Important safety information

Please read this manual carefully. Failure to follow the recommendations in this manual may be dangerous or may violate the law. The manufacturer, importer, distributor and seller shall not be liable for any loss or damage resulting from failure to comply with the instructions in this manual or any other material. Use this equipment only for its intended purpose. Follow the disposal instructions. Do not dispose of electronic equipment or batteries in a fire or near open heat sources.

What is Z-Wave?

Z-Wave is the international wireless protocol for communication in the Smart Home. This device is suited for use in the region mentioned in the Quickstart section.

Z-Wave ensures a reliable communication by reconfirming every message (two-way communication) and every mains powered node can act as a repeater for other nodes (meshed network) in case the receiver is not in direct wireless range of the transmitter.

This device and every other certified Z-Wave device can be used together with any other certified Z-Wave device regardless of brand and origin as long as both are suited for the same frequency range.

If a device supports secure communication it will communicate with other devices secure as long as this device provides the same or a higher level of security. Otherwise it will automatically turn into a lower level of security to maintain backward compatibility.

Use Cases.
Perfect for SMB owners?.
If you are a small or medium-sized business owner, you have probably struggled with energy overconsumption. Some machines and appliances are switched on all the time. With Shelly PRO EM-50, you can measure with utmost precision and reduce consumption by turning off load - water dispensers, laminating machines and lighting, during the night. The smart device can also be applied for preventative measurement by monitoring for abnormal behavior of HVAC, air compressors, refrigerator units and others.

Renewable energy ecosystem at home?.
If you have a photovoltaic system (PV) at home, Shelly PRO EM-50 can help you measure grid and imported energy from renewable sources. Moreover, it has configurable load control, which allows you to redirect any excess energy generated from renewable sources to electronic devices at your home and optimize your energy consumption. For example, you can use Shelly PRO EM-50 for charging your car or home appliances when your PV system provides excess energy. ?

Shelly Smart Control is here!
One app to control your spaces, energy consumption, and expenses. 

Full compatibility.
Shelly devices are compatible with Alexa, Google Home, Android and iOS. Together with the voice assistant, you can command Shelly devices using just your voice!

Prepare for Installation / Reset

Please read the user manual before installing the product.

In order to include (add) a Z-Wave device to a network it must be in factory default state. Please make sure to reset the device into factory default. You can do this by performing an Exclusion operation as described below in the manual. Every Z-Wave controller is able to perform this operation however it is recommended to use the primary controller of the previous network to make sure the very device is excluded properly from this network.

Safety Warning for Mains Powered Devices

ATTENTION: only authorized technicians under consideration of the country-specific installation guidelines/norms may do works with mains power. Prior to the assembly of the product, the voltage network has to be switched off and ensured against re-switching.

Inclusion/Exclusion

On factory default the device does not belong to any Z-Wave network. The device needs to be added to an existing wireless network to communicate with the devices of this network. This process is called Inclusion.

Devices can also be removed from a network. This process is called Exclusion. Both processes are initiated by the primary controller of the Z-Wave network. This controller is turned into exclusion respective inclusion mode. Inclusion and Exclusion is then performed doing a special manual action right on the device.

Quick trouble shooting

Here are a few hints for network installation if things dont work as expected.

  1. Make sure a device is in factory reset state before including. In doubt exclude before include.
  2. If inclusion still fails, check if both devices use the same frequency.
  3. Remove all dead devices from associations. Otherwise you will see severe delays.
  4. Never use sleeping battery devices without a central controller.
  5. Dont poll FLIRS devices.
  6. Make sure to have enough mains powered device to benefit from the meshing
