As an Amazon Associate we earn from qualifying purchases. Links on this page are affiliate links.
The Honeywell Home X8S Smart Thermostat with Sensor targets complex HVAC setups and offers unique doorbell integration. If you are searching for honeywell home x8s smart thermostat alternatives, you may need a different size, feature set, or brand. This original model features a large 5-inch display and supports up to 3 heat/2 cool heat pump systems. It also includes Matter certification and compatibility with Apple Home, Google Assistant, and Alexa. Its wireless room sensor extends range up to 200 feet for precise comfort control.
You might prefer a compact design, a lower price point, or support for radiant floor heating instead. The alternatives on this list were chosen because their specifications overlap with the original. We reviewed options like the Ecobee Smart Thermostat Premium for whole-home sensor zoning and MAXKOSKO thermostats for multi-zone radiant floors. Each product meets specific needs that the X8S may not address, such as simpler wiring requirements or dedicated floor heating control. This guide helps you compare these specs to find the right fit for your home.
How each alternative compares
Ecobee Smart Thermostat Premium with SmartSensor
The Ecobee Smart Thermostat Premium replaces the X8S’s 5-inch display with a smaller 4.09-inch interface. It focuses on whole-home comfort by including a SmartSensor for room-level temperature tracking. Unlike the X8S, which prioritizes doorbell camera integration, the Ecobee emphasizes air quality monitoring and voice assistant compatibility. You get precise zoning without the bulk of the larger screen. This model suits users who value detailed sensor data and air quality insights over visual customization or intercom features. It offers robust HVAC compatibility similar to the X8S but trades the large touchscreen for focused environmental control and multi-room presence detection.
MAXKOSKO 4-Pack Electric Floor Heating Thermostat
The MAXKOSKO 4-Pack Thermostat serves a different purpose than the X8S by targeting radiant floor heating zones. It lacks the X8S’s complex HVAC support for heat pumps and conventional forced air systems. Instead, it offers multi-zone control for electric radiant floors with 120V or 240V support. The touchscreen interface provides basic programmability and Wi-Fi connectivity. You choose this if your primary need is managing floor heating across multiple rooms rather than whole-home climate control for standard HVAC systems. It gives up doorbell integration and advanced air quality features for specialized radiant zone management and voice assistant support.
YeloDeer 4-Pack Dual-Voltage Radiant Floor Thermostat
The YeloDeer 4-Pack Thermostat focuses on multi-room electric radiant floor heating. It differs from the X8S by supporting dual-voltage systems for various floor heating setups. The X8S handles complex heat pump and conventional systems, while the YeloDeer unit is specialized for radiant zones. You get flexible voltage support and voice control for managing heat across several floors. This option sacrifices the X8S’s large display, doorbell intercom, and air quality monitoring. It is best for users who need to control multiple radiant heating zones independently rather than managing a central HVAC system with advanced smart home integrations.
Honeywell Home Smart Color Touchscreen Thermostat
The Honeywell Home RTH9600WF Color Touchscreen Thermostat offers a smaller 4.5-inch display compared to the X8S’s 5-inch screen. It requires a C-wire like the X8S and supports forced air and heat pump systems. This model provides detailed weather and humidity data on a customizable screen. You gain Energy Star certification and programmable features without the doorbell camera integration found on the X8S. It is a solid choice for homes with existing C-wires that prioritize weather data and standard smart home compatibility over advanced sensor-based zoning or intercom functionality. It simplifies control while maintaining essential HVAC management capabilities.
Google Nest Smart Wi-Fi Thermostat
The Google Nest Smart Wi-Fi Thermostat features a compact 3.31-inch design, significantly smaller than the X8S’s 5-inch display. It prioritizes energy monitoring and remote control via the Google ecosystem. Unlike the X8S, it lacks doorbell integration and advanced air quality tracking. You get programmable features and Wi-Fi connectivity for homes where app control is key. This model suits users invested in Google Assistant who want energy-saving insights without the bulk of a larger screen. It gives up the X8S’s sensor-based comfort targeting and complex HVAC compatibility for streamlined energy management and ecosystem integration.
Google Nest Programmable Wi-Fi Thermostat (Renewed)
The Google Nest Programmable Wi-Fi Thermostat (Renewed) offers a compact 3.31-inch design without requiring a C-wire. It differs from the X8S by omitting the large display and doorbell integration. You get app-controlled climate management and support for Google Assistant and Alexa. This model is ideal for users seeking a simpler, smaller thermostat for standard HVAC systems. It sacrifices the X8S’s advanced occupancy detection, air quality monitoring, and complex system compatibility. It provides basic programmable features and Wi-Fi connectivity for those who prioritize ease of use and compact size over advanced smart home sensors and visual customization.
