Introduction to Shelly devices

Shelly® is a line of innovative microprocessor-managed devices, which allow remote control of electric appliances through a mobile phone, tablet, PC or home automation system. Shelly® devices can work standalone in a local Wi-Fi network or they can also be operated through cloud home automation services. Shelly® devices can be accessed, controlled and monitored remotely from any place the user has internet connectivity, as long as the devices are connected to a Wi-Fi router and the Internet. Shelly® devices have built-in web servers through which the user can adjust, control and monitor them. The cloud function can be used if it is activated through the web server of the device or the settings in the Shelly Cloud mobile application. The user can register and access Shelly Cloud using either Android or iOS mobile application, or with any internet browser at

Shelly® devices have two Wi-Fi modes – Access Point (AP) and Client mode (CM). To operate in Client Mode, a Wi-Fi router must be located within the range of the device. Shelly® devices can communicate directly with other Wi-Fi devices through HTTP protocol. An API is provided by Allterco Robotics EOOD. For more information, please visit

Shelly® TRV (the Device) is an intelligent Wi-Fi-connected, self-regulating valve fitted to a hot water heating system radiator. It can control the temperature of a room by changing the flow of the hot water through the radiator. Shelly® TRV can maintain the room temperature according to a set weekly schedule. If needed, the temperature can be changed at any time by pressing the buttons on the device, or through your mobile phone, tablet or PC. Shelly® TRV is powered by a built-in rechargeable battery. The battery can be recharged via a USB-C connector. Shelly® TRV is designed to work without recharging for 2 years, but this depends on the specific working conditions, such as how often it is necessary to adjust the hot water flow, Wi-Fi signal strength and wireless network quality. (fig.1)

Installation Instructions


  •  The product is intended for indoor use only.
  • Protect the product from dirt and moisture.
  • Do not use the product in a damp environment and avoid splashing water.
  • Ensure that the radiator is turned off and has cooled down before beginning the Device installation.

Compatible valves
If you already have thermostatic radiator valves, which typically have a dial on top with numbers from 1 to 5, most probably, your radiators are compatible with Shelly® TRV. Check the list of compatible radiator valves by brand and model at Radiators with manual valves are not compatible with Shelly® TRV. Manual valves are typically small and discrete. They are standard when you have a separate thermostat in the room or a central thermostat. If your radiator valves are not compatible you can use one of the adapters included in the box. (fig.2)

Remove the existing thermostatic radiator valve – (fig.3)

  •  Turn the dial counterclockwise until the valve is fully open.
  •  Unscrew the metal ring counterclockwise to remove the valve.

Install Shelly® TRV

  •  Check if you need an adapter and, if necessary, mount the suitable one before installing Shelly® TRV. (fig.4)
  •  Fasten the Shelly® TRV to the radiator valve by turning the metal ring clockwise. Do not fully tighten the ring.
  •  Place the Device display in the correct position and then fully tighten the metal ring.

CAUTION! Do not try to rotate the Device, if the metal ring is fully tightened. This can damage it.

Switch on the Device

  • Press briefly the Device Reset button. The screen will light up with the CL message and the motor inside will turn in both directions. This is the calibration process.
  • If the calibration process is successful, the screen will display AP and the Device is ready to be connected to your Wi-Fi network.
  • If the calibration is not successful, E1 message will be displayed. The reason is either the ring is not tightened enough or the Device is not properly mounted to the radiator.
  • Try tightening the ring or remove the Device and carefully mount it again. Press and holding for 3 seconds any of the Up and Down buttons. Then press Down button a couple of times.
  • The Device will try to calibrate again.

IMPORTANT: If the Device has not been added into your Wi-Fi network in 3 minutes, it will switch off. Press briefly the Reset button to start it again. If needed, the Device can be switched off manually by pressing briefly the Reset button while the Device is in AP mode.
