## Questions & Answers

**Q: Can I hook two  boards up to one phone?**
A: You can control multiple boards with a single device.

**Q: how much current does it require at 5 volts dc?**
A: 250mA minimum

**Q: When I receive the unit, all I have to do is download app to phone, connect it and it will work???No programming by me??**
A: You have to use the app to set it up with your wi-fi and password, and set it to do what you want it to do. In my case, I wanted to use it as a momentary contact switch, so I set the duration of the connection closure to the shortest time allowed, and it works great to open and close a driveway gate, you will need to power it. In my case, the DC from the gate controller power supply was within the voltage range for the device. Otherwise you will need a “wall wart” or other power.

**Q: I have an outside doorbell, which, when pressed, in my internal unit triggers an electronic buzzer. i saw a12v tension when pressed. can i use your de**
A: Probably 12V AC ?

    Automate your garage door - It's easy and cheap
  

*by M***S on Reviewed in the United States on 27 December 2018*

Showed up fast, works perfectly.  Put in a box (you can buy the one Amazon recommends or find another and drill holes in the sides so you can run the wires to it.  Using it for my garage door with Google Home.  Simple to connect although to find the app you have to search "Smart ewelink" not just "ewelink".  Press the button nearest the center to get it set up via the app and connected to your Wi-Fi.  The other button changes modes, you want to press it once to have it be a momentary switch.  Connect your garage door wires to the "Com" and NO" connectors, plug it in using a micro USB cable and power supply (not included) and it works great.  The only issue is it works just like your garage door button - you push it (you say "Ok Google...  Garage On) and it triggers the door button, but you don't know if it is opening or closing.  You really need a camera (like the $25 WYZE cam) so make it complete so you can SEE what it is doing.  I am going to buy another one for my other garage door!

    great smart relay, lots of features, easy to use
  

*by P***L on Reviewed in the United States on 2 September 2022*

I've used several of these in different customers homes and have not had one die, had no complaints and never had to make a follow up call to reprogram. The only thing I didn't like is you cant set it up with Android 12, had to use a android 10 tablet. Any Android can operate it , just cannot set it up. Ive used 6, 7, & 10. Good product
