ThermalTrace vs an Ecobee Thermostat for freeze protection in unheated spaces
Ecobee does one job very well: run the furnace and track the temperature of the room it's in. An unheated garage, crawlspace, or workshop is unconditioned by design, so Ecobee has no reading from it at all -- there's nothing to alert on. ThermalTrace puts a dedicated probe in that space, and if you connect your Ecobee account (Pro), every freeze alert shows your house's indoor temperature and whether it's actively heating, so you can tell at a glance whether the cold is expected (garage is unconditioned, house is fine) or something's actually wrong.
ThermalTrace vs Ecobee Thermostat
| Capability | ThermalTrace | Ecobee Thermostat |
|---|---|---|
| Primary job | Freeze/leak monitoring for any space | HVAC control for conditioned space |
| Sees an unheated garage/crawlspace | Yes: dedicated probe | No: unconditioned spaces aren't on the loop |
| Freeze/leak alerts (SMS, push, email) | Yes, plus remaining-hours time-to-freeze | No |
| Shows thermostat reading on freeze alerts | Yes, if connected (Pro) | N/A |
| Controls heating schedules | No | Yes |
| Complements the other? | Yes: connect both | Yes: connect both |
When to choose which
Choose ThermalTrace when
- You have a garage, crawlspace, basement, or shop that isn't on Ecobee's heating loop
- You want an alert from the specific unconditioned space, not an inference from the thermostat
- You already use Ecobee and want its reading shown alongside freeze alerts, not replaced
Choose Ecobee Thermostat when
- You only need the temperature of Ecobee-conditioned living space
- You want to control heating/cooling schedules, not just monitor a cold space
- You don't have a separate unconditioned space that needs its own probe
Frequently asked questions
Straight answers for people comparing ThermalTrace to Ecobee Thermostat.
Does Ecobee see my unheated garage?
Usually no. Ecobee reports conditioned living space (or SmartSensors on that loop), not a detached garage or crawlspace by default.
Can ThermalTrace show Ecobee readings?
Yes on Pro when Ecobee OAuth is available and connected. If Ecobee developer signup is closed, use Home Assistant → ingest → Indoor reference instead.
Should I replace Ecobee with ThermalTrace?
No. Ecobee runs HVAC; ThermalTrace monitors unconditioned spaces. They complement each other.
