Anyone know how well this works with repeaters?
I've found it to be fabulous

Can you clarify what you mean? If you mean does it work well as a repeater, then I can answer that. Here's a zoomed-in view of several devices routing through this relay (in zigbee2mqtt).
Also tagging @ogiewon. Here's another device that works well as a relay for Aqara devices with zigbee2mqtt.

Perfect! Thanks!

I am powering one of these off a 12VDC battery that is recharged by a solar panel.
There is a Controller in the circuit that will shut off power to downstream devices at a set-able threshold.....but boy it would be nice to see the voltage being fed to this RELAY so I could remotely know the state of that battery on any give day of solar charging. Wonder if reporting the DC Voltage is within it's capability.
Checking to see how this 4 Channel relay is doing for you (or anyone else)?
I've tried the 2 Channel and with HE driver improvements the 2 Channels get recognized and work as hoped. (Thanks @mike.maxwell ) Nice step up from the 1 Ch.
Any reports if the outcome is the same with the 4 Ch version?
You all know how it goes, dip one toe in and you're buying the 1 Ch, dip your foot in and your buying the 2 Ch, ...finding the reliability & function of these things to be what it is....you're putting your whole leg in wanting to buy the 4 Ch.
it should be, I have the MHCOZY 4 channel unit running in production...

Hey there,
can't tell you anything new. I started a new job in January and had absolutely no time to tinker with anything. 
But I'll keep you posted. 
Hopefully should know within a week or so. Just waiting for mine to get here.
Is anyone else seeing that the "manufacturer" of these is differing as you get into the 4 channel models or did I just get somebody copying/knocking off the original concept?
- endpointId: 01
- application: 50
- softwareBuild:
- inClusters: 0003,0004,0005,0006,E000,E001,0000
- outClusters: 0019,000A
- model: TS0004
- isMultiEP: true
- manufacturer: _TZ3000_excgg5kb
Also, I see more that four "children" showing up, EP01-EP04 and then EPF2 which I have not figured out the function of yet, it yields no ON/OFF/REFRESH response on it's device screen.
State Variables
- epList : [01, 02, 03, 04, F2]
Lastly, while you get different device screens for each child it is a shame you can't change the LABEL to something besides the cascading default of: "what you called the parent upon joining - EP0x" @mike.maxwell is that something within your control ?
every version Tuya makes for a different customer has a different meaningless manufacturer name, they are also jchanging the last endpoint that has no function, and we don't create children for specific ones, I'm not going to be able to keep up with all the different versions of these devices.
its actually under your control, you can change the name, the label, or both.

Manufacturer - got it.
Device Name & Label - whoops, user oversight ! I can indeed change the LABEL in the associated field on the child's device screen. Can't change the "child's" default device NAME but now that I see I had overlooked trying to change the LABEL I don't need to. Sorry, I just whipped right into trying to change the device NAME.
Thanks

I bought this unit and have been trying to connect it to Hubitat Elevation. No luck. Do I need to have the tuya app? I hate to use Chinese apps because I don't know what information they are sending back to china.
Did you purchase the zigbee version? Or the WiFi version. Only the zigbee version works with Hubitat.

Manufacturer shows the same on mine.
I don't know what the F2 child device is either. I just used the 4 relays.
F2 is the endpoint of Tuya's Green Power cluster implementation.
I have no idea why Tuya is exposing it, as It is of absolutely no use for the DC powered relay controller. Can be simply ignored.

Step one would be to clarify which module you got.
If it's the ZigBee series we have all tried then we need to learn what you've tried and where it's hanging.
This amazingly has been one of the easiest no-name devices to join AND STICK relative to some other named devices we'd EXPECT to be easy and aren't.
I'm going to reply/post on this post with a Use Case topic because @david4 has the picture right there and has made the most recent complete post on these devices (and you guys following this thread seem to care about the applications thereof).
So, here's my objective.
To control a 12VDC (less than 1amp under load) actuator which when wired and powered in one polarity will extend to the point of the internal fully extended limit switch. When wired and powered in the opposite polarity it will retract to the point of the internal fully retracted limit switch. These are typically set up with DTDP relays or just a momentary rocker switch that powers -/+ in one throw and +/- in the other.
I have one of these devices ( the 4 relay version) in a location where I am using two of the relays and I am wondering if I could safely use the other two relays to achieve this polarity reversal control of the actuator.
So I'm thinking (out loud) that I'd wire the + from the battery to the COM on one relay, and the - from the battery on the COM of the other relay (actually there is a solar panel controller in there, this isn't really going direct to a battery).
Then using the Normally Open and Normally Closed of each relay I'd achieve the polarity reversal capability depending on the state of the relays, ON or OFF. On paper it seems to look like it might work if there were no inrush or other transitional switching issues. I have to work through the logic again because I'd rather not send power after the limit switches have been hit. That might just be a timing thing to work out because I either want the actuator fully extended or fully retracted, no in-between.
Someone that works with this stuff all the time might be primed to say- "no no no, that's going to cause issues or fry something, this is what you'd use to to achieve this". I'm waitin to hear that if so. Thanks in advance.
EDIT: Refering answers to this to another thread specific to this problem.
yes, Bought the MHCOZY 2 channel ubit. I think it's the zigbee version.
