You can automate up to 3 garage doors and monitor the status of 3 dry contact sensors with a single MultiRelay. Please ensure you have verified the local safety regulations before installing the ZEN16. Always test the device meticulously once you have wired and programmed it to prevent accidental operation. To accurately monitor the status of your garage door, you can use a wired NC contact sensor on the input side of the MultiRelay. This will allow you to receive open/close notifications through your hub's interface. Whenever the doors are being opened or closed remotely, we recommend having an audible alarm (like a loud siren) go off for added safety.

Separate monitoring of contact sensors on the input can be done with hardware version 2.0 and higher of the ZEN16. Earlier hardware versions do not have this capability. You can still use it with your garage doors and wireless tilt sensors with these instructions.

Please follow the instructions below to automate your garage door opener on a budget with a DIY solution from the ZEN16 VER 2.0 MultiRelay:

1. WIRE THE ZEN16 MULTIRELAY

If you utilize a momentary switch to operate your garage door opener, the ZEN16 will work seamlessly. Please note, however, that if your garage door opener uses a proprietary wireless control system (MyQ), you will NOT be able to use the ZEN16 MultiRelay (or any other Z-Wave device) to control the opener.

The diagram below shows an installation with a simple one-button garage door switch, a dry contact sensor, and the ZEN16 MultiRelay. If this matches your installation, please follow the below diagram to wire the ZEN16 next to the momentary switch (you can wire up to 3 door switches to a single MultiRelay):

• WIRING TIPS: Please ensure you take "before" pictures prior to installing the ZEN16. In case you need to restore the original set-up, or reach out to us for input, we will need to verify the original wiring to ensure the installation is correct. Always use the correct screwdriver size for the terminal screws on your MultiRelay and wall switches (if connecting them). Verify you have the correct electrical tools for cutting, prepping, and stripping electrical wires. If you lack the necessary tools to correctly perform the installation or are unsure which tools to use or how, please hire an electrician to complete the installation for you. Please follow the National Electrical Code and your local safety regulations when performing the installation, including (but not limited to), choosing the correct gauge of jumper wires. The recommended gauge for 15 Amp circuits is 14 AWG and 12 AWG for 20 Amp circuits.
• POWER OFF: Always ensure the circuit power is off in the breaker panel before you start. Keep the MultiRelay unplugged from its power source while performing the installation.
• DISCONNECT THE SWITCH: With the switch cover open, you should see 2 wires coming to it from the opener. Leave them connected as they are
• CONNECT THE MULTIRELAY:  Connect the 2 wires coming from the opener to the R1 terminals on the MultiRelay, and connect the NC sensor to the Sw1 inputs.

• RESTORE POWER: Connect the opener and ZEN16 MultiRelay back to their power source. Click here for the recommended power supply to power the MultiRelay ZEN16. Please do NOT use laptop chargers or Apple accessories with the MultiRelay. NEVER connect DC power and USB power to the ZEN16 at the same time.

3. PROGRAM THE MULTIRELAY

There are many different ways to program the MultiRelay as a garage door opener, depending on the Z-Wave hub you're using. Here are a few examples for the most popular systems:

• Z-Box:
  • The relays need to be in the off position before changing any of the settings or testing the device.
  • Set Parameter 2 (Input Type for Sw 1), and Parameters 3 and 4 (if you are using a contact sensor on Sw input 2 and Sw input 3) to Value 11: garage door mode for the relay (momentary contact) and door sensor type for the input (use with wired analog door/window sensors and garage gate openers).
  • Reconfigure/Re-interview the ZEN16. You will now have a new child device for each input you have adjusted the setting for.
  • Set Parameter 12 (Enable or disable switch (input) control of Relay 1) to Value 0 (disabled). Set Parameters 13 & 14 to Value 0 as well if using contact sensors on the Sw2 and Sw3 inputs respectively. The contact sensor will now send a report of the open close status of the garage door, and you can control the door from the relay child devices.
  • Anytime you turn on any of the child relays now, the garage door opener will activate to either open or close the garage. The relay will automatically turn off a couple of seconds later, simulating momentary contact and you will receive an open or closed report from your contact sensor on the Sw input child device.
• SmartThings:
  • Install the custom driver for the MultiRelay before adding it to SmartThings. Click here for detailed instructions to add the device to SmartThings.
  • Open your SmartThings app and click on the MultiRelay in your device list.
  • Make sure that all of the child relays are in the OFF state.
  • Click the 3 dots in the top right corner and click on Settings.
  • Set the Input Type for Sw 1 (and Sw2, Sw3 if using) setting to "Garage door mode for the relay."
  • Exit the settings so they can save, then exclude and re-include the ZEN16 (the settings above will remain, and you will now have a new child device for each input you have adjusted the setting for.
  • Click the 3 dots in the top right corner and click on Settings.
  • Enable Switch Input Control setting for the Sw input you are using the contact sensor on. The contact sensor will now send a report of the open close status of the garage door, and you can control the door from the relay child devices.
  • Anytime you turn on any of the child relays now, the garage door opener will activate to either open or close the garage. The relay will automatically turn off a couple of seconds later, simulating momentary contact and you will receive an open or closed report from your contact sensor on the Sw input child device.
• Hubitat: 
  • Install the custom driver for the MultiRelay before adding it to Hubitat.
  • Click here for instructions to add the device to Hubitat.
  • The relays need to be in the off position before changing any of the settings or testing the device.
