Submitted on 01/22/2020 Alarm Grid
The Somfy ZRSTi is a Z-Wave shade controller. It uses Radio Technology Somfy (RTS) to wirelessly control the compatible motors for shades, blinds, and curtains. The ZRSTi can convert this RTS signal to Z-Wave and vice-versa so that your Z-Wave controller can communicate with your Somfy Curtain Motor. When using the Somfy ZRSTi, you can only have the window coverings fully opened or fully closed. The unit does not allow for partial closing. Still, this is a rare example of a Z-Wave device that can be used to open and close your blinds or other window coverings. Since this device provides a useful function that is matched by few other devices, we have no issue giving the Somfy ZRSTi a 5-Star rating.
There are many things we like about the Somfy ZRSTi. For one, it integrates nicely with nearly any Z-Wave controller or hub, including most security systems that support Z-Wave. The module can simultaneously connect with up to 16 different Somfy Curtain Motors that use RTS communication. From there, you can actually program the Somfy ZRSTi with up to 16 Z-Wave slots (aka Nodes) on your Z-Wave controller to allow for individual control for each motor used with the ZRSTi module. We also appreciate the fact that the Somfy ZRSTi is nice and compact, meaning that it won't take up too much space in your home or business.
There are some downsides associated with the Somfy ZRSTi. For one, it can only be used with Somfy Motors that support RTS communication. Other curtain motors will not work with the ZRSTi. The fact that you can only use the ZRSTi to completely open or completely close your window coverings is somewhat of a letdown. There is no way to use the module to leave your curtains partially open. Lastly, the fact that this module only uses standard Z-Wave is disappointing, as the more advanced Z-Wave Plus communication protocol is known to work more reliably.
Overall, the Somfy ZRSTi is a very good product. It has some downsides, but it is one of the few Z-Wave curtain motor controllers available. For that reason, it gets a 5-Star rating from Alarm Grid.
Good: Works w/ Nearly Any Z-Wave Controller, Can Connect w/ Up to 16 Somfy Curtain Motors Using RTS, Small & Compact Design
