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.
Vivint
Vivint suits households that want a monitored system sold, installed and maintained as a single package rather than a box of self installed cameras. It scores 8.8 overall, and the trade to weigh is a higher entry price and a contract term against professional monitoring on every device.

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.
Vivint
Pros
- Professional monitoring is included rather than sold as an add on, and the plan also supports local storage with video kept for 10 days.
- A single plan spans alarm, camera and smart lock, so cameras, a video doorbell, a smart lock, an alarm and a smoke alarm run on the same account.
- The recurring fee of $24.99 to $44.99 places Vivint at 46 of 51 on monthly cost, which reads well for a monitored service.
Cons
- The entry figure of $199.99 ranks 65 of 70, far above the $19.99 Annke charges and the $13.95 The Home Security Superstore charges for a single device.
- Contract terms run 0 to 60 months, so the $24.99 to $44.99 monitoring fee keeps going well past the point where a cheaper kit would have paid for itself.
- The service sells in the US only, which closes it off for buyers in other countries.
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.
Vivint
Who it suits
- Households that want professional monitoring and installation handled rather than self installed.
- People fitting out a whole home at once, since one account covers alarm, camera and smart lock.
- Owners who already run Google in the home, as the range works with google.
Who should look elsewhere
- Buyers outside the US, where the service is not offered.
- Shoppers on a tight entry budget, since Annke at $19.99 and Aqara at £36.98 both start lower than $199.99.
- Renters who may move during the term, because contract terms run 0 to 60 months.

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.
Vivint
What does a Vivint system cost to begin with?+
The introductory figure for the Vivint security plan is $199.99. After that, the recurring monitoring charge is $24.99 to $44.99 a month, and installation is required, so the real outlay is the entry figure plus the monthly fee for as long as the system stays in the house. Contract terms run 0 to 60 months, which sets how long that addition continues.
Is there a contract, and how long does it run?+
Contract terms run 0 to 60 months, spanning a short arrangement at one end and a multi year tie in at the other. That length decides how much of the $24.99 to $44.99 monitoring fee you pay in total, so the term matters more than the entry figure of $199.99 for anyone planning to move within a few years.
