A good wall transmitter is becoming an increasingly important component within Z-wave. Wired switches are increasingly being left out and lights turn on and off automatically based on your presence or on time. If you still want to be able to manually adjust it separately from your smartphone or tablet, you need a remote control or something on the wall. The Z-Push from Heat-it is perfect for this. You can stick it to something, but also integrate it into existing switch material from GIRA (system 55). The Z-Push is available in a 2 button version and one 8 button variant. With both, up to 20 unique units can be controlled via association groups and, depending on the chosen version, 2 or 8 unique scenes.
