Review: Works great, nice to have a good DC combo option - Works very well. Four relay channels, each have their own isolated common, NO, NC lines, which do not have to be fed by the same source. The controller itself may be powered with either 5v via μUSB, or variable DC u(7-32v) supplying a switching regulator cluster onboard. The relays can operate in three mode types, latching (switched on or off, remains until commanded otherwise), a pulse (momentary on for a second, then off), and a third mode I haven't nailed down yet because I don't have a need for it (and documentation is ambiguous). Each channel may operate independently as independent devices on most hubs, AFAIK. However, installation/pairing will probably be slightly outside of what most users expect, and the documentation is very limited. For Hubitat, which is what I use as my core on a very large multiprotocol network, this took some time until I found some information on a dark corner of the web. This is non intuitive: Pair the controller as a whole, change the driver to generic multi endpoint controller type, the child devices should immediately self-enumerate. If you do not change the driver, there's so.s very confusing results. I don't think it's worth it to even try to operate the controller as a single unit with complicated addressing (or if it's even possible that way). After you have changed the driver and the hub core recognizes the four endpoints, there are still some flags that can be sent to the parent unit for various things, but I have not looked into it. Once this is done, treat the four child devices as their own standalone switches, and you're set. You can change the base mode by pressing the mode button on the unit. I'm keeping this set as latching on/off, and I'm using the four channels to control zone lighting in my office. Probably all 12v, from a common power supply for all of the LED lights and the controller. I may opt to use 24VAC instead, but for anyone reading this, keep in mind, this is NOT the AC controller as far as powering the controller itself. You can run whatever you want within rating of the relays for each channel, but the controller MUST be red with DC. Fair price, looks to be of good manufacturing quality, looks good all around. I may get more.
Review: Works with Home Assistant for automated garage door opener. Instructions are poor. - First of all, this is a nice zigbee relay for a fair price which was delivered quickly, I do recommend it. I bought this to automate my garage door using Home Assistant and it works great. The device identifies as an eWeLink ZB-SW01. Mine came with a case which was a nice surprise (received on 12/29/2022) The instructions were nearly useless, not completely useless because they did help get the fire going in our firepit. Despite the poor instructions, it paired with my Nortek HUSBZB-1 stick instantly and is very responsive. The relay was in "momentary" mode when I got it so no changes were required. I am using the USB input for power which is very convenient. The relay's I/O has 3 terminals: a Common in the middle, a normally closed on the right, and a normally open on the left which is what I used with our old basic genie garage door opener. The relay is toggled for a default of 1 second when in momentary mode is selected which I think they are referring to in the product description as function 1 "inching" (what the heck is "inching"?) as seen here: (From original Product description) Function: 1. Default inching Function: Press the open relay by mobile phone, then cut off the pull-on immediately(default one second) 2. Self-locking mode: trigger to Turn on/off connected devices My interpretation of this would be- Function: 1. Default - Momentary mode: When triggered, the relay will operate for 1 second and then reset to its initial condition. 2. Toggle mode: When triggered, the relay will change states and hold until the next toggle command is received. This device paired very easily, I simply initiated "add a new device" in home assistant and it found the relay without any interaction on my part; it did add the device in the domain of "light" rather than "switch". There are a few workarounds for this, I chose to add a small bit of code to my configuration.yaml as follows (using the IEEE value of your device in place of this example)- ###starting zigbee configuration code zha: device_config: 84:71:27:ff:fe:93:17:24-1: # format: {ieee}-{endpoint_id} type: "switch" # corrected device type ###Ending Zigbee configuration code After adding this to configuration.yaml, reboot home assistant and then go to the zigbee integration and open this relay device. I found that the original device was still showing in the middle of the page under the CONTROLS section but in a state of error stating something like "this device is not longer available to zha...". The new "switch" device was now present under the original "light" device so I simply opened the old failed light device by clicking on it, chose the settings tab from the popup window, and then delete down in the bottom left. Now everything was exactly the way I wanted it and I was able to utilize the "switch" in my garage door automation.

### ⭐⭐⭐⭐⭐ Works well with Hubitat Elevation C-8 Pro
*by M***K on October 29, 2025*

This 4-channel Zigbee relay was easy to install, I'm using it to add remote control to overhead doors in a multi-car garage. It installs like any other Zigbee device. After initial installation navigate to the Hubitat "Devices" menu and change the device driver to "Generic Zigbee Multi-Endpoint Switch" to make the four relays accessible as individual switches. Unlike the WiFi relay I was using previously with Google Home, this one does NOT close the relay (and thus open the doors) when power comes back after a power failure. I'm very pleased with it.
