You can automate up to 2 garage doors with a single Universal Relay. Always check your local safety regulations and test the device thoroughly once you wire and program it to prevent accidental operation. You can use a wired NC contact sensor on the input side of the Universal Relay to receive open/close notifications to your hub's interface and monitor the status of your garage door. You can also opt in for a wireless contact or tilt sensor to install on your garage door to track its position. It's recommended to have an audible alarm (like a loud siren) go off whenever the doors are being opened or closed remotely.

Follow the steps below to turn your Universal Relay into a DIY smart garage door opener solution on Hubitat:

1. WIRE THE UNIVERSAL RELAY ZEN17

The device will work great with simple momentary garage door wall switches. If your garage door opener uses a proprietary wireless control system, you will NOT be able to use the ZEN17 Universal Relay (or any other Z-Wave device) to control the opener.

If you have a simple one-button garage door switch, just use the below diagram to wire the Universal Relay next to it (you can wire up to 2 door switches to a single Universal Relay):

• WIRING TIPS: Always take "before" pictures just in case you need to restore the original set-up or send us images for consultation. use the correct screwdriver size for the terminal screws on your Universal Relay and wall switches (if connecting them). Use appropriate electrical tools when cutting, prepping, and stripping electrical wires. If you don’t have the necessary tools to perform the installation or are not sure which tools to use or how, please hire an electrician to complete the installation for you. 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: turn the circuit power off in the breaker panel before you start. Keep the Universal Relay unplugged from its power source.
• DISCONNECT THE SWITCH: Open the switch cover, you should see 2 wires coming to it from the opener. Leave them connected as they are
• CONNECT THE UNIVERSAL RELAY: Run 2 jumper wires between the wall switch screws and S1-C terminals on the Universal Relay as shown in the below diagram.

RESTORE POWER: Connect the opener and ZEN17 Universal Relay back to their power source. Click here for the recommended power supply to power the Universal Relay ZEN17. Please do NOT use laptop chargers or Apple accessories with the Universal Relay. NEVER connect AC/DC power and USB power to the ZEN17 at the same time.

2. INSTALL ADDITIONAL Z-WAVE DEVICES TO COMPLETE THE SET-UP

• OPEN/CLOSE SENSOR: You will need an open/close sensor to use the dedicated Garage Door Opener SmartApp we talk about below. We recommend using a wireless Z-Wave tilt sensor to reliably track the status of your sectional garage door but you can also use any Z-Wave contact sensor for that purpose. With the ZEN17 model, you can also use a wired contact sensor connected between the S1 and C input terminals on the Universal Relay as shown in the diagram above. You will need a NC sensor to best work in that type of installation. A NC security sensor will close the circuit when the magnet is close to the sensor (reporting closed status to your Z-Wave hub) and it will open the circuit when the magnet is away from the sensor (reporting open status to your Z-Wave hub).
• Z-WAVE SIREN: We recommend using a Z-Wave siren to sound an alarm whenever the door is being opened or closed remotely for added safety. You can use any Z-Wave siren for that purpose.

3. PROGRAM THE ZEN17 ON HUBITAT

1. Do NOT skip this step: Install a dedicated driver for a virtual Garage Door device that you'll use to open and close the garage door from your HE:
   • Open the Hubitat online dashboard in your browser.
   • Click on Drivers Code in the side menu.
   • In the top right corner, click on "+New Driver" and paste the code from the following link. Please click on this link to access the code for the driver, then copy ALL of the code from the page.
   • Click Save in the top right corner.
   • You'll see a Zooz Garage Door driver in your Drivers Code list now. No further action is needed for the driver. It will be used by the SmartApp to create a new device automatically once you complete the programming in step 2.
2. Install the parent App to program your garage door set-up in HE:
   • Stay in the HE dashboard.
   • Click on Apps Code in side menu.
   • In the top right corner, click on "+New App" and paste the code from the following link. Please click on this link to access the code for the handler, then copy ALL of the code from the page.
   • Click Save in the top right corner.
   • You'll see a Zooz Garage Door Opener in your Apps Code list now.
3. Install the child App to complete set-up:
   • Stay in the HE dashboard.
   • Click on Apps Code in side menu.
   • In the top right corner, click on "+New App" and paste the code from the following link. Please click on this link to access the code for the handler, then copy ALL of the code from the page.
   • Click Save in the top right corner.
   • You'll see a Zooz Garage Door Opener App in your Apps Code list now.
4. Add the ZEN17 to Hubitat by following the instructions in the manual (or the article here).
5. If you're using a contact sensor wired into the input side of the ZEN17 Universal Relay, go to the settings under Preferences in the ZEN17 main device view and change the switch type for R1 to contact sensor (do the same for R2 if you're automating both relays). If you're using a wireless contact sensor, just skip this step. Reload your device view and refresh the Hubitat interface page to display the additional inputs. You should now see 2 new open/close child devices in the Hubitat interface.
6. In the advanced settings, disable input/manual control for R1 (so that the sensor doesn't trigger the relay). Do the same for R2 if automating both relays. If you're using a wireless contact sensor, just skip this step.
7. Program your garage door in the SmartApp:

• Click on Apps in the side menu
• Click on "+ Add User App" in the top right corner
• Click on Zooz Garage Door Opener
• Click on "Create a Garage Door".
• Add a name to the new garage door to identify it in the App as well as in your general HE interface (it will use this name to create a new virtual garage door device).
• Tap on Select Relay Switch to choose the Relay (the child relay device not the master Universal Relay) connected to your garage door.
• Tap on Select Open/Close Sensor to choose the sensor device from your device list (either your wireless contact sensor or the device created on the ZEN17 input).
• Go through the other options in the app to make sure the pre-filled settings match your installation. We recommend leaving the auto-off timer at the default 2 seconds here. Operation Duration is set to 15 seconds which is the typical time it takes for a door to fully open or close but if your set-up is different, you can change it to the actual duration.
• Click Done.
• The set-up will now appear on the list of garage doors in your App, you can edit it or remove it anytime.

Control your garage door from Hubitat:

• Click on Devices in the side menu of the HE dashboard and locate the new new garage door device by the same name you entered in the App. 
• Click the open and close tiles to control the garage door and monitor its status. The open/close status is displayed on the right side under Current States based on the reports from your Z-Wave open/close sensor.
• Use the garage door device (rather than the ZEN17 Relay) in any automations, rules, scenes, or schedules programmed in your hub.

Once everything is programmed, test it a couple of times to make sure the set-up is fully functional and enjoy your new smart garage door!
