Test Report

Smart radiator thermostats tested - smarter heating by mobile phone

Smart radiator thermostats can be controlled from anywhere via mobile phone. Many of the eleven devices tested regulate the temperature reliably - only two are easy to operate. We tested eleven smart thermostats, with our test results you will find the best smart radiator thermostat for your needs. Almost as good as the test winner is our significantly cheaper price tip, both regulate the room temperature reliably and are the only ones in the tested that are easy to operate.
