The major smart thermostats (ecobee, Nest, Mysa, Sinopé) do not require a monthly subscription for their core features. Scheduling, app control, remote access, energy reports, and smart home integration all come included.

A few premium features on specific platforms do require a subscription or have changed their policies. This page covers what’s free and what costs extra on each platform.

What You Always Get Without a Subscription

On every major smart thermostat:
– Wi-Fi app control (iOS and Android)
– Scheduling (weekly schedules with per-day customization)
– Remote temperature access
– Basic energy usage tracking
– Smart home integration (Alexa, Google Home; HomeKit on ecobee)
– Software updates
– Demand-response program participation (where available)

ecobee: No Subscription Required

ecobee’s full feature set is included at no ongoing cost:
– eco+ optimization
– Room sensor integration (sensors sold separately, but no subscription to use them)
– Demand-response enrollment
– Detailed energy reports
– HomeKit, Alexa, Google Home integration

ecobee Premium: The hardware price includes the air quality monitor feature and built-in speaker/mic. No subscription, no ongoing fees.

ecobee’s no-subscription stance has been a differentiator from Nest’s evolving model. All features remain free as of mid-2026. Check ecobee’s current terms, since policies can change.

Google Nest: What’s Free vs What Costs Extra

Free with any Nest thermostat:
– App control
– Scheduling
– Temperature history (90 days)
– Energy history (12 months)
– Home/away assist
– Alexa, Google Home integration

Nest Aware (subscription, optional): Nest Aware applies to Nest cameras and doorbells. The thermostat’s core features don’t require it. As of mid-2026, the thermostat has not required a subscription for its core functions.

Rush Hour Rewards: Demand-response enrollment through Google is free.

Google Home ecosystem: The Google Home app is free; smart home integrations within it are free.

Mysa: No Subscription

Mysa has maintained a no-subscription model since launch. All features (scheduling, geofencing, energy reporting, freeze protection, HomeKit, multi-zone dashboard) are included with the device purchase. No ongoing fees.

Sinopé / Neviweb: No Subscription

Sinopé’s Neviweb platform is free to use. All thermostat features, group scheduling, energy reports, and Hilo integration are included without a subscription. The Hilo app (Hydro-Québec) is also free.

Honeywell Home: Currently Free, Verify

Honeywell’s T9, T10, and Sensi thermostats have operated without mandatory subscriptions. Verify at time of purchase, since Resideo/Honeywell has explored subscription models for some features in their broader product line.

What “No Subscription” Thermostat Actually Means

None of these thermostats can avoid the cost of cloud infrastructure. They’re all cloud-dependent for app control, remote access, and optimization. The business models:

  • ecobee: Hardware margin funds the cloud service
  • Nest / Google: Ecosystem integration (you’re in the Google world) funds the service
  • Mysa / Sinopé: Hardware margin; both are smaller companies where cloud costs are proportional

If any company changes its model, industry practice suggests 30-90 days notice before features require payment. None of the major brands have done this as of mid-2026, but it’s worth reading the app’s terms of service once a year.
