[Z-Wave Review] Zooz Mini Plug Sensor (ZEN07)

Continuing on, here is my third Z-Wave module review.

ZOOZ Mini Plug Sensor (model ZEN07)

What is it?

The Zooz Mini Plug is a simple on/off switch. To my knowledge, this is the smallest Z-Wave plug on the market, completely unobstructing the other plug on an outlet.

This device contains a Z-Wave Plus chip, touts a 100 foot (line of sight) range, and includes a 1-year warranty.

Why would I want this?

If you're running a Z-Wave network, you have thought about controlling plugs at one time or another. This Mini Plug is not designed for large appliances, but is ideal for things like lamps, computers, TV's, audio equipment, and more. It will give you the ability to power on or off a device from your phone, on a schedule, or as an action once something else is triggered (i.e., trigger is when motion is detected in a room, condition is that it's after sunset, action is to turn on a lamp).

The Mini Plug has a maximum load of 13A, which is pretty generous. Interestingly, the max load can actually be adjusted down to a lower value, via configurable parameters. It also has a "high load" LED that is configurable at a value lower than the max load. As an example, I have mine setup for a lamp and have it configured for a max load of 12A, with a high load LED notification once it gets a 10A or greater load. Realistically, that should never happen being that it's for a single-bulb lamp.

Another reason is that this device reports load statistics. For me in Home Assistant, 7 sensors were automatically created. The four big ones are Current (in Amperes), Energy (in kWh), Power (in Watts), and Voltage. If I was to have one of these on each electrical circuit in my house, I could totally monitor the voltage of each circuit. I could configure rules to send notifications if the Voltage was to drop above or below a certain level. The Current, Energy, and Power sensors are only for the load on the Mini Plug.

The other reason you want one of these is because of it's range extending attributes. Any Z-Wave Plus device that does not function on a battery, is a Z-Wave network repeater. Place one of these in each room and you will have a solid Z-Wave network, without a doubt!

Does it work?

This is one of the easiest devices I've worked with so far. From a hardware perspective, you just plug it into an outlet and plug some device into the Mini Plug. Press the button to toggle power to the device, and that's it. Z-Wave inclusion was super quick and easy, and while it was supported with Open Z-Wave, there is no configuration currently shipping with Open Z-Wave for this device. I have created that config (thanks to the AMAZING documentation that comes with Zooz products where they clearly list each parameter) and submitted to the Open Z-Wave project, so I expect it to get added real soon.

Without that config you can still toggle power to the device and get monitoring stats with Open Z-Wave, but you are unable to change any parameters. This was actually a great Open Z-Wave learning experience for me.

What's in the box?

Like the other Zooz product I reviewed, I was very happy with the packaging. Basically a plastic tray inside of a cardboard box with the Mini Plug neatly in place, with 2 documentation booklets.

Once you remove the tray from the box, you find the plug and the booklets.

Inside the box

Inside the box is only what you need. The Mini Plug itself, an installation booklet, and an Advanced Settings booklet (this makes me a huge fan of Zooz).

Was the inclusion easy?

For me, it wasn't a typical inclusion because I first had to create the config bindings for Open Z-Wave. While typing this post, I hopped over to the Open Z-Wave github and see that my config has already been merged with this commit. So as long as you grab the latest files, you won't have to worry about anything with Open Z-Wave and Home Assistant.

The actual inclusion couldn't be easier. When you first plug in the Mini Plug, it goes into auto-inclusion for 20 seconds. So all you have to do is stop hass, start ozwcp, set your controller to add mode, and plug the Mini Plug in. It should be picked up and included with just a few seconds. I was able to successfully add this in Secure mode as well, which is a HUGE plus.

If you, for whatever reason, don't feel like using the auto-inclusion, all you have to do is push the button 3 times real fast once your controller is in inclusion mode. That's it

Afterwards, here is what I see in Open Z-Wave Control Panel.

Current values

Likewise, here are the available configuration options, which I made a few changes to.


Within Home Assistant, you should see a handful of sensors as well as a new switch.* device. Since I renamed my module from within ozwcp, and it's node #20 on my Z-Wave network, I see switch.lamp_diningroom_switch_20. I created a new group for my Dining Room and added this lamp to it for manual control. I also plan to create a couple automation rules to turn on the lamp 15 minutes prior to sunset, and off at 1AM local time.

My thoughts

Super happy, no fuss, just works. Quality is really nice, and they only cost like $33 from The Smartest House and $37 direct from Amazon. It's my understanding that The Smartest House is the only authorized seller of Zooz products. I've ordered from them on a few occassions, and every time has been nothing short of excellent. I had originally planned to get a couple Aeotec Switch 6 modules, which are ~$50/ea. Saving $15 per switch is a big deal, at least to me. The only thing the Aeotec Switch 6 adds is a USB port on the side, which I would never use anyway.

My Recommendation

Buy this! There are more reasons to buy then not to buy, and the price is solid! Control lamps and other devices, monitor power usage of that device, and extend the range and reliability of Z-Wave network. No excuse not to buy at least one of these for your Z-Wave network.
