Pros and cons
ecobee
Pros
- Entry pricing from $139.99 sits close to the site entry median of €127.49, so heating control is not a premium bet.
- No hub is required, so there is no extra box to buy, and energy reporting comes with the smart thermostats.
- The thermostat warranty runs 3 years, with a 30 day money back period behind the purchase.
Cons
- The security side is a running cost: the paid plan is $5 a month, and professional monitoring only sits on that tier.
- The video doorbell is wired, so it needs a cable run at the front door rather than a battery you swap yourself.
- Recorded video is kept for 30 days, a short window for reviewing anything older.
Shelly
Pros
- A hub is not required, so plugs, sensors and switches start working without bridge hardware.
- Local control is supported and energy reporting comes as standard, so offline routines and consumption figures arrive together.
- Entry price €12.90 sits below the €15.36 median for smart thermostat brands.
Cons
- Camera video tops out at 1080p, below the higher resolutions common on other security cameras.
- Cloud retention of 30 days needs the Shelly Smart Control premium plan at €3.99 a month.
- The camera runs on battery and wired, so placement decides between wiring and battery changes.
Who each suits
ecobee
Who it suits
- Buyers who want a thermostat as the anchor and a camera, video doorbell or alarm sensor added to the same brand later.
- Homes that already run alexa, google and homekit and want heating data in the same place as everything else.
- People who want professional monitoring without a long agreement, since the contract length is 0 months.
Who should look elsewhere
- Full home device shoppers, since Aqara's range covers hub, sensor and lighting while ecobee's device types are thermostat and sensor.
- Buyers chasing lighting and blinds control as the main event: Lutron's device list runs lighting, blinds and thermostat, well beyond a heating brand.
- Budget builders who want a hub, heating valve and blinds under one roof, which is what SONOFF lists in thermostat, trv and lighting.
Shelly
Who it suits
- Renters and new buyers who want a hub-free start and automations that keep working offline.
- Households already running Alexa, Google or HomeKit, or planning to settle on Matter later.
- Anyone tracking energy use, since energy reporting is standard across the range.
Who should look elsewhere
- SONOFF, if you want thermostatic radiator valves, since thermostat, trv and lighting includes trv and the Shelly range leaves it out.
- Aqara or Lutron, if the same device mix suits you better from another brand, since hub, sensor and lighting and lighting, blinds and thermostat cover the same categories.

Questions about each
ecobee
How much does it cost to get started with ecobee?+
Hardware starts at $139.99, which puts ecobee close to the site entry median of €127.49. That covers the equipment. Anything on the security side, monitoring included, is billed separately each month. A 30 day money back period covers the hardware purchase if the fit turns out wrong.
Do I have to pay a subscription to use the security devices?+
There is a free Core plan that covers motion and person detection along with door or window open and close alerts, so the basics cost nothing to run. Paying $5 a month moves you onto the plan that adds professional monitoring and stored video history. The choice is how much of the security side you want switched on.
Shelly
What does Shelly hardware cost to start with?+
Entry price is €12.90, which covers the cheapest device in the range rather than a bundle. The camera sits higher at €39.90, and the catalogue spans camera and smart lock. Budget for hardware first, then decide whether the cloud extras earn their monthly fee.
Is there a monthly fee or a contract?+
The Shelly Smart Control premium plan costs €3.99 a month, and it is optional rather than required. There is no minimum term, since the contract length is 0 months. The Shelly Smart Control standard plan keeps live streaming, motion event recordings and smart notifications at no cost.
