Best Smart Thermostat for a Holiday Let Between Guests
A holiday let needs a thermostat that can be reset from a phone, not a dial a cleaner has to remember. The picks below suit three kinds of owner: the remote host who manages the property from another town, the hands-on owner who wants a simple DIY install, and the budget-conscious host fitting several units at once. Every option here connects to Wi-Fi and works with a voice assistant, so a guest can adjust the temperature without a manual. The overview table below sorts all five by key spec and price tier, and each review explains who the pick is not for.
Overview Of The Picks
| Product | Key Spec | Best Use | Price Tier |
|---|---|---|---|
| Honeywell Home RTH9585WF1004 | 7-day programmable color touchscreen | Hosts who want a familiar brand and an on-wall display | Mid |
| Sensi Smart Thermostat ST55 | DIY Wi-Fi install, Energy Star | Simple retrofit in an older let | Budget |
| ecobee Smart Thermostat Essential | Siri, Alexa and Google Assistant | Mixed-guest households with Apple devices | Budget |
| ecobee Smart Thermostat Enhanced | Energy Star, three-assistant support | Hosts wanting ecobee features at a lower tier | Mid |
| Amazon Smart Thermostat | Works with Alexa and Ring | Alexa-first hosts managing several units | Budget |
Honeywell Home RTH9585WF1004 Wi-Fi Smart Color Thermostat
Type: Wi-Fi smart thermostat
Display: Color touchscreen
Programming: 7-day
Certification: Energy Star
Voice: Alexa ready
Finish: Gray
The Honeywell Home RTH9585WF1004 is the pick for hosts who want a thermostat that looks like a fixture rather than a gadget. The color touchscreen gives guests a clear on-wall interface, and the seven-day programming lets an owner set a different schedule for changeover days and quiet days. Alexa readiness means voice control without a hub, and the Energy Star listing signals efficiency claims the buyer can check on the label.
This model earns its place because it is the most conventional of the five: a recognizable brand, a physical screen, and a schedule that can be edited on the wall or from the app. It suits the host who wants guests to see a familiar name and a visible display. The trade-off is that a full color touchscreen draws more attention and power than a plain unit, and a mid-tier price makes it a bigger outlay per property than the budget picks.

Sensi Smart Thermostat ST55
Type: Wi-Fi smart thermostat
Install: DIY
Certification: Energy Star
Voice: Alexa
Model: ST55
The Sensi ST55 is built around easy self-install, which matters when a host is fitting a thermostat in a let between bookings rather than paying a contractor. Wi-Fi pairing and Alexa support cover the essentials, and Energy Star certification keeps the efficiency story simple for guests who ask. The design is plain and function-first, which suits a rental where the hardware should not invite fiddling.
It suits the hands-on owner with basic wiring knowledge who wants a no-fuss retrofit in an older property. Its place in the list is the value pick for hosts who do not need a color screen or a wall display. The trade-off is that the simpler interface offers less on-screen guidance for guests, so a short welcome note on how to adjust the temperature is worth adding.

ecobee Smart Thermostat Essential
Type: Programmable Wi-Fi thermostat
Voice: Siri, Alexa, Google Assistant
Certification: Energy Star
Line: ecobee Essential
The ecobee Smart Thermostat Essential covers the three major voice assistants, which is the practical choice for a let that attracts guests with mixed phones. Siri, Alexa and Google Assistant support means an iPhone household and an Android household can both control the heating without downloading anything new. Energy Star certification and programmable scheduling round out the core feature set at the entry tier of the ecobee range.
It earns its place as the pick for Apple-heavy guest lists, where Siri control is the deciding factor. The Essential line trims the extras that sit higher up the range, so hosts who want those features should look at the Enhanced model below. The trade-off is that the entry tier strips back the sensor and accessory ecosystem, so a host planning a larger multi-room setup may outgrow it.

ecobee Smart Thermostat Enhanced
Type: Programmable Wi-Fi thermostat
Voice: Siri, Alexa, Google Assistant
Certification: Energy Star
Line: ecobee Enhanced
Use: Smart home
The ecobee Smart Thermostat Enhanced sits a step above the Essential and keeps the same three-assistant support, so Siri, Alexa and Google Assistant all work out of the box. Energy Star certification and programmable Wi-Fi scheduling make it a straightforward fit for a let where the owner wants efficiency without a premium price. The smart-home integration is the headline: it slots into a broader connected setup rather than standing alone.
This is the pick for a host who already runs a smart-home system and wants the thermostat to talk to it. It earns its place as the mid-tier ecobee that adds capability over the Essential without jumping to the top of the range. The trade-off is that the extra smart-home features are only worth paying for if the rest of the property is already connected, so a basic let may not see the benefit.

Amazon Smart Thermostat
Type: Smart thermostat
Voice: Alexa
Integration: Ring
Focus: Energy saving
The Amazon Smart Thermostat is the budget-first option and the most popular of the five, which fits its role as the easy bulk buy for a host with several units. It works with Alexa and Ring, so an owner already using Amazon devices can manage heating alongside doorbells and cameras from one app. The energy-saving focus keeps the pitch simple for guests and for the owner’s running costs.
It earns its place as the pick for Alexa-first hosts who want the lowest outlay per property. The trade-off is that the ecosystem is narrower than the ecobee models: there is no Siri or Google Assistant support, so an Apple or Google household gets less from it, and the feature set is deliberately lean.

- Guest simplicity: A clear on-wall display or a short welcome note reduces calls about how to change the temperature.
- Remote control: Confirm the app allows schedule changes from another location, which is the core need between guests.

- Price tier: Budget picks suit multiple units; mid-tier picks add displays and smart-home integration for a single flagship let.
- Scheduling: Seven-day programming lets changeover days run on a different schedule from quiet days.
