Google Nest Thermostat (Charcoal) vs Mysa Smart Thermostat V2 for Electric Baseboard Heaters (BB.2.0.01.NA-US)
These are side-by-side facts taken from each product guide: published specifications, strengths and caveats as their sources state them. This page is not a test, a ranking or a verdict about which model is better.
Google Nest Thermostat (Charcoal)
Single-stage 24V systems that need a schedule and app control, not multi-stage equipment
Google's entry thermostat: a 2.4-inch touch-bar disc powered from HVAC wiring with two AAA backup cells. Google lists one stage of heating and cooling plus a second stage of one or the other, or a heat pump with aux or emergency heat. Matter certified, works with Hey Google and Alexa. The trim plate and the steel plate are both sold separately.
Published specifications
- Maker: most 24V systems; one stage heat and cool plus a second stage of either; heat pump with aux or emergency heat
- Maker: works with multi-zone systems but needs one thermostat per zone
- Maker: designed to work without a C wire; heating-only, cooling-only or zone-controlled systems may need one
- Maker: primary power from HVAC wires, backup 2 x AAA 1.5V; under 1 kWh a month
- Maker: Wi-Fi 2.4 GHz and 5 GHz plus Bluetooth LE; Matter certified; Hey Google and Alexa voice control
- Maker: 3.3 in diameter, 1.07 in deep, 4.9 oz; 2.4-inch 240x320 display; 1-year standard warranty
Strengths
- Works without a C wire in most homes, on either 2.4 GHz or 5 GHz Wi-Fi
- Matter certified with Hey Google and Alexa voice control, and a published one-year warranty that matches the listing
- Built-in motion sensing turns it down when nobody is home, with schedule suggestions in the app
Caveats
- Only one extra stage: no two-stage heat plus two-stage cooling, and no multi-stage heat pump support
- Trim plate and steel plate are both sold separately, and the steel plate is required on an electrical box
- Setup needs the Google Home app and a Google account, and the listing states there is no lock feature
