eWeLink Zigbee Two-Channel Relay

This device works with the Zigbee multi switch DTH.

Has options of:

Momentary operation on either channel, independently.

ON/OFF independently of both channels.

Interlock mode, polarity reversing operation. (can also be configured for 3 wire high/low fan speed etc…)

RF433 Remote (FOB) connectivity

I actually expected this to be a problem to get working, but pretty breezy.

Works this linear acuator wonderfully.

Show’s as Router Node… No issues so far.

4-channel version also available.

Hubitat discussion:


Nice find! I’ve been looking for something like this because I really didn’t want to use FortrezZ’s zwave MimoLite device.


I’m with ya…

I’ve been dreaming of something like this, easily integrated into solar banks. I think this might be it. Several projects have been waiting on this.

Will have to see what the power consumption is, but it will probably be manageable.

Coming up on vacation, and needed a way to let the cat in occasionally, through a sliding glass door. The acuator will do it. Those Smartthings cams are finally gonna be put to good use too. Have to make sure kitty is clear of the door… ehh. I’ll have to put in a anti-squish limit switch too…

fun stuff


I’ve been looking at this too, but I wish it didn’t require a separate supply for logic power. Some of the zigbee wall warts do this, but require nema plugs in/out instead of screw terminals which is more flexible.

I’m not a fan of the screw terminals on this device, mainly because the metal is so soft.

I think as long as you are powering your end devices with 7-32v, you can use the same power for the device as for the relays as long as you make jumpers to relay side. That’s probably obvious, but I was a little nervous about doing that with the 12v acuator, not knowing what to expect with the current reversing on the relay side.

I would have like to have seen terminals for external momentary switches, but I suppose having the ability to use RF remotes is a good consolation.

There are a few variants of this style of multi relay, so maybe more options are in the works.



are there somebody who tried use 4ch version? I have it on the table and trying it. My Smartthing HUB see only 2 channels. I used Zigbee multi switch DTH.

Aliexpress 4 chanel switch

Any ideas?

Thank you.

You may be the first person to try the 4 channel version with Smartthings.

I would have thought the Zigbee Multi Switch DTH would have worked, but I do not have the 4-channel version yet to try. So, I won’t be of much help in getting it working.

Considering that many our Smartthings community members/developers are actively creating new drivers to replace the current DTHs, hopefully some will take interest in this device, or it will “just work” with the Edge replacement for the Zigbee Multi DTH.

I did see that some indication that it is working with Hubitat, and that is usually a good sign for device compatibility with Smartthings.

Wish I could be more help, at the moment, but this is of interest to me as well. I think the chances of it eventually working with the new Edge drivers are good, for what that is worth.

Thank you for your reply.
Hope that there will be way to succes:-) I would like use this module for connect to exist home automation Jablotron. Zigbee switch will be as trigere connected to input of Jablotron and after that I would like control Jablotron via voice through Google assistant:-)

I’ve tried this with the 4 way switch and it just adds 2 controllable switches in SmartThings. I’ll try and figure out how to modify it to do 4.

This DTH works with the 4 way version


Well, that was quick!

That’s really good to know. Hopefully the DTH will easily be converted to an Edge driver.

Thank you Paul, I tried it and work it well. So, now I can buy another modules:-)

Thank you one more time.

How do I scan for the MHCOZY device using the zigbee DTH in smartthings?

How do i get the device to show up once I added the device handler in ST?

I’ve barely touched any of my Smartthings devices in several months, but everything seems to be holding up.

If I remember right, and nothing has changed with the DTH, I believe the device will be in pairing mode if it isn’t currently paired with a hub. After scanning for a new device it should show up.

I’m not recalling at the moment if the device was automatically assigned the Zigbee Multi-switch relay, or if I assigned it after it was found.

If you are still not having luck getting it to work, I’ll see what I can do when I get back to my devices.

can someone help me, i can’t find the correct DH or i can’t understand why it doesn’t work for me, always single swich.

I’m using @Mariano_Colmenarejo 's Zigbee Multi Switch MC. Edge driver, which can be found on his Beta Edge driver channel.

thank you very much, it works, how do you feel with this device as reliability?

I have used one for over a year, and it has never gave a problem. I give five stars!

One thing, though, sometimes I change the mode to momentary by accident, which made me think it was malfunctioning, but of course I just pushed the wrong button.

thank you very much, i think to use it: 1 channel, electric lock, 2 channel, automatic gate, 3 channel, other electric lock, and the 4 channel of led lights.
