After Checkout: What ecobee’s Smart Thermostat Premium Bills You For, and Why the Aqara Hub M3 Bills You Nothing

A thermostat and a hub are not alternatives. What they share is the question of what arrives on your bill after the box is open, and only one of them keeps sending one.

A thermostat and a smart home hub are not alternatives, and nobody stands in a shop deciding between them. The two do share one question worth asking before any smart home purchase: what does this cost after checkout? ecobee sells a $229.99 thermostat attached to a security subscription that changed shape in 2026, with a deadline attached to it. Aqara sells a hub with no subscription at all. That sounds like the simpler deal, and in one important respect it is not.

Key figures, 1 September 2026

• ecobee Smart Thermostat Premium: $229.99 on ecobee’s own store, marked down from a shown $259.99
• Launch MSRP in May 2022 was $249.99, so the list price has climbed $10 since
• ecobee Smart Security Core tier: free, and keeps no video history whatsoever
• Existing ecobee subscribers keep their current plan only until 31 December 2026
• Aqara Hub M3: no subscription offered; $129.99 on its product page and $159.99 on Aqara’s hub collection page, same day

The thermostat is the small number

ecobee’s own store shows the Smart Thermostat Premium at $229.99 on 1 September 2026, discounted from a displayed $259.99, in stock with free shipping and a three to seven business day delivery window. The company announced it on 17 May 2022 at $249.99. Four years on, the list price is $10 higher than launch while the everyday selling price sits below it, which is a marketing structure rather than a discount.

That is the entire hardware cost, and for a household that only wants heating and cooling control it is also the final cost. ecobee does not put subscription pricing on the Premium product page, and nothing about scheduling or temperature control is gated. The bill only starts if you buy into the part of the product that ecobee has been quietly restructuring.

What the security tiers cost in a year

ecobee’s own plans page sets out three levels. Core costs nothing. Plus is $5 a month or $50 a year and adds package detection on one camera, 30 days of event history on one camera, smoke alarm listening and enhanced energy savings. Advanced is $10 a month or $100 a year for the same features across unlimited cameras. Two add-ons sit on top: Smoke Alarm Detection at $5 a month or $50 a year, and Total Protection at $10 a month or $100 a year. A one month trial comes with eligible device setup.

Do the arithmetic before you commit. Advanced with Total Protection added runs to $200 a year, which is within $30 of the thermostat itself. Over three years the recurring cost is roughly two and a half times the hardware. That is not an argument against subscribing; it is an argument for pricing the tier you actually want rather than the one on the shelf card.

Core is free, and it stores nothing

The free tier is more capable than free tiers usually are, and it has one hole in the middle of it.

• Motion and person detection
• Door and window open and close alerts
• Two way talk
• Live view on the Smart Thermostat Premium itself
• A manually triggered siren

The monitoring ecobee moved after people had already bought in

What Core does not give you is any video or event history at all. Nothing is retained. Live view is live only, so if you were not watching, there is nothing to go back to. Every version of history costs money, starting at $50 a year for one camera.

The subscription also changed underneath existing owners. Tom’s Guide reported that ecobee took 24/7 professional monitoring out of its top tier plan and put it behind a second paywall at an extra $10 a month, moving full protection from $10 a month to $20; smoke monitoring became a further $5. Existing customers keep their current plans only until 31 December 2026, after which they move to the new structure.

That is the fact to weigh, more than any feature list. The price a buyer agrees to at the till is a starting position, and in this category it moves in one direction.

No monthly fee is not the same as no dependency

The Aqara Hub M3 charges nothing, ever. No subscription appears anywhere on its product page. The hardware is generous for the money: Power over Ethernet and USB-C, 8GB of encrypted local storage, dual band Wi-Fi with WPA3, a 360 degree learning infrared blaster, a 95 decibel speaker, and deliberately no microphone and no camera. Aqara markets it as an Edge Hub that prioritises local control and automation.

PCWorld tested that claim by unplugging the modem, and reported that attempts to control devices invariably timed out until the internet connection was restored. The reviewer also could not activate the device binding automations that are supposed to run offline. A hub with no monthly fee that stops responding when the broadband drops has simply moved the cost from your card to your evening.

There is a second thing to check before ordering. Aqara’s own store showed the M3 at $129.99 on its product page on 1 September 2026, a page that simultaneously rendered both ‘Only 0 left in stock’ and ‘Item is out of stock’, while Aqara’s hub collection page listed the same product In Stock at $159.99 the same day. Two prices, two stock states, one shop. Confirm which one you are being charged.

ecobee has switched a thermostat’s servers off before

On 31 July 2024 ecobee ended cloud support for its original 2007 Smart Thermostat and the EMS line, having announced it on 3 May 2024. T3 reported the roughly three months of notice and the 30 percent discount code offered as compensation. Heating and cooling control and scheduling kept working; weather, smart home integrations and anything that depended on a server did not. That is the company’s own record on support lifetime, and it is a reasonable thing to price into a 2026 purchase.

Ownership matters here too. ecobee has been a subsidiary of Generac Holdings since a $770 million acquisition announced on 1 November 2021, and ecobee by Generac integrations now appear on the product page. Meanwhile neither Matter nor Thread is mentioned anywhere on the Premium’s specification, four years after Matter shipped. On a flagship in 2026 that is a decision, not a gap in the datasheet.

The honest split is this. If you want a thermostat and will never buy an ecobee camera, the subscription is irrelevant to you and the Premium is a competent piece of hardware at $229.99. If the security stack is why you are interested, price three years of the tier you actually want, note the 31 December 2026 changeover, and decide with that number in front of you. And treat the M3’s zero for what it is: real money saved, attached to a local control claim its own reviewers could not reproduce.
