2 Channel 5V 12V ZigBee Dry Contact Relay Switch, Adjustable Self-Lock and Momentary Interlock Working Mode, Works with Philips Hue, SmartThings, Alexa and Google Home

I'm planning to use this to turn on/off speaker circuits along with my Conbee 2/PI 4/Deconz setup. Powered it via 24V DC, which matches what I need for other lighting controllers. Paired easily showing two on/off switches. It defaulted to the "on for 3 seconds" mode, but pressing one of the buttons let it turn on/off as expected. Pretty instant response time. Both switches work independently and also via a Zigbee group. They even work via Zigbee scenes - so I'll be able to have scenes for "All speakers", "Kitchen speakers", "Dining and Kitchen speakers", etc, which is great. I'm pretty sure Deconz is using Zigbee features for this, rather than faking Zigbee groups. So it's great that it supports the different Zigbee features so well. I've struggled on this with lots of (non-Hue) lighting controllers. It also remembers the previous state, both on/off and mode, after power is cut. I don't know how long for. There's no battery I can see, but there could be a little bit of flash storage on one of the chips. I just bought two more of these so I can control 3x groups of stereo speakers. I considered buying the 4x relay unit which would have been cheaper, but the board looked a little different so I didn't want to take any chances. Now all I need to do is make them a suitable enclosure. :)

Nice little Zigbee relay. Paired quickly with ZHA (Home assistant). Doesn’t have inching, though this is simply overcome in HA with two actions with a short wait between the two. If planning to use 5v USB for power, without a bit of cutting, the case will not fit back on.

Comes with the plastic cover and base attached. You can pry the end caps off but they've not left enough room for the micro USB connection, so you'll either need to cut some of the plastic away or remove the cover entirely.

Flawless with SmartThings hub!

Easy to install. Easy discovery using zigbee on home assistant. Does exactly what I purchased it for. Will be buying more.

Used to control a diesel heater in my shed. Connected without issue and has stayed connected without issue from 15m away. Comes in a nice case and was easy to mount. Recommended

Funciona perfectamente con SmartLife, por fin ya no dependo del wifi!!!!

Works well, however user manual is not clear about the push button use

Used this with Home Assistant and Phoscon (Dresden Conbee)

I use this relay to control a Vevor smart curtain track. They're dry contact relays so it was perfect for controlling a curtain. They sync perfectly with my Zigbee coordinator (Smlight - SLZB06). Everything is controlled in home assistant with ZHA. They appears in HA as light switches, but a cover template resolved that problem. They work perfect for what I needed.

bought 2 of these, the first one is fully functional with Hue, the other identifies itself as one singe relais ( can't access the second relay through Hue ) first one identifies itself as ZB-SW02 .. most recent unit identifies as TS0002 .. it must be a firmware difference
