Daikin One+ smart thermostat can listen as well as talk to Daikin HVAC systems

By

Daikin, one of the largest HVAC (heating, ventilation and air conditioning) vendors in the world, recently introduced the first full-featured smart thermostat to offer two-way communications with its popular climate control systems.

The Daikin One+ smart thermostat unveiled at the CES 2019 in Las Vegas does everything you expect from this type of smart home appliance. It lets you adjust the temperature by swiping its touchscreen display or turning a hardware dial; set up a schedule for automated temperature adjustments; and activate an energy-savings mode, either manually or by geo-fencing (i.e. it kicks in when it senses that no one is home).

Additionally, the One+ can adjust humidity on Daikin systems that include humidity controls. It can also monitor air quality indoors (on systems with a Daikin One Home Air Monitor), also report on outdoor air quality and weather (when you’ve connected the One+ to the internet).

More importantly, the One+ can receive and respond to communications from Daikin HVAC systems, making adjustments based on this information. Most smart thermostats do not have this ability.

Daikin designed the One+ with several types of users in mind. The hardware dial makes temperature adjustments easy for non-techies, but turning it brings up the adjustment screen on the color LCD display for those who wish to swipe to a specific temperature. A motion sensor readies the thermostat for input as you approach, and tapping the hardware dial brings up the home screen on the display.

Homeowners can also access additional screens for the other settings (scheduled adjustments, away options, and air quality reports). Finally, the One+ has some screens with settings for home builders and HVAC installers and even has a bubble level to aid in installation.

The One+ connects to the internet via Wi-Fi. As with most web-connected smart thermostats, you can also access controls remotely, either via Daikin’s mobile apps (for Android or iOS) or major voice assistance systems (including Amazon Alexa and Google Assistant).

A connected Daikin One+ also allows homeowners to cut energy costs by participating in peak load reduction programs offered by utilities. The thermostat supports the Open ADR 2.0 protocol utilities use for this purpose.

The one downside: You can only install the Daikin One+ with Daikin HVAC systems.

GE expands Cync smart light lineup, adds climate control, camera
GE Cync lights set up in gaming room.

If you’ve never heard of Cync by GE Lighting you could be forgiven. It doesn’t get the press of some other more popular brands of smart lighting. Today, GE Lighting announced several new Cync products that will expand this smart lighting platform to a full smart home ecosystem, meaning if it's not already on your radar, it should be.

As part of CES 2022, the company is introducing a smart thermostat and temperature sensor, a line of outdoor security cameras, and several new lighting products to its family of connected products. A big bonus for many consumers, there is no additional hub or bridge required to create the Wi-Fi connection needed for automation and scheduling.

The Arlo Security System brings all-in-one functionality thanks to its multisensor
The Arlo Security System features an NFC reader.

If CES 2022 is a boxing ring, Arlo has thrown one of the first punches with the announcement of the Arlo Security System, an all-in-one DIY solution to home security. It's not only a 2022 CES Innovation Award honoree, but it also features an all-in-one multisensor capable of eight different sensing functions that include motion, when a door or window opens or is tilted, water leaks, light and temperature changes, and the alarm patterns of T3 and T4 smoke and carbon monoxide detectors.

Perhaps the most impressive part is the size of the sensor. At just 1.1-inches wide, the multisensor is discrete and fits anywhere in the home without hardwiring. A more flexible sensor (with more flexible placement options) means better security overall.

7 things you didn’t know your smart thermostat could do

At their core, smart thermostats can learn about when you're coming and going and adjust the temperature automatically. Over time, however, smart thermostats have leveraged their intelligence to do some interesting things well beyond that basic mission. Let's dig into some of the more obscure features we're seeing in the latest smart thermostats. Who knows? Maybe you'll learn something you didn't know your own smart thermostat could do.
Adjust for sun exposure
If your thermostat is exposed to sunlight, it can skew the ambient temperature reading. The little spot the thermostat inhabits could be a fair bit warmer than the rest of the home. This means either heating could be prevented from turning on automatically, cooling will be prematurely activated, or the overall data on your home's heating and cooling status will be inaccurate.

Some manufacturers, like Nest, have built in a feature that counteracts this artificial spike in temperature reading. Since many smart thermostats have light sensors to automatically adjust the display brightness, they can also be used to see if there's an overlap between when brightness increases and when an abnormal spike in temperature is read. Once it figures out how much the temperature increases in that span of time, it can automatically reduce the reading to get something more accurate for the rest of the house.
