Handcrafted Quality
Every UltimateSensor is handcrafted with care in the Netherlands:

- Hand-folded packaging — Even our product boxes are folded by hand
- Dual quality control — Each unit passes inspection by two independent team members during assembly and before shipping
Product-Specific Information
Housing & Finish
The UltimateSensor housing is 3D-printed and may have visible layer lines, which is normal for this manufacturing process.
Important:
- Avoid placing in direct sunlight — UV exposure can cause yellowing of the plastic
- Yellowing or discoloration from sunlight is not covered under warranty
- Handle with care to avoid scratches
Sensors & Accuracy
We strive for accurate sensor readings, but please note:
- Sensor accuracy depends on proper placement and calibration
- Environmental factors (heat, humidity, placement) affect readings
- Sensors may require calibration after relocation
- Third-party sensor specifications are provided by their manufacturers
We are not responsible for:
- Inaccurate readings due to environmental factors
- Changes in sensor behavior due to third-party software updates
- User modifications to sensor configuration
Third-Party Modifications
The UltimateSensor uses open-source ESPHome firmware, and we encourage tinkering! However:
- Custom firmware modifications are not covered under warranty
- Hardware modifications (swapping sensors, soldering) void the warranty
- If you modify the device and need help, our Discord community is a great resource
