Help / Ideas Wanted - Wireless Jabra Headset & "On Air" Lights

Ey up all,
thanks in advance for looking and apologies if I’ve mansplained

I’ve got a Jabra wireless headset connected to a work laptop via a Jabra Lunk USB dongle thingy .

I have 2 x WiFi multi-coloured USB lightbars. One downstairs on the fridge and another on my office door.

I want the lightbars to turn on and red whenever I’m in a call, as this prevents anyone entering my office or shouting up the stairs.

I’m currently using a crude but simple aquara contact sensor to automate this; the sensor part stuck to the headset stand (where the headset rests) and the magnet part celotaped to the back of the headset so it’s not visable on videocalls.

I also have to go into the office from time to time and so, I have to unstick the magnet part from the headset and stick it to the sensor part. Then I have to remeber to stick it back to the headset, lest someone shouts up the stiairs or barges in whilst I’m on a call the next day.
*I’m not good at remembering to do it

Is there a better way of making this work without the need to stick / unstick anything to the headset etc?
*assume that I can’t install any software on the work laptop nor can I export my calendar etc. It has to be done via a sensor of sometype.
*also assume I have Zigbee, Zwave and Bluetooth and a 3D printer to play with but, I’m not an absolute Home Assistant genious
*the automation should only work when I’m wearing the headset, I leave it powered on all day and there’s a 15 minute sleep timer on it so tracking it witrh bluetooth wouldn’t be as effective.

I was thinking weight sensor or some kind of crappy webcam looking for a white spot I’d paint on top of the headset stand which would be covered up by the headset when it’s on the stand.

I’m not bothered about the automation firig when I pack the headset into my work bag as it only fires whenever a “working from home” event is detected in my personal calendar.

Thanks again in advance.

I have sensors from my work pc that I can use to determine if I’m in a meeting.

That’s an ok solution however, it doesn’t allow for phone calls and watching of training videos etc. I need something that just detects if the headset is on the stand or not on the stand.

I’ve had another thought about this…

If I use a Zigbee leak sensor and attach it to the top of the sand with tape or a glue gun:

Then add a strip of black conductive tape to the underside of the headset headband

When the headset is resting on the leak sensor It should bridge the dry/wet contacts and register a leak i.e. the headset is on the stand.

When the headset is not on the stand / leak sensor, the black conductive tape should be almost invisible to people in the office when I take my headset with me.

I’ve ordered the materials and will update with photos when finished. I might need to also use the glue gun to build up layers on the leak sensor to guide the headset into the middle of the contacts.
