Smart Home Dry Contact Zigbee Relay Switch, Remote Control Zigbee Switch for Light Garage Door, Compatible with Alexa Google Home,Zigbee hub Needed (1CH)

I got this to open and close my ancient Genie garage door opener remotely. The garage door opener is hard wired to my wall switch, so I knew which wires needed to be 'closed' when the switch is pressed. Wiring it up was no issue at all.I could pair the unit just fine, but for the life of me I could not get HomeAssistant to activate it.1) After an hour of fiddling with it I changed the USB power cord and wall charger power source to a different one and it worked perfectly! So check you have enough juice getting to it even if it pairs but doesn't work.2) HomeAssistant sees this as a 'light' device and not a 'switch' So ...Edit your configuration.yaml in your HomeAssistant config directory and at the end, add something like this:zha:device_config:a1:c7:38:da:d1:f8:52:21-1: # format: {ieee}-{endpoint_id}type: "switch" # corrected device type(change device ieee ID to your's as shown in HA device config)Restart HomeAssistant.Then voila it works! Paired with a garage door tilt sensor you can do some fun automatons.As another reviewer said, it had 2 modes ... 1 mode makes electrical contact for 1 second and one mode its always on when activated, so you can work with that accordingly.

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 devicesMy 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 codezha:device_config:84:71:27:ff:fe:93:17:24-1: # format: {ieee}-{endpoint_id}type: "switch" # corrected device type###Ending Zigbee configuration codeAfter 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.

was super easy to setup and use with Home Assistanttook 12volts off the battery charging unit inside the gate box.

Nice functionality for the price. Tested it successfully with power applied to the micro USB jack, and with12V DC power at it variable power port, and it worked fine on both. It will be used with the 12v power, replacing an RF only activated replay board. It was easy to initiate Zigbee pairing and get it integrated into my Hubitat Elevation Home Hub. Switching between switch modes is easy (perhaps too easy) with the simple press of the mode button. To protect the board from spurious contact and the creation of 'magic smoke', I 3D printed an open-ended case and top. I set it in simple switch mode and use HE's automation routines for the channels requiring timed latching.The 4 Channel board had been sitting idle for 72 hours as I typed this review, so I tested it, and all channels responded to activation, so it does not suffer from the quick idle lock issues I have seen in some other Zigbee devices in as little as 8 hours of idle time. I do not specifically need the Zigbee relay feature of this device at the install location, but it is certainly a nice to have.I expect to buy more.

The media could not be loaded. Works perfectly for local control of a garage door opener. An alternative was needed, since Genie broke the Aladdin api. This is even better because it no longer requires the cloud, or an extra app on my phone. This relay stays consistently and reliably connected. It did not include any instructions, but they're available on the internet. The habitat setup took a little trial and error, finally settling on generic zigbee switch. I'm monitoring state with a basic magnetic door switch. It works great with Alexa to check the state and open and close the door.

Paired easily with the Phillips Hue hub as a light. Very responsive and does not require an internet connection to control. I now have 5 of these installed; 1 outdoor connected to a set of 12v lights in a water tight box. This one is about 50' away from the hub where the temperature ranges from 0F to 100F and the power cycles with the outdoor transformer dusk/dawn. It works perfectly every time. 3 other 12v are used to provide relay to wires soldered to a Somfy automated blinds remote control. Open, Close, and "My" (custom) blind positions. The 5th one is the 220V model to control the gas fireplace. Power is supplied via the fireplace "Aux" plug and the relay is hooked to the low voltage wall switch wiring. All respond quickly via Alexa commands.
