'ZDNet Recommends': What exactly does it mean?
ZDNet's recommendations are based on many hours of testing, research, and comparison shopping. We gather data from the best available sources, including vendor and retailer listings as well as other relevant and independent reviews sites. And we pore over customer reviews to find out what matters to real people who already own and use the products and services we’re assessing.
When you click through from our site to a retailer and buy a product or service, we may earn affiliate commissions. This helps support our work, but does not affect what we cover or how, and it does not affect the price you pay. Neither ZDNet nor the author are compensated for these independent reviews. Indeed, we follow strict guidelines that ensure our editorial content is never influenced by advertisers.
ZDNet's editorial team writes on behalf of you, our reader. Our goal is to deliver the most accurate information and the most knowledgeable advice possible in order to help you make smarter buying decisions on tech gear and a wide array of products and services. Our editors thoroughly review and fact-check every article to ensure that our content meets the highest standards. If we have made an error or published misleading information, we will correct or clarify the article. If you see inaccuracies in our content, please report the mistake via this form.
You're frequently on Zoom, Teams, Google Meet, or other audio/video calls. Or perhaps you need to remain focused on your tasks for hours at a time. You may wear headphones for privacy or isolation.
However, working this way, it's hard for someone in another room to know when you are on a call or are focusing. Many of us work from a home office, which could be in a multi-purpose space, such as a bedroom or living room, that others may also use, so you don't necessarily have exclusive access to that space.
Eventually, the dreaded thing happens -- a family member walks into the room and interrupts you when you are in focus mode or on video or audio with other people.
Some remote workers may have established a protocol with their housemates and family, such as being told not to open a door without knocking. And this might work some of the time, but not all of the time. In my case, my wife frequently comes in to check on me for various reasons. More often than not, I am wearing my AirPods Max headphones and she can't hear what is going on, and -- because of the noise cancellation -- I can't hear her coming either. Additionally, until she walks up to my desk, there's also no way for her to know if I am on a conference with other people.
Existing business presence solutions
Work from home interruptions are so commonplace -- barking dogs, screaming and crying children, and doorbells going off from deliveries -- that we've become accustomed to them and accept them as a price of dealing with this pandemic. But we still want to minimize them, if possible.
Ideally, it would be good to have some sort of presence indicator or "On the Air" light that can alert someone approaching your office space that you don't want to be disturbed.
There are, of course, various manual "On Air" lights that resemble the kind that existed in TV and radio studios in decades past, but most of them require mounting in a convenient area near an electrical source. There are also hangable signs but that isn't entirely foolproof because if someone isn't looking at the doorknob, they can easily bypass it. And even if they are mountable on the door at eye level, it's also easy to forget to hang one of these up or to slide it into the "DND" position.
My initial solution was mounting a cheap wireless-controlled puck lighton my front door with double-sided adhesive. It uses three AAA batteries that last about 50 hours. That's wasn't ideal. I probably would have to replace those batteries once a month, and I also have to remember to turn the lights on and off between calls. They do have rechargeable ones, but the charge on those products doesn't last very long.
As far as tech products go, there are "presence indicators" such as the Jabra Evolve headphones that will light up red while in use (as they are conference software-aware) to alert the approaching person that you shouldn't be disturbed. There are also USB-connected presence lights such as the Kuando or Blynclight but unless you are using a long USB extension cable to mount these outside your office, said interrupter(s) are already in the room with you and have probably disturbed you already.
These products were originally designed for larger shared working spaces, such as cube farms, not home office scenarios. There are a few wireless, rechargeable devices on the market, such as the Luxafor Bluetooth and Blynclight Wireless, which can be mounted outside your office and are integrated with conferencing systems and calendar schedulers. Still, these two products are either poorly reviewed or are no longer available.
Home automation jury-rigged solutions
There are some ways to jury-rig this by using a combination of home automation components and smart assistant/speaker devices, such as with Amazon Echo/Google Home/HomePod Mini and with smart switches, and smart bulbs/smart lamps.
The Echo Glow (see video) may not be a bad solution if you can put it on a table outside your office and you are an Alexa household, and Philips Hue has the Bloom and Flourish that may also fit the bill. Zigbee-based smart bulbs also might not be a bad idea, as long as they are connected to a compatible smart hub.
However, this solution is entirely manual; it isn't integrated with calendars or conference software – yet. I'd like to see an Alexa skill that combines this somehow so that if I have a block of time marked off as a conference call, it will set the status red on the light. Perhaps this can be achieved with a service like IFTTT, but I'd rather see an out-of-the-box solution.
My dream work presence device
Here is what I think a lot of folks, including myself, would want to see built:
A device the size of a large smartphone that can be easily mounted to the front of a door or on the wall of an adjoining hallway, such as with a magnetic bracket
The device would have a large enough (2"-3" across) array of LED lights for 3-4 colors (Red, Green, Yellow, Blue), which would be visible from 15-20 feet away, that could be behind a larger transparent diffuser. A programmable LED message screen would be nice but not required.
An optional motion sensor would cause the device to light up when someone was approaching rather than running all the time (for battery conservation). It would also alert the remote worker that someone was coming via push notification.
It would have at least 100 hours of battery life before recharge.
Fast USB-C/Qi rechargeable with AC adapter for wired use.
Wireless controls with Zigbee and Bluetooth Low Energy, so that it could be integrated with multiple vendor home automation systems and also direct device controlled (Smartphone, PC/Mac) and with a simple desk remote.
Open-source API development kit.
Out-of-the-box integration with Zoom/Microsoft Teams/Google Meet and Google Calendar/Apple Calendar/Outlook integration.
Alexa/Google Home/HomePod integration.
This is a new category of product that I would love to see a company like Poly, Jabra, Microsoft, or even Amazon itself create. What do you currently use to stop home office work interruptions? Talk Back and Let Me Know.
