Plug the unit in and press the button 3 times in quick succession; the blue LED blinks during the interview.

03

Step 3: Tune the Parameters

Set Param 2 for LED mode, Param 4 for the auto-off timer and Param 6 for outage memory.

Step 4: Test Control and Automation

Toggle the load from the app, then unplug and replug to confirm it rejoins the mesh.

Troubleshooting FAQs

Direct solutions to common network, protocol, and pairing questions.

Q: Does the MP21Z need a hub?

A: Yes. It is Z-Wave, not Wi-Fi, so it needs a certified controller such as SmartThings, Hubitat, Home Assistant with a Z-Wave stick, Vera or Amazon Alexa. Alexa and Google only reach it through that hub.

Q: It stopped responding and the LED is dark, what now?

A: Press once to wake it, then unplug for 30s and reseat. If still dark, press 2x quickly and hold the 3rd press 10s to reset, then re-include. Persistent failure means replacement.
