I recently purchased the MOES WiFi thermostat for my boiler in order to have remote control and integrate it with my ALEXA and GOOGLE Home devices. The thermostat arrived in a small cardboard box containing the white thermostat unit, a set of 2 screws for installation, and a small instruction manual, unfortunately only in English.

In terms of appearance, the WiFi thermostat is an embedded unit with external dimensions of 8.6 x 8.6 cm and an embedded part with dimensions of 5 x 5 cm. The design of the unit is elegant and it feels solid and well-made. The materials used and the precision of the connection terminals at the back are of high quality.

The thermostat features a touch screen display with good definition (black characters on a backlit white background). The only drawback is that the screen is slightly polarized, requiring the user to be at the right angle for perfect visibility of the displayed information.

Before installing the MOES WiFi thermostat in my wall, replacing my old surface-mounted thermostat, I connected the necessary electrical connections to test its functionality. The thermostat allows for programming 6 time slots with associated temperatures for each of the 5 working days (Monday to Friday), as well as 6 time slots with associated temperatures for Saturday and Sunday.

In manual mode, using the touch screen buttons, the thermostat functions as expected. The relay switches on correctly when the ambient temperature is below the set temperature, and the programming of days and hours is accurate and displayed correctly on the screen.

In WiFi mode, using the SMARTLIFE application downloaded from GOOGLE PLAY or APPLE STORE, the implementation of the thermostat was a bit difficult due to the lack of clear instructions in the provided manual. I had to struggle a bit and also consult the online help provided by the SMARTLIFE application during installation. It's worth noting that if your WiFi router's password contains spaces, the SMARTLIFE application will not proceed, so you will need to change your router password accordingly.

However, once the installation of the thermostat in WiFi mode was completed, the device worked perfectly, just like in manual mode, but now with the convenience of controlling it through the SMARTLIFE application on a tablet or smartphone.

I haven't been able to test the thermostat with ALEXA or GOOGLE HOME yet, as I don't currently own these devices. I will publish my tests in the future if possible, once I have access to ALEXA or GOOGLE HOME.

I purchased the Nest 3rd Generation thermostat in November 2015 and it has been a game changer for me in terms of energy efficiency and cost savings. After moving into a new home and seeing my utility bills rise, I decided to make a change in 2015. I started by switching to LED light bulbs and energy-efficient appliances, but it was the Nest thermostat that really made a difference.

The installation process was surprisingly easy, despite my initial concerns. The instructions provided with the thermostat were clear, and I also found helpful videos on YouTube to guide me through the process. Before uninstalling my old thermostat, I made sure to shut off the power panel breaker to ensure my safety. I also took a picture of how the wires were connected to the old thermostat to ensure a correct installation. Testing the wires to make sure there was no power running through them was an additional precaution I took.

One of the things that attracted me to the Nest thermostat was its sleek design. I opted not to use the base-plate for a modern and clean look. The stainless steel dial is smooth and easy to navigate, and I appreciate the ability to lock the thermostat to prevent any unwanted temperature or setting changes, especially if you have children.

It took a couple of days for the Nest thermostat to learn my preferred temperature settings and when I was typically at home. After this learning period, the thermostat asked if I wanted it to automatically go into "Away Mode" when it sensed I wasn't home. I opted in for better energy savings, but you have the choice to opt out and control it manually. The smartphone application provided by Nest is free and user-friendly, allowing me to control all aspects of the thermostat remotely.

The "Far-Sight" feature of the Nest 3rd Generation is impressive. Even in the dark, it can detect motion and illuminate with the current temperature. This feature helps the thermostat determine if you are home or not and automatically switches to "Away Mode" for energy savings.

Controlling everything from the smartphone application is convenient and efficient. I can adjust the fan, cooling/heating mode, humidity level, set schedules, and view the temperature history. The Nest thermostat even reminds me when it's time to change my air filters based on the frequency of furnace usage.

Since installing the Nest thermostat, I have seen a significant drop in energy consumption, which is reflected in my gas bill. This has been consistent over the months, proving that the thermostat is indeed saving me money. In fact, my father was so impressed by the results that he also purchased a Nest thermostat and has had no complaints.

It is now February 2021, and I still own and use the Nest 3rd Generation thermostat without any issues. It has more than paid for itself in savings and I highly recommend it to anyone considering a smart thermostat. The ease of installation, sleek design, energy-saving features, and user-friendly smartphone application make it a worthwhile investment.

I recently upgraded my thermostat to this smart model, and I have been extremely pleased with its performance. The convenience of being able to control the temperature from my iPhone, even from a distance of 40 feet or from the comfort of my bed, is truly amazing. The setup process was very straightforward, even for someone like me who is not experienced with installing thermostats. The instructions provided were clear and easy to follow, making the whole process smooth.

One of the standout features of this smart thermostat is its intuitiveness. I appreciated the fact that I could easily label each cable color when replacing my old thermostat, as this new model does not require a C wire. Additionally, the thermostat responds well to voice commands from my Alexa device, and it also supports Google Assistant. The screen background changes color to indicate whether the heating or cooling mode is active, which is a helpful visual cue. The thermostat can be programmed with four comfort level modes, including Wake, Away, Home, and Sleep, all of which can be easily controlled through the accompanying smartphone app.

Another aspect that impressed me about this smart thermostat is its compatibility with a wide range of heating sources, including conventional systems, heat pumps, and gas fireplaces. It supports various heat sources such as natural gas, electric, hot water, steam, gravity, and oil. The installation process was straightforward, and I was relieved to find that I didn't need a "C" wire, as there was an unused wire in my furnace that I could connect to both the furnace and the thermostat.

The smartphone app that accompanies this thermostat is well-designed and user-friendly. Setting up the app was a breeze, and it provides a simple interface for controlling and scheduling the thermostat. My husband was able to complete the entire installation process in just 15 minutes, and we have had no issues with the device connecting to our wireless network.

I recently purchased the Heagstat thermostat and I must say, I am thoroughly impressed. As someone with 30 years of experience in HVAC, I have tried many thermostats, but this one stands out. What caught my attention first was the 24v power option at an affordable price. Unlike other overpriced options in the market, this thermostat feels solid and well-built. The buttons provide a satisfying feedback when pressed, indicating their durability.

Installation was a breeze, especially since I opted to wire it up to operate without batteries. The soft white backlight and easy-to-read display make it perfect for those with aging eyes like mine. Navigating through the menu is a breeze, thanks to its well-thought-out design. I particularly appreciate the separation of technician-level adjustments from homeowner-level adjustments, ensuring that homeowners don't accidentally tamper with settings beyond their knowledge.

I also tested the thermostat running on batteries and it functioned flawlessly. While I can't comment on battery life since I primarily rely on the 24v power option, I am impressed with the easy access panel on the front for battery replacement. No need to remove the thermostat from the sub-base like other flimsy options I've come across.

In fact, I was so impressed with this thermostat that I purchased five more to have on hand. The only improvement I can suggest is the inclusion of an hour meter, in addition to the filter hour count feature, to make it the ultimate thermostat.

Another great feature of this thermostat is its suitability for use in RVs. It can run off two AA batteries, eliminating the need for 24V A/C electricity in RVs. The inclusion of clear programming instructions and wiring diagrams makes installation a breeze, and the thermostat performs exactly as expected. The ability to control hysteresis is a great addition, allowing for precise temperature control and optimal comfort and efficiency.

In my experience, this thermostat has been accurate and reliable. I haven't had the chance to test the heat settings yet, but based on its performance during the cooling season, I have no doubts about its capabilities. It truly offers great value for the money.

Update 08/2023: The Heagstat thermostat continues to impress me. I only need to change the rechargeable batteries about every six months, which is impressive. It has proven to be a winner in terms of durability and performance.

The Nest Temperature Sensors are a game-changer when it comes to maintaining a comfortable and balanced temperature in your home. If you've been struggling with uneven temperatures in different areas of your house, this product is a must-have.

Before installing the sensors, the reviewer experienced significant temperature differences between the upstairs and downstairs of their home. The thermostat was located upstairs, causing the AC unit to constantly run to cool that area, while the downstairs remained cold. At night, the situation reversed, with the downstairs becoming hot and muggy while the upstairs stayed cool. It was later discovered that the ducts were set to prioritize cooling the upper level during the day.

However, after installing the Nest Temperature Sensors, the reviewer gained the ability to adjust the daily schedule to perfection. The sensors, in combination with the Nest thermostat, allowed them to select which sensor and temperature would drive the AC cooling. This feature alone was amazing and helped to balance the temperature throughout the day.

What truly impressed the reviewer was the added ability to control the fan in-between cooling cycles. This feature allowed air to circulate throughout the home, effectively balancing the temperature between the upper and lower levels. As a result, the temperature difference went from 3-5 degrees to a mere 0-1 degree. The reviewer cannot speak highly enough about how much they appreciate this product and how it has enhanced their home.

In terms of size, the Nest Temperature Sensors are smaller than expected, measuring around 1-1.5 inches in diameter. While some may have anticipated a larger size, it is important to note that these sensors are designed for stationary use with a Nest Thermostat/Learning Thermostat.

The pairing process is simple, thanks to the QR code battery pull tab that comes with each sensor. By scanning the QR code in the Nest app, the sensors can be easily paired with the thermostat. However, the reviewer mentioned that the directions did not mention the importance of keeping the QR code. To ensure ease of reconnection in case of device changes or router updates, the reviewer chose to cut out and tape the QR code onto the back of all three sensors. This proactive measure proved to be beneficial during a router change.

I have recently been upgrading my home to a smart house and have had my fair share of successes and failures with smart devices. However, the T9 thermostat has definitely been a success in my experience. It not only offers all the modern features you would expect from a wifi-connected device, but also some unique features that set it apart from the competition.

First and foremost, the installation process for the T9 was a breeze, and the configuration was even easier. I was pleased to find that it supports both 2.4 and 5 GHz wifi networks, providing flexibility for different setups. The display quality is excellent, and the touch screen is as user-friendly as my iPhone. Additionally, the Resideo phone app used to control the thermostat is intuitive and straightforward.

What really sets the T9 apart are the remote temperature sensors. In my home, there are two rooms that always seem to be a few degrees different from the rest of the house, especially our bedroom. By placing a T9 remote sensor in each of these rooms, I have already noticed a significant improvement in comfort. The T9 allows you to set up temperature control at the base unit or the remote sensors, giving you greater control over the temperature in your home. You can even select which sensor is used to control the thermostat, and the sensors can be configured to operate based on detecting occupancy or simply as temperature probes.

As a programmable thermostat, the T9 allows you to set desired temperatures based on the day of the week and time of the day. However, it goes a step further by enabling you to choose which temperature sensor determines the room temperature during different times of the day. For example, I have three T9 temperature sensors—one at the thermostat display and two remote sensors. On weekdays, I use the average temperature between all three sensors. At night, I rely solely on the remote sensor in our bedroom. On weekends, I only use the remote sensor in my office if someone is in that room. Otherwise, I use the average of the other two sensors. This level of customization has truly transformed the comfort of our home.

Another standout feature of the T9 is its discreet design. Unlike other modern thermostats that make a bold statement with their glossy black appearance and large size, the T9 blends seamlessly into the background of the wall. This was exactly what I wanted from a thermostat, as I prefer it to be unobtrusive and not draw unnecessary attention.

Before purchasing the T9, it's worth considering the need for a "C-wire" and the possibility of wall painting when replacing an older thermostat, as other reviews have pointed out. However, if you have rooms in your house that experience varying temperatures, the T9 with its optional remote sensors is an excellent choice.

Lastly, the remote sensors attach to the wall using 3M Command strips (provided with the device). They are battery-operated and claim to have over a year of battery life on AAA batteries. The sensors connect to the main unit using a proprietary wireless connection.
