Smart Thermostats / Google Nest Thermostat (2020) vs ecobee Smart Thermostat Essential
Google Nest Thermostat (2020) vs ecobee Smart Thermostat Essential
Google Nest Thermostat (2020)
Matter-certified and usually C-wire-free, but it does not learn and takes no sensors.
Wins overall by 0.2 points
Quick Verdict
The Google Nest Thermostat (2020) wins by 0.2 points, which is not enough to settle it. The cheapest way into ecobee's sensors — but it is the ecobee that omits the C-wire kit. Pick on the specs that matter to you, not the overall score.
The Google Nest Thermostat (2020) and ecobee Smart Thermostat Essential are both closely matched smart Thermostat models, and the Google Nest Thermostat (2020) is $10 cheaper than the ecobee Smart Thermostat Essential ($129.99 vs $139.99). On Multi-Room Sensing, the ecobee Smart Thermostat Essential leads (6.0 vs 1.5/10) — remote sensors: included or extra, how many pair, and whether they read occupancy or only temperature. On C-Wire Freedom, the Google Nest Thermostat (2020) leads (8.0 vs 4.5/10) — how likely this thermostat is to run on the wiring you already have — whether it needs a common wire, and whether the workaround is in the box, sold separately, or an electrician's visit. The single biggest cause of returns in this category.. On Smart Home Integration, the Google Nest Thermostat (2020) leads (8.5 vs 6.5/10) — matter, Apple Home, Alexa and Google support — and how much each one actually exposes. Overall, the Google Nest Thermostat (2020) scores 6.6/10 across our 8 scoring categories versus 6.4/10 for the ecobee Smart Thermostat Essential, though the gap is close enough that your specific use case should decide it. Below, we break down the full spec sheet, category-by-category scores, and exactly who should buy which one.
Side-by-Side Comparison
| Spec | Google Nest Thermostat (2020) | ecobee Smart Thermostat Essential |
|---|---|---|
| Price | $129.99 | $139.99 |
| Release Year | 2020 | 2025 |
| System Voltage | Low voltage 24V only — furnaces, air conditioners, boilers and heat pumps. Not for 120/240V line-voltage heat | Low voltage 24VAC gas, oil and electric forced-air systems. Not for 120/240V line-voltage heat |
| C-Wire Required | Not in most homes, but Google's own store page states heating-only, cooling-only, zone-controlled and heat pump systems need the Nest Power Connector or a C wire | Yes — powered through the C and R terminals. This is the ecobee that does not include the fix |
| Adapter / Power Kit Included | No — Nest Power Connector is a separate $24.99 accessory | No. The Power Extender Kit that ships free with the Premium and Enhanced is a $24.99 accessory here, and the trim plate is another $14.99 |
| Heating & Cooling Stages | Google's tech-spec page lists conventional single-stage systems and heat pumps with auxiliary or emergency heat. Unlike the Learning Thermostat, it does not publish multi-stage conventional support | 2H/1C or 1H/2C conventional. The single OB terminal doubles as W2 or Y2, so you get one extra stage in total, not two |
| Heat Pump & Aux Heat | Yes, with auxiliary and emergency heat | Yes, heat pump 2H/1C. No second compressor stage |
| Humidifier / Ventilator Terminals | Not published for this model. Google lists humidifier, dehumidifier and ventilator support only on the Learning Thermostat | None. There is no ACC terminal, so no humidifier, dehumidifier or ventilator control |
| Remote Sensors | None. Google states explicitly that the Nest Thermostat is not compatible with the Nest Temperature Sensor | None in the box. Up to 32 SmartSensors (2nd gen or newer) pair, sold separately. ecobee states the original ecobee Room Sensor is not compatible |
| Occupancy Detection | Built-in motion sensor at the thermostat plus phone-location Home/Away. No remote occupancy sensing of any kind | None built in — the Essential drops the radar occupancy sensor that the Premium and Enhanced have. Occupancy-based eco+ features need a SmartSensor you buy separately |
| Matter Support | Matter-certified — works with Google Home, Alexa and Apple Home | Not listed on ecobee's spec page for this model |
| Voice & Smart Home Platforms | Google Home app (required), Amazon Alexa, Apple Home via Matter | Apple HomeKit, Amazon Alexa, Google Assistant. No built-in voice, no speaker |
| Utility Rebates & Demand Response | Rush Hour Rewards and Nest Renew. Google's help page also notes Seasonal Savings currently supports the Nest Thermostat (2020) and Thermostat E, nudging setpoints up to 2°F over three weeks | eco+ Community Energy Savings with 150+ utilities; enrolled demand events move your setpoint 1-4°F for a few hours, with per-event opt-out |
| Account or Subscription Needed | No subscription, but a Google account and the Google Home app are required | No subscription. A free ecobee account is required |
| Warranty | 12 months | 36 months |
| Colors | Snow, Charcoal, Sand, Fog | Black front with white sides and back |

Pros & Cons
Google Nest Thermostat (2020)
Pros
- +Matter certification at $129.99 puts it in Apple Home, which no ecobee, Sensi or Amazon model here manages
- +Same Power Sharing wiring trick as the Learning Thermostat, so it usually installs without a C wire
- +Battery backup on two AAA cells — the Amazon, X2S and Sensi Touch 2 all go dark if 24V power drops
- +Cheapest way into the Google ecosystem with a real touch UI, at less than half the Learning Thermostat's list price
Cons
- −No remote sensor support at all — Google says outright it is not compatible with the Nest Temperature Sensor, so this is a one-room thermostat
- −It does not learn. Google gives it guided schedule setup instead, which is the single feature people think they are buying when they buy 'a Nest'
- −Google's spec page only claims single-stage conventional support; two-stage furnace owners should check compatibility before buying
- −No published humidifier, dehumidifier or ventilator terminals
- −1-year warranty, against 2 on the Learning Thermostat and 3 on every ecobee here
ecobee Smart Thermostat Essential
Pros
- +Cheapest route into ecobee's SmartSensor ecosystem — 32 occupancy-sensing sensors will pair to a $140 thermostat
- +Wi-Fi 6 and Bluetooth LE 5.4 make it the most modern radio stack in this comparison
- +3-year warranty at $139.99, which beats Google's 1-year on the similarly priced Nest Thermostat
- +Full colour touchscreen rather than the monochrome or button-driven UI at this price from Resideo and Copeland
Cons
- −The Power Extender Kit that comes free with both bigger ecobees costs $24.99 here, so a C-wire-less home pays $165 not $140
- −The radar occupancy sensor is gone — the Essential cannot tell whether you are in the room without a $50 SmartSensor
- −No accessory terminal at all: no humidifier, dehumidifier or ventilator control
- −Heat pump support stops at 2H/1C, so cold-climate multi-stage systems are out
- −Launched at $129.99 in March 2025 and now lists at $139.99 — an eight percent rise in the first year
