This image is the same as my wiring diagram.

While he is working on testing that, can we have a quick conversation on these products. Have you figured out the corporate and/or manufacturing landscape of these Tuya and MHCOZY devices?
Tuya is the umbrella right?, MHCOZY is just one product, and there are multiple entities making the MHCOZY products thus the myriad of designs/instructions etc. ?
Not asking for a Thread Hijack, just one post reply on what you have figured out. Thanks.
I pulled the switch out of the wall and checked the wiring. It all looks good. I shorted s1 and s2 with no effect. That would be the same as flipping the toggle switch. However, I have not removed the device from Hubitat. Deleting the device and resetting it to factory is the only way I know of to remove it from Hubitat. I can try that next.

The answer requires a long reply...
Shortly - my understanding is that MCHOZY is a reseller, they are not manufacturing the products they sell.
Tuya is not an umbrella for resellers and real manufacturers; Tuya provides the tools for developing the IoT products and the cloud infrastructure. Tuya makes money from the manufacturers for the use of their development platform, and for the use of the common 'Smart Life' mobile app, which makes it possible to design, develop, and certify with Tuya a new IoT product in just a few weeks, instead of months or years.
Tuya is also the hardware manufacturer of the Zigbee or BT or the WiFi modules, that are used by the real manufacturers to make a sellable product. They provide the Zigbee or TCPIP/WiFi library for the communication. Then the manufacturer adds an 'application' - what makes the product work as a switch or as a bulb, or as something else.
Tuya also probably produces a limited number of end devices - the Tuya Zigbee hubs may be an example.
What become clear for me in the last month, is that the new Matter Bridges labeled 'Zemismart M1', 'MOES Matter Bridge', etc, etc... are not products entirely developed by Zemismart or Moes. Probably, Zemismart/Moes have ordered the Matter bridges to Tuya with their logos and their plastic box design, but one thing is clear - neither Zemismart nor Moes are controlling the application software inside the bridges. In the beginning, it has been the Tuya software engineers who have converted some existing Zigbee devices based on the Tuya platform to Matter. At the moment, whether a new Tuya-based Zigbee device will be exposed via the Matter Bridges depends entirely on the manufacturers. And now we have the curious cases, where old Zigbee devices are exposed via the Metter bridges (because this has been done by Tuya during the 'certification' of their Matter gateway one year ago), but newly produced devices are not exposed via the Matter gateway - probably because there is no interest / no understanding to add this functionality from the companies, that order and sell the products .

I deleted the device from Hubitat and then reinstalled it. I did not restore it to factory specs, I don't know how to do that. When I paired it back with Hubitat, it used the Zemismart driver. Still no change when I short s1 and s2.
It may be a defective device... It doesn't make sense to produce a switch module that can not be manually controlled by the wall switch.
The different switch modes are for the type of the switch - whether it is a rocker type or a push button (a spring returns the switch to the default position). The third mode determines whether thos on/off state of the relay module is flipped by the mechanical switch or is always on when closed and off when open.
Thanks for all the help. I think I'll send this device back and try a different brand.

My question and this through reply probably belongs somewhere else as it encapsulates answers that others may have about this whole bundle of products. I'm just not sure where.
Thank you.
There are mixed reviews on Amazon but clearly somebody in this Community has it working.
This is the trouble as I see it with this whole cadre of MHCOZY products, they are priced really well and are conceptually good stuff.... but it seems like you: a) never know if you have a dud in an otherwise good product line, or b) a mis-designed product, or c) some software bug or incompatibility that is about to be fixed in the next one you buy.
You raised my interest in this new module which I had not noticed before. I have some of their relays working like workhorses for going on 2 years now I think. So I would never say that they are across-the-board junk. But it seems the model, version, source, and other labeling is material to smart buying of this stuff.

Some of the MCHOZY brand devices were probably manufactured by Sonoff (or from the same manufacturer, that makes devices also for Sonoff 
)
These are identified by a Zigbee manufacturer ID 'eWeLink ' and typically follow the ZHA 1.2 standards and they all work with HE inbuilt drivers.

Here's a shot in the dark, I have a zemismart device and it behaved very badly with LED bulbs and only wanted to function correctly with a larger load, so I had to change 1 LED bulb for an incandescent. Once I put that incandescent bulb in, the switch was perfect. So if you happen to have an old floodlight or one of those , now illegal(assanine), incandescent bulbs you could try that. Or try multiple LED's or even an old fluorescent bulb, anything that draws more power in the circuit. This problem is typically seem with no neutral type switches, however mine was a dual load Zemismart switch, with both line & neutral connected.

I guess it's possible that the load is too small. I have 6 LED shop lights running. That should be somewhere from 48 to 78 watts. I don't know what the minimum requirements are for this switch.
That should be enough, it took only a small 40 watt incandescent bulb to get mine running. You could try, if possible, to introduce a slightly larger load, maybe a floodlight
Got the new zigbee switch today. Sonoff zbmini and its just as small as the Mhcozy.
The main difference is that the SONOFF WORKS. It even uses the standard driver.
Man do I feel better. I want to thank everyone who assisted me with this. You guys are good people.

That is a pretty slick image. Would you mind giving a hint as to how you do that?
It's always great when there's no-fuss to getting a product to do what you expected it to.
Can you relay what the price difference was if any. Thanks
Amazon
Sonoff switch 14.79 plus tax
Mhcozy switch 15.90 plus tax

Just posting to show the continued variability of data showing up on these. Just received this single channel module yesterday. Paired in an eyeblink. Using Generic Zigbee Switch driver but that might change shortly.
