Sinope TH1123WF Smart Wi-Fi Thermostat - 2021 Reviews

We’ve looked at a lot of low voltage thermostats for gas and oil heating systems, but Sinope TH1123WF ($ 114.95) is a smart line voltage thermostat exclusively for electric heating systems. Allows you to control the heating of your home using your phone or voice with Alexa, Google Assistant or Siri voice commands. It integrates seamlessly with Apple HomeKit and SmartThings home automation ecosystems, is relatively easy to install (although you have to work a little with wiring), and generates power and cost-per-kWh reports. It’s a great choice if you’re heating your home with electric baseboards, but if you have a regular gas or oil heating system, check out Editors’ Choice winner for smart thermostats, Nest Thermostat ($ 129.99) instead.

Lots of smart integrations

TH1123WF is compatible with short-cycle heating plinths, short-cycle convector heaters, forced-cycle convector heaters with long-cycle fan and radiant ceiling heaters. It has a maximum load (resistive) of 3,000 watts at 240VAC, with a temperature reference point range from 41 degrees (F) to 86 degrees (F). If your electric heating system consumes more than 3,000 watts, the Sinope TH1124WF ($ 129.95) offers a maximum load of 4,000 watts.

The white housing of the thermostat measures 5.0 by 3.4 by 1.0 inches (HWD) and has a 2-inch LCD on the right side that displays the ambient temperature of the room, the reference and outdoor temperature, the current time and the power of the Wi-Fi signal. Be. Below the display are the up and down buttons for setting the temperature. On the left, a removable panel hides the mounting holes. The back of the thermostat has two wires for connecting the thermostat to the electrical junction box of your heater. Use a 2.4 GHz Wi-Fi radio to connect to your home network.

TH1123WF responds to Alexa, Google Assistant and Siri voice commands, plus it works perfectly with HomeKit and SmartThings home automation systems. It also supports geofencing; the thermostat can use the phone’s location to switch between Home and Abs.

Application options

The thermostat uses the mobile application Neviweb from Sinope (available for Android and iOS). Other Sinope smart devices, including lights, water protection products and smart sockets, work with the same app. The home screen of the application shows the current status of your home (Home or Gone) and the local outdoor temperature. This section also features buttons for activating Saved Scenes and a Consumption History button; touch the latter to see diagrams of energy consumption in kWh or by cost per kWh. Use the Geofencing button to enable geofencing, set a perimeter, and assign a tracking device. The Connected Platforms button provides information for connecting the thermostat to Alexa, Google, HomeKit and SmartThings accounts.

At the bottom of the screen are the Home, Devices, and Scenes icons, as well as a three-bar icon. Touching the Home icon takes you back to the home screen. Touching the Scene icon allows you to create easily accessible presets (Scene). For example, you can set the thermostat so that the temperature changes when you touch the Scene button or when you use Alexa, Google, or Siri voice commands to turn on the Scene.

Select the three-bar icon to edit your account settings, add locations, and define geofencing parameters. The Devices icon opens a screen that displays parts for all your Sinope devices, by room or type. Touch the thermostat tile to make manual changes to the device or to implement a program. This screen displays current and reference point temperatures; it has up and down arrows to adjust the temperature. Here you can also rename the device, set the time and temperature format, and change the Away reference point. Details on Consumption History are also available here. Finally, the Schedule button allows you to create custom heating schedules for each day of the week.

Requires some wire work

As with most smart thermostats, the TH1123WF is fairly easy to install. However, use the cables from the heating system power supply instead of the low voltage thermostat cables. You can usually find the wires in question in an electrical junction box that is attached to the heating system or nearby in a power switch. If you do not feel comfortable working with electrical wiring, you should hire a professional to do the physical installation.

Start by turning off the heating system circuit breaker on the main electrical panel. Then remove the thermostat cover and plate from the front of the junction box that provides power to the system. If you see two wires (black and white) on the junction box, connect one of the thermostat wires to the black wire and the other to the white wire and secure them with the included nuts. If there are four wires in the box (two black and two white), connect the two white wires and then connect one thermostat wire to each of the black wires. Attach the thermostat to the junction box using the included screws and reattach the cover before restoring power to the circuit.

After installing the thermostat, download the Neviweb app and create an account. The application asks you for the name of the house, the postal code and the cost of electricity in kWh-percent (from the utility bill). To add the home thermostat, tap the three-bar icon in the lower-right corner of the My Home section, then choose Add Device. Select TH123WF from the list of Wi-Fi thermostats, make sure the thermostat has power, and tap Next. Press both thermostat buttons at the same time to activate the configuration mode; when the Wi-Fi icon appears on the screen, tap Next to search for the device. Allow the thermostat to join your home, select the Wi-Fi SSID when the list appears, and enter your Wi-Fi password. After a few seconds, TH1123WF will join your network. Tap Finish to complete the installation.

To add the thermostat to the HomeKit, open the Home app on your phone, tap the plus icon in the upper right corner, and select Add accessory. Use your phone to scan the HomeKit code on the side of the thermostat, tap Add to Home, give the device a name, and add it to any room to complete the pairing.

TH1123WF did an excellent job controlling the heating of the electric baseboard in our tests. Responds quickly to application commands to reset heat points and put the system in Standby mode; he also followed my schedule to a tee. Alexa and Siri’s voice commands to change the reference point’s temperature worked as intended, as did a HomeKit automation to set the heat to 70 degrees Fahrenheit when an Eve room detected motion.

An affordable option for electric heating systems

The reasonably priced Sinope TH1123WF Smart Wi-Fi Thermostat ($ 144.95) is an excellent choice for controlling the electric heating system. It offers a lot of features, including built-in Wi-Fi; Alexa, Google Assistant and Siri voice support; HomeKit and SmartThings integrations for home automation; and geofencing location control. It can also tell you how much energy you use to heat your home and how much it costs. However, the TH1123WF does not work with low voltage systems powered by gas and oil. If you need a thermostat, consider Nest Thermostat, which is just as affordable, easy to install, and works with Alexa and Google voice assistants.
