Warranty

As of 30 October 2026

In short

• You have the statutory warranty for defects under Swiss law: 2 years from delivery.
• If your product is defective, we repair or replace it free of charge, including shipping. If this is not possible or does not work, you can choose a price reduction or your money back.
• To make a claim, write to us at hello@sunmatched.com.

Which rules apply

The warranty applies to all our customers. It is governed by the Swiss Code of Obligations (Art. 197 ff. OR).

• The warranty period is 2 years from delivery (Art. 210 OR). If you buy as a consumer, for personal or family use, this period cannot be shortened by contract to less than two years for new goods (Art. 210 para. 4 OR).
• If you are a consumer living in Liechtenstein, you also keep any further rights that the mandatory consumer law of Liechtenstein gives you.

What is covered

The warranty covers defects that the product already had at delivery, even if they show up only later. A product is defective, for example, if it does not have the characteristics described on the product page, or if it is not fit for its normal use.

The warranty does not cover problems that arise after delivery from other causes, in particular:

• improper use or use against our safety instructions, for example heat above 60 °C, moisture, a fall or an unsuitable power supply;
• opening the case, or repairs and modifications that we did not make;
• normal wear of the adhesive strip.

What we do if your product is defective

1. We repair the product or replace it with a new one. This is free of charge for you, including shipping both ways.
2. If repair or replacement is not possible, fails or takes unreasonably long, you can choose: a price reduction, or you return the product and get the purchase price back. If the defect is only minor, a price reduction may be the only appropriate remedy (Art. 205 para. 2 OR).

How to make a warranty claim

1. Write to us at hello@sunmatched.com. Give your order number and the serial number from the label, describe the problem and, if possible, add a photo or a screenshot.
2. We reply as soon as possible. Sometimes a setting or a firmware update solves the problem.
3. If the product has to come back to us, we tell you how to send it, and we pay for shipping.

Please check the product after delivery and report a defect as soon as possible after you notice it. We accept a report within two months of discovering the defect as on time.

Firmware updates

We keep developing the firmware of our sensors. We provide firmware updates free of charge, including security updates, for as long as you can reasonably expect for a device of this kind. The updates are signed: the sensor only accepts firmware from us. You install them over the air with our app (at present for Android).

For each update, we describe what it changes. Please install updates within a reasonable time. If you do not install an update that we have made available and told you about, we are not liable for a defect that only this update would have fixed.

Pioneer batch

Our sensors come from our first production batch. We have tested them, but data from several years of use in real homes is still being collected, for example on how the energy store and the solar cell age over time. We will update our product information as we learn more. This does not limit your statutory warranty rights.

Functions marked "beta"

Some functions are marked "beta", at present the Matter over Thread mode. They are still being developed, can contain errors and can change with updates. We point this out so that you can base your purchase decision on the functions that are not marked beta. This does not limit your statutory warranty rights.

No separate guarantee

We do not give a separate guarantee in addition to the statutory warranty.

Returns and claims for damages

Our voluntary 30-day return policy applies in addition to the warranty: see our page "Returns". For claims for damages, the liability rules in our terms and conditions apply.
