How I Installed the Meross/Refoss Garage Door Opener for HomeKit

I spent a little under 2 hours installing a new HomeKit garage door opener from Meross/Refoss. For $35 on Amazon, it works surprisingly well. The included instructions are bad. They don’t show exactly how everything should be setup. But the existing customer-submitted videos (like this one by Nick) on Amazon clearly show what needs to be done. I probably could have done it in 45 minutes if I wasn’t interrupted in the middle of the install. You don’t need to hire an electrician.

I had the purple learn button but didn’t have to order anything extra from Meross support to get it to work.

You will need:

  • Very small flathead screwdriver, the kind built into Swiss army knives
  • Ladder
  • 13mm or smaller wood cable staples, the kind you hammer in
  • Hammer
  • Phillips screwdriver
  • Duct tape for testing cable positioning

Here’s what I did:

  1. Plug the Meross device into power. Turn on your wireless router’s 2.4GHz mode. Connect to HomeKit. (I had to attempt the connection twice.) Then unplug both the Meross device and the (Chamberlain) garage door opener itself.
  2. Locate the 2 wires used by your existing garage door button and jam the ones from the Meross device into the same 2 holes – so you have 2 wires in each hole. For my Chamberlain opener, this meant the blue wire on the left, grey wire on the right. Don’t touch the other 2-3 holes. Use the very small flathead screwdriver to pull down on the socket clamps so you can fit the wires in.
  3. String the long black Meross wire along the garage ceiling to the sensor cable. Plug everything back in. Test positioning of the sensor by opening and closing the garage door until you get the position right. Use duct tape to hold the cable in place while testing. If you have an exposed wood garage ceiling, hammer cable staples into the wood to hold the wire in place. Finally, screw the sensor into position.
Step 2: plug the two Meross wires into the two holes here alongside the existing wires (ignore the bit about wire stripping)

So far, in the hour or so which I’ve been testing it, it has worked well from Apple HomeKit. You don’t need to use the janky Meross/Refoss/eHomeLife app if you have HomeKit.

If you get obstruction errors, ensure the magnet piece hasn’t been jostled out of the way.

Here’s what the finished product looks like:

Be careful not to get any wires anywhere close to the garage door opener chain

Not bad for less than 2 hours of work! (And if you’re handy, this should be a 30 minute job.)

Now I don’t have to go searching for the (usually lost) garage door opener remote control, or worry about changing the batteries in it. Plus I get alerts if the garage door is left open.
