It’s normal for different sensors to show slightly different temperatures, this isn’t something to worry about. If you use a Shelly thermostat, Havenwise uses it at main source of truth for your room temperature, so that’s the reading you should refer to.
There are a few reasons why readings may vary:
📊 Measurement & Reporting
The Shelly H&T Gen3 measures temperature every minute
The display updates only when the temperature changes by 0.2°C or more
The app updates only when the temperature changes by 0.5°C or more
Because of this, the display and app might show slightly different values
🌡️ Self-Heating Prevention
The device pauses for 5 minutes after each measurement to avoid self-heating
This ensures more accurate readings over time
📍 Placement & Environment
Location has a big impact on readings, for example, near sunlight, radiators, or poor air flow
Try placing your Shelly in an open area that reflects your room’s average temperature
