Easy to set up and gets recognised instantly when I tried to add it in home assistant. Also seems to be acting as a Zigbee repeater, so might be handy to have if you want to extend your coverage.

5.0 out of 5 stars Works perfectly.
Reviewed in Canada on 23 October 2023
Verified Purchase
So I bought this because I'm an old curmudgeon who likes his old school mechanical doorbell and wanted to keep it while using a nice new video doorbell that wanted me to plug in some awful digital chime.

Enter: this thing. It successfully runs off of the power from the transformer the mechanical chime is on. I wired it up to the chime and powered it off of the chime's transformer, and then wrote a homeassistant macro to fire it when someone presses my doorbell.

And voila: mechanical doorbell chime on my digital home assistant configuration. I'm pleased. Setting it up was laughably easy and literally took about 5 minutes.

And I was prepared to buy a bread board and a bunch of components and solder something together. to get what I wanted.

5.0 out of 5 stars Works with Home Assistant for automated garage door opener. Instructions are poor.
Reviewed in the United States on 30 December 2022
Verified Purchase
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.

5.0 out of 5 stars Perfekt für meine Heizungsanlage
Reviewed in Germany on 12 January 2024
Verified Purchase
Ich war zuerst etwas skeptisch. Betrieben wird das Relais an einer großen Industrie Heizungsanlage. Das Problem war, das bei längerer Standzeit der Gasheizung der Gasdruck sinkt und die Anlage auf Störung schaltete. Also eine PTZ Kamera zur optischen Überwachung der Störungslampe installiert und das Zigbee Relais verbaut. Schön ist auch, das man von permanent auf Taster umschalten kann. Genau das was wir brauchten, denn das Relais ist potenzial frei. Ab sofort können wir die Störungen der Heizung aus der Ferne beheben und müssen uns über gefrorene Wasserleitungen keine Sorgen mehr machen. Super Teil und funktioniert mit dem Philips Hue System einwandfrei. Kann ich nur empfehlen.
