See the Cubes in action in HardWired’s Smart Home episode

by Alja Isakovic

As gadget fans, we love watching iJustine’s HardWired show, in which she explores the hottest tech from around the world. So you can imagine our excitement when the HardWired team asked us if we could send over some Cubes for iJustine to play with!

You can now watch The HardWired 2.0 Smart Home Tech episode below. Among other cool home gadgets, iJustine gives a great demo of the Cubes and says: “CubeSensors are great for giving you overall stats on your environment”. Thanks, iJustine, and don’t forget to open the windows regularly to keep the Cubes happy :)

If you want to get your own set of Cubes by the end of summer and keep your home healthier, you can still order a pack directly from our website.

New investment for CubeSensors and support for bitcoins

by Alja Isakovic

We’re excited to announce that CubeSensors has just raised a seed investment round from the cofounders of Bitstamp, the world’s largest Bitcoin exchange. We’ll be using the investment to grow our team, scale up production, and work on new products. You can read more about this news on our press page.

In other words, this will help us get the Cubes into your hands even faster! We know you’ve been waiting patiently for the second batch to start shipping, and we’re working hard on packing all the new Cubes we’ve been making and testing in the past few weeks. The first few dozen packs are already traveling around the world as we speak, and more will join them every day.

We also have some exciting news if you haven’t yet ordered your pack of Cubes or want to order an extra set for a friend or the office. Starting today, you can also order CubeSensors in bitcoins through BitPay. We of course still support orders in USD, GBP and EUR through PayPal, so head over to and order the Cubes in your currency of choice today. We expect new orders to ship in late summer this year.


What do the Cubes go through before reaching your home?

by Alja Isakovic

Ever wondered how your CubeSensors are made? What kind of tests they go through before we ship them out?

It all begins with a small, white printed circuit board (PCB), packed with sensors. We attach a battery to each board and set it up with a special firmware that makes sure to “burn” the Cube’s air quality sensor for 3 – 4 days. This makes sure the sensor self-calibrates faster in your home.

After that, another setup firmware is loaded, which quickly charges, discharges and recharges the battery on the Cube. This helps us to identify batteries that don’t perform as expected and any sensors that don’t work properly. The whole process takes about 2 days for each Cube.

Once the Cube candidates pass this initial test, we load them with the almost final firmware, put them on charge again, and let them automatically update to the firmware we’ll ship them with. During this phase, we pay even closer attention to the measurements, sent by each of the sensors. If anything appears off, the Cube can’t connect to our crowded ZigBee network or doesn’t go through the update, we take the Cube out of the process for a closer inspection.

For the majority of the Cubes that make it through setup and the update, it’s now finally time to actually become Cubes. We glue all the parts together, and let the Cubes settle over night. The next day, we charge them one last time and do one final check of the measurements before cleaning and packing them up. After that, we just make sure they are turned off for their last journey to your home or office, where they are immediately ready to start making you feel better.
