NOTES Standard warranty (included in purchase price): 3 Years warranty through manufacturer due to device malfunctions when it is used in user manual described conditions. While this is technically user-installable in many locales, we recommend consulting a licensed electrician to install automation components - in addition to being licensed to work with electrical devices, they are also familiar with local building codes. Manufacturer's note: Each Shelly device emits heat under load. Do not combine two or more Shelly devices stacked on top of each other in a confined space. There must be a minimum distance of 1 cm between them to allow for airflow.
