Honeywell Home is a thermostat and comfort brand sold by Resideo, the US company that Honeywell spun off in 2018 and that uses the Honeywell Home name under a long-term licence. It covers T-series and Lyric thermostats, the evohome zoning system in Europe, water leak detectors and related sensors. Which app and which cloud applies depends on the product and the region.
Most connected Honeywell Home products work through Resideo's cloud and a phone app. Wi-Fi thermostats such as the T9 and the newer X2S and X8S use Wi-Fi, the T6 Pro has a Z-Wave version for hubs, and the X2S and X8S add Matter. Several apps share the brand: Resideo Smart Home (formerly called Honeywell Home), First Alert by Resideo for newer models, Total Connect Comfort for older US models, and Total Connect Comfort International for evohome in Europe.
That suits people who want a mainstream thermostat that links to Alexa, Google, Apple Home and SmartThings, or who want evohome multi-zone heating in Europe. It is weaker for local control: Home Assistant and openHAB integrations run through the cloud, some need a separate developer account, and the right app for a given model is confusing because of the regional and product-line splits.

The main app for many Honeywell Home thermostats, formerly called Honeywell Home. Its listing covers schedules and temperature control, geofencing, HomeKit connectivity, energy programs including Canadian demand response, water leak detectors and installer tools. Resideo's UK page ties it to the T6R-HW thermostat, a leak detector and L5 WiFi actuators. L-Series customers are directed to the First Alert app. Published by Resideo Technologies.
Resideo's newer connected-home app. Its listing covers select Honeywell Home smart thermostats, cameras and video doorbells, smoke and CO alarms, leak detectors, locks and security panels. Honeywell Home's X2S and X8S guides use it for setup. The listing says it was formerly called the First Alert app. We could not confirm a Google Play link.
Remote control for older US Wi-Fi thermostats. Resideo's page lists the WiFi Smart Color Thermostat (RTH9585WF) and the VisionPRO 8000 WiFi thermostat, with schedules, humidity control, energy reports and alerts.
The app for evohome in Europe and related systems: evohome zoning, a single-zone thermostat with an internet gateway, a European voice-controlled thermostat, and evohome Security and SucreBox Security. Resideo's UK page lists it for evohome packs. The App Store listing does not name Round or T-series products.
An installer app for professional setup of Resideo products. The T6 Pro Z-Wave page says it currently supports T5 and T6 thermostats, and it needs a Resideo One account.

Resideo lists WiFi thermostats in its US Total Connect Comfort app. The X2S is reported to work on 2.4 GHz and 5 GHz, and the X8S supports dual-band Wi-Fi. Honeywell Home thermostats connect through Resideo's cloud.
The T6 Pro Z-Wave thermostat works with Z-Wave and Z-Wave Plus gateways, hubs and controllers, with Z-Wave 5.0 chipset encryption and extended range. Its page names only the Resideo Pro app and does not describe a homeowner app or other platforms.
evohome is controlled through the Total Connect Comfort International app and Resideo's EMEA pages. The pages we read do not state the radio used between the controller and zone devices, so we could not confirm it. The Homey listing marks both its evohome device types as needing a Homey Bridge.
The Honeywell Home X2S (announced at CES 2025, $80, US and Canada) and the X8S ($219.99) are described as Matter-compatible and work with Alexa, Google Home and Apple Home. Neither article says which Matter version it supports. Older T-series, evohome and Lyric thermostats are not listed with Matter in the sources we read.
Resideo's partner page lists Alexa for the T10+ Pro, X2S, T9, T5, T6 Pro and 9000 thermostats, the PROA7PLUS panel and a Fresh Air Ventilation Kit. Support varies by model and region, and the page also lists discontinued products.
Resideo lists Apple Home for the T9, T10+ Pro and T6 Pro. HomeKit support reached the T9 in a November 2021 update. Reviewers of the Resideo app report syncing problems after updates. Resideo's UK page also lists Apple Home for the T6R.
Resideo's partner page lists SmartThings for the T5, T9, T10+ Pro, T6 Pro, 9000 and VisionPRO 8000 with RedLINK, among others. Resideo's evohome Homey announcement also says evohome works with SmartThings.
IFTTT lists a Honeywell Home service (honeywell_lyric). Triggers cover camera motion, security modes and water leaks. Actions include setting a thermostat setpoint or fan mode, room priority on T9 and T10 models, and Z-Wave lights. We could not confirm who maintains the service.
Resideo's brand list includes Control4, and a planned Snap One acquisition was announced in 2024. We could not confirm a Honeywell Home thermostat driver or how Control4 connects to these products.
Built-in integrations that Resideo does not maintain, each cloud polling. Honeywell Total Connect Comfort (US) is maintained by a contributor and says the TCC service can be unstable. Honeywell Lyric needs a Honeywell developer account and app credentials, covers T9 and T10 room priority and room sensors, and is separate from the Resideo account. Honeywell Total Connect Comfort (Europe) covers evohome and the Round thermostat but is a legacy integration with read-only schedules and no cooling.
Resideo is listed as the developer of the Honeywell Home evohome app, which covers the evohome Wi-Fi thermostat and controller (up to 12 zones). The store page lists Homey Cloud, Pro, Pro mini and Self-Hosted Server, but marks both device types as Homey Bridge required with Cloud technology. Resideo's 2023 announcement says it works with Homey Cloud and Homey Pro without mentioning a bridge, so the requirement is unresolved. US T-series thermostats are not covered by this app.
A beta Resideo API binding by an independent author is shared on the openHAB community forum and is not an official add-on. It targets Lyric Round and T5, T6, T9 and T10 thermostats and needs Honeywell developer API credentials. Thermostats on the First Alert or Total Connect 2.0 systems were reported not to work.
A community Homebridge plugin brings Resideo T5, T6, T9, T10 and Round thermostats and a leak detector into HomeKit. It needs a Resideo developer account created at the Honeywell Home developer site. Some Total Comfort Control thermostats may not accept commands.
We searched for a Hubitat driver or app for Honeywell Home thermostats and found none we could verify. The T6 Pro Z-Wave thermostat is a generic Z-Wave device, but its Resideo page names no hubs.
Honeywell Home's developer portal documents APIs for thermostats (setpoints, mode, holds, schedules, fan, and room priority on T9 and T10), shutoff valves, domestic hot water, cameras, leak detectors and security systems. It lists two API hostnames, and the integrations above rely on it. Authentication details were not visible on the page we read.
Checked 11 November 2026 against the brand's own pages, app store listings and each project's own page. “Not found” means we searched and found nothing, not that it is impossible. Compatibility changes often. Spot an error? Tell us and we will fix it.
