Sometimes the good ones don't make it

The smart home category is taking off with plenty of success stories like the Amazon Echo and the Nest Learning Thermostat, but that doesn't mean all of our favorites made the cut. 

Plenty of smart home products that we liked or were excited about have been discontinued. Either the companies that made them moved on or went out of business. We're not counting products that have simply been upgraded.

Here are the ones that got away. Here is the smart home's graveyard.

Arist Coffee Machine

A cool-looking gadget that never quite came to be, the Arist Cafe offered high-end coffee you could customize from an app. Arist could make espresso as well as coffee, and you could control the water temperature, grind size, brewing pressure and more with the app to please your inner barista.

Delta Leak Detector

Smart leak detection is a useful feature, and a number of devices pull it off well. The Delta Leak Detector showed promise with a nice design, simple setup and feature-rich app, but it was ultimately too expensive and didn't integrate with enough other smart home gear. 

Delta pulled it from the market in July and stopped supporting the app.

Edyn Garden Sensor

What was supposed to be the perfect smart garden assistant, the Edyn Garden Sensor instead had a shallow and slow app. The Edyn Sensor certainly looked beautiful, but it did too little for how much it cost. 

Now it and a number of other plant sensors are nowhere to be found

Goji Smart Lock

Goji's smart lock combined the functionality of an automated deadbolt such as the one from August with a built-in cam that could function as a smart doorbell like the model from Ring.

The concept was pretty cool, and Goji's 2013 crowd-funding campaign came on the early side of the smart lock category as a whole. Alas, it never came to fruition and the startup behind the device never shipped the Goji Smart Lock.

Halo+ Smart Smoke & Carbon Monoxide Alarm with Weather Alerts

Halo+ made it to production. In fact, we were able to review the retail version of the smart smoke alarm and gave it positive marks. The $130 gadget sensed smoke and carbon monoxide, as you'd expect, and sent you a push alert when it smelled something amiss.

Halo's Alarm also had unique weather awareness, so it could warn you of incoming inclement weather. I expected the feature to be annoying, but it was customizable enough to be helpful, especially if you like turning your phone off at night. 

Ultimately, the startup Halo Smart Labs didn't have the resources to continue making and supporting the product, so the company closed its doors. If you own a Halo, you can still keep it functioning if you connect it to a compatible smart home hub.

Honda Asimo

Honda's human robot always felt ambitious. Asimo had moveable arms and legs. It knew sign language and could run and kick a ball. 

Honda might use the lessons it learned from Asimo on other future robots, but the company said goodbye to the iconic bot this June.

Admittedly, we were never very excited about the Juicero. It cost a bundle and made you shell out even more for an exorbitant subscription to proprietary packs of fruit and vegetables. The cold-press organic juicer did garner a lot of hype, however. 

Given its price and limited functionality, the demise of the Juicero makes sense, and the company shut down in the fall of 2017.

Korner Home Security

Korner offered a reliable home security setup at a relatively affordable price. We liked the system, but it was pretty simple and required you to pay a yearly fee starting starting your second year. 

The company announced it was shutting down in June, with its servers closing a month after that. Korner's cleverly designed door sensors are now just door decorations.

Mayfield Robotics Kuri

Kuri charmed me when I met the adorable household robot at CES in 2017. You could give voice commands to Kuri and it would respond with adorable chirps and expressive eyes. It also had cameras behind those eyes and wheels at its base so it could roam your home while you were away looking for anything out of place.

Unfortunately, Kuri was never meant to be. Startup Mayfield Robotics had to cease production a couple of weeks ago and cancel all preorders after it was unable to scale up to retail.

Parrot Flower Power

Speaking of lost plant sensors, the Parrot Flower Power was another popular one that you can no longer find on the market today.

Quirky Porkfolio

If this is the first time you've seen this adorable, smart piggy bank, take a deep breath, you can actually still find it online. We were surprisingly fond of the Porkfolio in our review, but the company that made it -- Quirky -- won't be coming up with creative projects like the Porkfolio or the Egg Minder any longer. 

Quirky filed for bankruptcy in 2015 and sold off its Wink smart home platform.

Revolv Smart Home Solution

One of the first smart home hubs on the market became an expensive brick after the Alphabet-owned Nest Labs acquired Revolv, then shut it down. 

The device allowed you to connect and control multiple smart home gadgets at once, a feature now made relatively common by other hubs like the Samsung SmartThings hub, but at the time, the Revolv was pretty unique.

Nest Labs turned off the hub's functionality in 2016, forcing customers who bought it to look for another option.

Sansaire Sous Vide

Another popular Kickstarter project, the Sansaire Delta never made it into the hands of backers, which was all the more surprising as Sansaire had already successfully made another immersion circulator.

Like other circulators, the Delta attached to most pots of water and maintained a consistent hot temp so you could cook using the Sous Video style. Seal your food, put it in the hot bath, and let it sit for awhile for perfectly cooked and tender meats, veggies or whatever you'd like. 

The startup Sansaire shut down operations in February after issues with the manufacturer. It's still offering some support for existing Sansaire units, but it issued refunds to those who ordered the Delta.

Teforia Infuser

While the Teforia Infuser looks like a luxury device you might like to have on your counter, we never thought paying $1,500 for a robotic tea maker sounded like a great idea. Even in practice, the Teforia Infuser couldn't win us over. The tea was good, but not worth $1,500.

Last fall, the company closed down, so you no longer have to wonder if there's something you're missing from a $1,500 tea maker.
