Our verdict on each
Lennox
Lennox suits households that want heating and cooling handled locally, without a hub or a running fee, and pairs that with 10 years of warranty. The catch is reach: sales cover US and CA only, and the catalogue stays on thermostat and sensor with nothing else to add.
Shelly
Shelly suits homeowners and renters who want broad smart home kit with no hub to buy first. Device prices start at €12.90, the range covers thermostat, lighting, plug, hub, sensor and blinds work over matter, zigbee and z wave, and local control keeps routines running when the internet drops.

Pros and cons
Lennox
Pros
- No hub is required and local control is supported, so schedules and set points stay on the thermostat itself.
- The subscription is $0 a month, so there is no renewal to budget for after the purchase.
- Heat pump compatibility and energy reporting are both listed, covering the two checks most households make on a thermostat.
Cons
- Matter certified is listed as no, so wi fi and matter pairs a protocol with a standard the thermostat is not certified to.
- Support runs on email, chat and help centre only, and phone is not among the listed channels.
- The range is sold in US and CA only, so buyers in other markets need a different supplier.
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
Lennox
Who it suits
- Households in US and CA running a heat pump who want a thermostat that works without a hub and keeps control on the device.
- Renters and homeowners who would rather see no recurring fee, since the monthly subscription is $0.
- Buyers who rate a 10 years warranty and a long trading history above a wide device catalogue.
Who should look elsewhere
- Aqara buyers who want the line to stretch past thermostat and sensor into hubs, lighting, plugs and blinds.
- Lutron buyers who want climate control in the same system as lighting and blinds, since Lutron lists lighting, blinds and thermostat.
- SONOFF buyers who want radiator valves and hubs, since thermostat, trv and lighting reaches well past the thermostat and sensor on offer here.
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
Lennox
What does a Lennox thermostat cost once you have bought it?+
The recurring part is simple: the monthly subscription is $0, so there is nothing to renew and no fee to set aside each month. You pay for the hardware, and 10 years of warranty means there is no extra cover to buy. Running cost stays at nothing.
Do I need to buy a hub or a bridge first?+
No hub is required. The thermostat and sensor run on wi fi and matter, and local control is supported, so schedules and set points live on the device. There is no extra box to mount, power or pair, and nothing sitting between the thermostat and your router to keep running.
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.
