Side-by-Side Comparison
| Spec | Mysa Smart Thermostat LITE for Electric Baseboard Heaters | Honeywell Home X2S (RTH2CWF) |
|---|---|---|
| Price | $99.00 | $79.99 |
| Release Year | 2023 | 2025 |
| System Voltage | Line voltage 120V or 240V AC, 16A maximum — 3,800W at 240V or 1,900W at 120V, identical to the V2. Not compatible with any 24V system | Low voltage 24V. Resideo states it does not work with electric baseboard heat at 120-240V |
| C-Wire Required | Not applicable — line voltage. Both line conductors must be present in the gang box | Yes, hard requirement. Resideo states a constant 24V C-wire supply is needed and the X2S is not battery powered |
| Adapter / Power Kit Included | Not applicable | No adapter of any kind is included |
| Heating & Cooling Stages | Heating only, on/off line-voltage switching. No cooling and no staging | Up to 2 Heat/2 Cool conventional |
| Heat Pump & Aux Heat | No. Same exclusions as the V2: no 24V furnaces or central air, no millivolt, no central hydronic boilers, no electric in-floor heating | Yes — up to 2 Heat/1 Cool heat pump with electric backup |
| Humidifier / Ventilator Terminals | None | None published. Humidity is monitored and displayed, not controlled |
| Remote Sensors | None. One thermostat per heater circuit | None. There is no room sensor option for this model |
| Occupancy Detection | None. The LITE drops the V2's light and proximity sensors entirely, and there is no humidity sensor either. Away control is app geofencing | None. Away behaviour comes from geofencing in the First Alert app |
| Matter Support | Not listed for the baseboard models | Matter certified — but Matter Alpha's reviewer could see temperature, humidity and mode in SmartThings and could not get setpoint changes to take effect, which breaks the automations Matter is meant to enable |
| Voice & Smart Home Platforms | Mysa app, Apple HomeKit, Amazon Alexa, Google Home | First Alert app by Resideo (required for setup and to generate the Matter code), Amazon Alexa, Google Assistant, Apple Home via Matter |
| Utility Rebates & Demand Response | Mysa states the LITE supports utility demand-response programs and it is stocked in US utility rebate marketplaces | ENERGY STAR certified. Resideo's launch materials specifically call out enabling enrolment in utility energy-management programs |
| Account or Subscription Needed | No subscription | No subscription. A First Alert account is required |
| Warranty | 60 months | 24 months |
| Colors | White | Gray, White |

Pros & Cons
Mysa Smart Thermostat LITE for Electric Baseboard Heaters
Pros
- +Under $100 for a real line-voltage smart thermostat with HomeKit, Alexa and Google support and a 5-year warranty
- +Identical 16A / 3,800W switching capability to the $159 V2 — you lose features, not capacity
- +Physically the smallest thermostat here, which matters when you are fitting several in one apartment
- +Launched at $109 in 2023 and now sells for $99, one of the few products here whose price has gone down
Cons
- −No energy monitoring, no humidity sensor and no light or proximity sensors — the V2's whole value-add is stripped out
- −Buttons rather than a touchscreen, and Mysa's app carries most of the configuration
- −Heating only. No cooling, no staging, no accessory control
- −No Matter on the baseboard line
- −Still one unit per heater circuit, so a whole-home baseboard retrofit is a multi-hundred-dollar project
Honeywell Home X2S (RTH2CWF)
Pros
- +Matter certified, ENERGY STAR certified and dual-band Wi-Fi for $79.99 — nothing else here does all three that cheaply
- +2H/2C conventional staging is more than the similarly priced Sensi Lite or the Nest Thermostat publish
- +Mounts on Resideo's UWP plate, the same system professional installers use, which makes wiring tidy
- +2-year warranty at $80, double what Amazon and Google give at this price
Cons
- −A C wire is mandatory and no adapter is included — in a four-wire house this $80 thermostat becomes an electrician's callout
- −Matter works only for reading state in at least one reviewer's testing: setpoint changes sent over Matter did not stick
- −You have to install the First Alert app to get a Matter pairing code, so Matter does not free you from the vendor app
- −No room sensors and no occupancy sensing at all — this is strictly a one-room thermostat
- −No humidifier, dehumidifier or ventilator control
