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: Straightforward setup - I used this to add my sprinkler valves to HA. Being able to power the relay off of the same 24VAC sprinkler transformer was very very convenient. I'll update this at the end of the summer to double check that it's still working well. I was able to add it to home assistant/zha without any issues. To change the channels to be detected as normal switches, I had to add the following to my configuration.yaml: zha: device_config: id-1: type: "switch" id-2: type: "switch" id-3: type: "switch" id-4: type: "switch" Where `id` is is the zigbee address listed under device info in home assistant, LOWERCASE. If it's all caps in home assistant, change all the letters to lowercase in the configuration file. That was an issue I had and this didn't work until I changed the letters in the address to lowercase.

### ⭐⭐⭐⭐⭐ Works great, nice to have a good DC combo option

### ⭐⭐⭐⭐ Reliable 24 V Valve Control. Functional but Imperfect Integration
*by N***S on May 9, 2026*

Works with Home Assistant ZHA, though it shows up as 4 lights instead of 4 relay switches. If you don't want the relays to appear as lights in Home Assistant, you have to edit your configuration.yaml file to override the device type. Annoying but manageable. I use this 4 relay device to control 24 V AC sprinkler valves. It's been working reliable for over a year now. It would have been 5 stars instead of 4 if it weren't for the device mis-identifying itself as a set of lights.
