Shelly Temperature Add-On Sensor Controller

KEY FEATURES Add temperature sensing for up to 3 zones to Shelly 1, Shelly 1 UL, and Shelly 1 PM modules. Select up to 3 sensors when purchasing NOTES Requires a Shelly switching controller (i.e. Shelly 1, Shelly 1 UL, Shelly 1 PM) which is not included, but available separately Standard warranty (included in purchase price): 24-month manufacturer's warranty 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.
