Do u have an aqara hub that's updated to matter yet ? If so then you can use it already

Oh I assumed you have a matter  updated Aqara hub paired with a Matter Hub . Without the matter hub (Alexa / Google nest or Apple Homepod) , it won't work.

My nest minis have been updated to matter based on the firmware number. Just haven't hopped on board the matter architecture for Homekit yet.

You need a Google nest mini. U can get one at shopee now for about RM100 after using their coins cashback voucher. Then you connect your aqara zigbee hub to Google home via matter and works with Google then connect the Google speakers to the same "home" using Google home. Then connect tuya to Google home using works for Google.

Basically everything in 1 home, then it will just work. You need spend time to rename all the sensors and D1 switches though. Then you add those switches to the right home and room. Then u can use the automation lo.

Eg. When aqara door sensor shows room oor is opened, then turn on room light which is using tuya cheapo switches.

There's not much options for now, but it's a start

Oh if China hub then you need wait until aqara release more updates to support the switches. So far matter only works for sensors, need wait for switches.

I'm using global version hub, connected to "other" region so my switches can connect to Google via "works wirh Google" so it will appear. You can try choose works with Google and choose China mainland server see will appear or not.

There is even 4 gang, sweet. Is the back deep? Like deeper than D1?

BTW did a full migration from Aqara to Z2M and i would say i am pretty pleased, although its no where as close to being noob friendly using the manufacturer hub.

Even started over my HA, now move to docker instead of vm, so far so good.

You can use some 3rd party app to back up everything and when restore you can easily get back most stuff.

Can't be sure tho, mine is China version I bought 1.5 years ago though ,but is China Version and it connects to global version aqara hub. What's important is the hub must be global version, but some say here even the Child device region lock so I'm not sure haha try ur luck. But I can give you the model number.

Door window sensor mccgq11lm
Cube mfkzq01lm
D1 switch QBKG25LM
Pir motion sensor with lumen RTCGQ11lm

All these are China Version not global version. All connects fine with my global M1S Gen 1 hub that supports Google home. Now it also supports matter via Google Nest mini as matter controller. I can use the sensors to trigger other devices connected to Google home via "works for Google" too like tuya switches and smart plugs

The m1s hub can connect using mihome app too and all the aqara child devices works even when change region to Malaysia instead of China. But it won't run locally it will run online so if your wifi down it will not work and of course will got some delay as it connects to the server. The automations also not as good as aqara app. That's why I use aqara app and abandon mihome, luckily I only got xiaomi cctv and vacuum robot which don't need any automation. If you have yeelight that one can connect to Google home so no need to use mihome.

If you using mihome and have issues with region, you can Google for a unlocked mihome someone on YouTube will teach where to download. I have the hacked mihome too and it works, my vacuum robot is actually China version and not support Malaysia server, but with the hacked apk I can use it via Malaysia server and response time is much faster.

Aqara if using Aqara app everything runs locally. Same with when integrate with matter. So no need connect to China.

The top is fully covered, and tbh if the rain is not pouring at a crazy angle, its hardly going to get wet. I was kinda surprised by that as well, in fact it didnt even die, i was like its already 3 years might as well change now LOL.

All routers will extend the range, so lets say you have an Aqara switch that will extend it, your motion sensor is an end device, its not a router so it wont extend it regardless of youre using the sonoff or your Aqara hub. If using Z2M way, pair all the routers first (switches) then only pair the end devices, and i would recommend pairing the end device to a nearby switch/router rather than coordinator, Aqara sensors pair best with Aqara switches.

No it wont, but if youre running 2 seperate zigbee networks its probably going to interfere, i suggest selling off the M2 and switch to Z2M fulltime when you do decide to get other brand zigbee stuff until then just continue getting Aqara stuff i guess, i did that. I used to use the M2 with that same integration also, also had Hue hub and then sold all the hubs and just change to Z2M. And regarding not getting certain status usually the homekit integration is the one that will report less stuff.

What do you mean by that yea? In HA what does it show?

In Z2M this is what mine looks like.

Yea thats me also LUL

No idea about your last question.
