Review: Works flawlessly with deconz - 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. :)
Review: Works as anticipated - 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.

### ⭐⭐⭐⭐ USB port not accessible when cover is in place
*by A***Y on 26 September 2025*

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.
