target is still visible as seen in this screenshot. [Screenshot_20260127_151137_Home Assistant] The dot is very accurate for where I am standing exc…

Note that the switch does not send an “all clear” when it no longer sees a target (if it doesn’t pick up any other targets), so any tool that just continues to show the last received message will have “phantom” targets like this. Trust the In Area reports showing that the areas are all empty, rather…

I just want to confirm with your tool if there is more than one person in the room I should be seeing more than 1 target correct? I’m just trying to make sure everything is working properly on my switch before I start rolling it out to other rooms in my house. So far I’m just seeing one target. Also…

Settings question, 113 mmWave Trigger Speed (Red verbiage) 113 mmWave Detection Delay ( Blue verbiage) To control how quickly the sensor responds after detecting presence on the Blue Series mmWave Presence Dimmer switch, find parameter 113 in your hub’s UI and change accordingly. The lower the n…

Has anyone else been able to get a scene set on a VZM32 for a group? I have no problem doing this with my VZM31s, but I just tried to add a VZM32 to a group scene today, and I keep getting INSUFFICIENT_SPACE in zigbee2mqtt.

So I’ve noticed that my switch is rather warm to the touch compared to other switches. Has anyone else noticed this? Is this normal? I checked all the connections to make sure they are properly seated and they are. I have a dumb switch for my fan right next to it and its much cooler to the touch. I …

[image] darkstarsetter: Is this normal? Yes, the mmWave sensor is right under the paddle. The switch monitors the internal temperature and has overheat protection.

So I was trying to get the system to not turn on the lights when not needed by changing from using the built in occupancy to using home assistant to control the light based on occupancy and light level. While the light I found to now be .5-1 second slower (not unexpected) the issue I now was gettin…

I’ve been seeing weird behavior with the mmWave params. It seems that only the pre-defined room sizes work properly, and was also seeing unexpected behavior for StayLife as well (setting a very high value with low sensitivity still turns off occupancy after a short while when motion stops but has no…

Exciting update which adds Z2M configuration of mmWave Stay Areas. Thanks @EricM_Inovelli and team! I think I found a bug: I noticed that when I would try to adjust “Stay Area 1” WIDTH parameters, they would not apply as expected. It seems like it would swap min/max and also +/-
