Xiaomi Mi Smart Plug (New Model) Device Handler

johnconstantelo · June 7, 2020, 8:16pm

Ok, ready for some testing? Since I don’t have one of these, I’ll rely on you for a lot of help.

Create your own DTH using this code:

https://raw.githubusercontent.com/jsconstantelos/SmartThings/master/devicetypes/jsconstantelos/my-xiaomi-zncz04lm-mini-home-smart-socket.src/my-xiaomi-zncz04lm-mini-home-smart-socket.groovy

Before using this, start Live Logging so we can catch any errors.

This should work in both apps. In the Classic app you will see more tiles than you will in the new app. Most notably will be Configure. Since that’s not available in the new app, I created a preference/setting that does nothing but trip configure every time it’s toggled.

To be honest, I’d prefer we test with the Classic app until we’re sure this is working, but I’ll leave that decision up to you.

Once you edit your device to use this DTH, it should initiate configuration, so keep an eye on your live logs for all that, including any errors.

I’ve included a lot of live logging events, so make sure to turn on/off the device, as well as tapping on the Refresh tile (or pull down in the new app). If you don’t see power reporting (watts), tap on the Configure, or if using the new app, go to device setting and toggle it once. You’ll see those events in Live Logging, similar to this:

Can you give this DTH a try and let me know how it goes?

If energy doesn’t show up, don’t worry about that yet. This device reports energy usage over time since it first joined the hub. You can’t reset kWh’s without resetting the whole device and rejoining, so the reset tile does a virtual reset. If you look at your device details, you should see these states:

kwhTotal = usage during the lifespan of the device since it joined the hub
resetTotal = a saved value since the last virtual reset to calculate energy (kwhTotal - resetTotal = energy)

You might want to keep an eye on the ‘Power Consumption Report’ capability to see where that is going.

johnconstantelo · June 7, 2020, 8:37pm

Do you mean cluster 0702? If so, that’s where kWh is coming from. These devices don’t have the ability to reset that value without excluding them from the hub. Just in case someone wanted to reset these monthly, or some other schedule, I did the virtual reset while still saving total lifespan kWh used. Hopefully when we’re able to have custom tiles in the new app, I’ll include it. I probably could add it now so the Classic app show it. That’s pretty easy to do.

OK. I’m not sure I understood absolutely everything in your instructions but here is what I’ve got until now.

I added the device handler
I reconfigured the device to use it
I tried turning the plug on and off
I tried the Refresh button
I tried the Configure button
I tried the Reset kWh button

There were two warnings that came up (I’ve tried to highlight them below) but I’m not sure what caused them. Here are the logs:

Finally, here’s the screenshot of how it looks in the app

And the data on the IDE

That 1.93 kWh is from a previous attempt with another DTH. Power is still at 0W.

Let me know if you’re missing anything or if further testing is needed. Thank you!

orangebucket · June 7, 2020, 9:09pm

No, I meant ST has a ‘Power Consumption Report’ capability that might have potential for handling your kWh total and resetTotal in a standard fashion. You can only guess so much from the JSON though. Not something I’ve looked into myself as I don’t have suitable devices.

johnconstantelo · June 8, 2020, 7:00am

Hmm, ok. It looks like the plug turned on/off based on what I see, is that right?

I was hoping I could easily repurpose another similar DTH I have for this device, but it doesn’t look like I’ll be able to do that. This is turning out to be a lot more complicated than I expected since I don’t have a device to test with.

This is the power reporting cluster, and there are several showing up. Unfortunately the value is always 0000, as you can see in your live logs. Looks like we won’t be able to use that for anything.

There are also 2 other clusters being used - FCC0 and 000C. 000C seems to have to do with power reporting, and FCC0 is a Xiaomi manufacturer specific cluster (source), which looks like that’s where several attributes live:

I looked back at one DTH you tried:

https://raw.githubusercontent.com/bspranger/Xiaomi/master/devicetypes/bspranger/xiaomi-zigbee-outlet.src/xiaomi-zigbee-outlet.groovy

Did that one turn it on/off?

If so, lines 165 and 172 may just need to be tweaked to change the endpoint from 02 and 03, to what this plug sends. Can you try going back to that DTH and change line 165 so that the endpoint is 15 instead of 02 and change line 172 so that endpoint is 16 instead of 03.

It should look like this after those changes:

else if (descMap.cluster == "000C" && descMap.attrId == "0055" && descMap.endpoint == "15") {
	def wattage_int = Long.parseLong(descMap.value, 16)
	def wattage = Float.intBitsToFloat(wattage_int.intValue())
	wattage = Math.round(wattage * 10) * 0.1
	resultMap = createEvent(name: "power", value: wattage, unit: 'W')
	log.debug "${device.displayName}: Reported power use is ${wattage}W"
}
else if (descMap.cluster == "000C" && descMap.attrId == "0055" && descMap.endpoint == "16") {
	def energy_int = Long.parseLong(descMap.value, 16)
	def energy = Float.intBitsToFloat(energy_int.intValue())
	energy = Math.round(energy * 100) * 0.0001
	resultMap = createEvent(name: "energy", value: energy, unit: 'kWh')
	log.debug "${device.displayName}: Reported energy usage is ${energy}kWh"
}

I’m thinking these simple changes may work for you. Can you try? My DTH is pretty much useless at this point.

If you’re curious, here’s my source for that info and why I think that should work for you:

robertash · June 8, 2020, 6:59am

We have power!!!

I did the changes as you suggested. Now I have power showing and running on my automations:

I owed you some answers though:

Yes. Your DTH turned the plug on and off normally.

Yes. It also turns it on and off without a problem.

johnconstantelo:

It should look like this after those changes:

else if (descMap.cluster == "000C" && descMap.attrId == "0055" && descMap.endpoint == "15") {
	def wattage_int = Long.parseLong(descMap.value, 16)
	def wattage = Float.intBitsToFloat(wattage_int.intValue())
	wattage = Math.round(wattage * 10) * 0.1
	resultMap = createEvent(name: "power", value: wattage, unit: 'W')
	log.debug "${device.displayName}: Reported power use is ${wattage}W"
}
else if (descMap.cluster == "000C" && descMap.attrId == "0055" && descMap.endpoint == "16") {
	def energy_int = Long.parseLong(descMap.value, 16)
	def energy = Float.intBitsToFloat(energy_int.intValue())
	energy = Math.round(energy * 100) * 0.0001
	resultMap = createEvent(name: "energy", value: energy, unit: 'kWh')
	log.debug "${device.displayName}: Reported energy usage is ${energy}kWh"
}

So this was the key to the whole thing. Changing the endpoint to 15 started reporting power. It also started reporting temperature for some reason (although I can’t remember if it already did before the edit and it reports 150° without changing at all). Energy is still at 0 kWh but that is not really important for me at the moment. I basically just want to know i the device connected to the plug is turned on or not.

I only have one more question for you. What would I need to learn in order to figure out something like this on my own next time? I guess there are 2 things that are still unclear to me at this point:

What do I need to learn in order to understand everything that the code inside of a DTH refers to and does?
How did the people on the link you provided figure out what data comes from which endpoint? How do they map the data sources in a new device?

This part is just my curiosity so let me know if you know what I would need to learn.

Thank you so much for helping me out!!! You just taught me a lot and saved me from buying a new plug!

johnconstantelo · June 8, 2020, 1:49pm

Outstanding! I was really hoping this would do the trick. Regarding energy, that may only report every few hours, but I also read in other communities where it doesn’t even send a value for some reason. I suspect it could just be a configuration issue. The DTH you’re using doesn’t have a configuration method, which means the device sends data based on factory default settings/configuration.

I started out with the same questions, and through looking at ST’s documentation, their Github code, and other developer code, I learned how to tweak and then eventually develop my own. I’ve done code development in the past, so that also helped.

In this scenario, the device’s “fingerprint” matched most “clusters” of ones that were already in stock handlers, so that’s why I thought some of those would work for you. Once you provided the model, I did a search in Github for it, and found those links I provided above. There are a lot of home automation platforms out there, and a lot of info can be learned from Github besides just code.

There are also a few good Zigbee tools out there that pull all this info out of Zigbee devices (zwave too). I don’t have any because I can usually find what I’m looking for on the Internet.

SmartThings has a few good sources for documentation. One of them is being replaced with newer documentation, but it’s still valid:

New:

Classic: (it’s also the Documentation link you see in the IDE)
https://docs.smartthings.com/en/latest/
https://docs.smartthings.com/en/latest/ref-docs/zigbee-ref.html
https://docs.smartthings.com/en/latest/device-type-developers-guide/zigbee-primer.html
https://docs.smartthings.com/en/latest/device-type-developers-guide/building-zigbee-device-handlers.html
https://docs.smartthings.com/en/latest/device-type-developers-guide/zigbee-example.html

I also used the Zigbee spec to see how a device is using clusters and attributes, as well has how they’re suppose to be used:

https://zigbeealliance.org/

In your scenario, a manufacturer specific cluster is being used, so that won’t be found in that spec. You’ll need the manufacturer’s documentation, which is usually hard to find. That is where those sniffer tools come in handy, and why I keep an eye on those links I sent you. Here are those again, and 1 or 2 more:

https://zigate.fr/le-materiel-compatible-zigate/ (be sure to translate from French). This is a good site for seeing what they documented for clusters and attributes.

https://zigbee.blakadder.com/all.html is also really good. If you find the device you’re trying to debug, I usually click on the “Confirmed working with DECONZ” link to find what I’m looking for. That’s where I found https://github.com/dresden-elektronik/deconz-rest-plugin/wiki/Xiaomi-manufacturer-specific-clusters,-attributes-and-attribute-reporting a long time ago.

Great! I’m always glad to help anyone in any way I can.

robertash · June 8, 2020, 5:45pm

Thank you so much for taking the time to teach those of us who are just getting started! You’re awesome man!

I’ll get to reading the links right away!

Michael_Baatz · June 9, 2020, 6:54pm

Hi
I also have this device. It seems like that, I can connect it to my system without a device handler. Nice Shows up i Smartthings after just a few seconds, when I´m searching for new devices. I can turn it on/off and set timers. But I can´t see power consumption Is it possible in any way to edit the plugs connection to the system?
Thanks in advance

johnconstantelo · June 9, 2020, 8:32pm

To get power consumption, you’ll need the device handler mentioned above and then make the same changes outlined in post #13. Xiaomi does not use the Zigbee spec “cluster” for reporting power consumption, but their own manufacturer specific one, so you will need a custom handler if you want power reporting.

Michael_Baatz · June 10, 2020, 9:56am

Thank you

nu1mlock · June 24, 2020, 12:36pm

Does the device also work with the new Smartthings app? Does it register history or only current power usage?

robertash · June 24, 2020, 1:16pm

It works with the new Smartthings app.

Regarding history, I’m not sure if this is what you mean but I can see historical power readings in the “History” tab for the device:

I can also see it as a graph on the “Controls” tab.

nu1mlock · June 24, 2020, 2:12pm

Yes, that’s exactly what I meant, thank you! I’ll be getting a couple of these. It seems like they are the only cheaper alternative for Samsung’s own plugs that actually show energy usage.

nu1mlock · June 26, 2020, 6:27pm

I just bought three of these and edited the device handle according to the thread (it was included from my previous sensors through Github, so I only had to change the two lines.

It’s only been a couple of minutes (15? EDIT: 2 hours) but it’s not showing energy usage on any of them. How often does it update?

Edit. Hmm, I don’t seem to have the “Power meter” statistic like you have in your screenshots. I only have “Energy consumption” which is at 0W so far (though it hasn’t been long since I added them). The same goes for both Classic and the new Smartthings app.

I must be missing something of course, I wonder what it is.

johnconstantelo · June 26, 2020, 7:14pm

Just double checking, but did you edit the device and change the Type field to use your DTH? Can you include a screenshot of yours?

nu1mlock · June 26, 2020, 7:44pm

Hmm, no I did not. That might be what I am missing. I might have glared over it, as I mostly checked your reply that was marked as “solved”.

Since I already had bspranger from Github (because of my Xiaomi sensors) I only added the device handler for my Xiaomi outlets and then changed the corresponding lines to match yours (changing to 15 and 16 respectively on line 165 and 172).

I’ll go back and double check and report back.

Edit: It was set as “Zigbee Switch Power” as default. When I switched to “Xiaomi Zigbee Outlet” it does indeed show current wattage usage as intended. That did the trick! Thank you @johnconstantelo! You just made my weekend!

nu1mlock · June 26, 2020, 10:42pm

sigh

After changing type to “Xiaomi Zigbee Outlet” two of the three outlets do show current wattage, while the third does not. It has the same settings and has been changed to the same type. It’s been on for at least a couple of hours now, shows temperature (which I ignore since it’s at 130 Celsius) but does not show wattage. I have a “dumb” meter connected to that same outlet which shows just below 600W being used, yet the Xiaomi outlet doesn’t show any wattage usage.

Here’s a screenshot of that device (it’s a large screenshot, so I’ll host it at Imgur): https://imgur.com/a/b7W5OeZ

Here’s a comparison to one of the working ones: https://imgur.com/a/NqFu0fm

Any ideas?

Edit: Another sigh because it now works after unplugging it and back again. Problem solved, I hope!

Edit 2: While I’m here, does anyone know if it’s possible to somehow show the wattage usage as “default” among the tiles instead of it showing as a outlet that I can turn on and off?

While not optimal of course, I am using these as “smart energy meters” and they will always be on, so I don’t need it to show up as an actual outlet that I switch on and off from the tiles.

robertash · June 30, 2020, 7:36pm

Good that you got it working! Also, nice surprise to see Swedish on your screenshots

I’m using it for the exact same purpose and would also like to do that.

So I have researched this before because I also have some Aqara temperature/humidity sensors that display humidity by default and I would instead want to show temperature on the app tile. I couldn’t find a way to do it in the new app and I am trying to stick to that as much as possible so it doesn’t hurt as much when Samsung cuts the Classic app, whenever that happens.

However, there seems to be a way to edit the default tile metric on the Classic app but I haven’t tried it myself. Maybe you are OK with using the Classic app so here’s the link to what I found, if you’re interested:

Hope it helps. Lycka till!
