I'm still getting these 2 messages Everytime I try to link my Mi Home and Yeelight to Google Home zzzz

Just received my tuya zigbee switches and gateway. Going to try them out later tonight.
I bought only 2 switches. Just to test them. If success.  Will order the rest of them..

Wish me luck.

Probably that area is near a Wifi/Zigbee dead zone? How is the wifi reception there? Slow, hard to connect......etc?

Is the 3 gang switch and water heater switch at the same location in the room? If you're at the very edge of your wifi network then that could be why. Same thing with zigbee, if you're on the very edge, it could be why some devices are connecting and the switch isn't (plus neither of the sensors will function as a repeater).

But given that you're facing the same issue in the same rough timeline with both the wifi and zigbee switch, it's most likely a wiring issue. Double check your neutral cable especially.

Edited: If you happen to have a zigbee repeater on hand, stick one nearby and see if it helps. At least then you can rule out coverage issues.

im not sure about the internal differences between these 2. 

but  i can say that the UK type looks bigger.  i dont think it can fit in our MY switch holder??

Should be fine, I got one EU wall switch I think. Fit nicely.
Just don't go buy US type, wrong voltage and size. 

Not all rooms are same and equal.
I have a room with L shape in which 3 corners have good wifi coverage.
The other corner which is at the long handle of the L have spotty wifi/Zigbee but is manageable.
And i have tested it using the Wifi Analyzer app and a Zigbee motion sensor to prove that.
So, unless you have ruled out coverage issues, I don't have an idea what could be real cause there

Is your 20A Zigbee double pole?

The zigbee 20A switch is same brand with others? 

Do they even make double pole smart switches? I don't think I've ever seen one.

NVM, apparently most if not all the 20A smart switches are double pole. I'm just dumb. lol

This bloody thing still cost an arm and a leg, how much you got it for?

But only switch on? How to off for your heater?

Just sharing

The dimmer switch doubles up as a zigbee signal extender/repeater 😁

Thanks Agathon for your sharing, it really helped me a lot in deciding whether go for Aqara switches.

Since I am not tech savvy and thinking of going ecosystem that support Homekit, so most probably I would bite the bullet and go for Aqara switches.

There are list of items that I going to purchase. Do you have any ideas what's more to add to complete the package?

Aqara Smart Lock D100

Homepod Mini
Aqara Hub M2

Thanks in advanced 

Currently planning for renovation so might be changing the existing glass sliding door. By the way anything need to take note or caution with this door lock? Or you have better recommendation?

Yes I believe there is one and would definitely check it out and see whether able to save some bucks from doing so..

This year completed my mission of converting entire house to full TUYA'ed!

Yes there is, and it's actually maintained by a Tuya dev team as well. But the official Tuya integration is still fairly new and whether it supports your particular product can be a bit of a hit or miss.

The integration so far works with my wifi smart plugs (the cheap, brandless RM30 ones from Shopee), Zemismart Wifi roller blind motor, and Toush 2-gang zigbee switch (without neutral).  My door sensor doesn't show up at all and my motion sensor just works wrongly (the state doesn't reflect the actual state in the Smart Life app). Tuya's IR Blaster isn't supported at all so I had to switch to Broadlink (using a RM Pro but I've also used the RM Mini 3 as well) - used to control my AC and TV.

I guess gotta wait a while before everything is supported properly.

Still, I've got all the major devices working on HomeKit and that's 90% of what I wanted out of switching from Alexa/Google anyway. An added bonus is that Homekit doesn't need a Nabu Casa subscription (or the hassle of setting up the workaround).

Fiddling with Home Assistant can be fun. I just recently figured out that I can set up my IR commands to control my TV as scripts rather than switches so that I can ask Siri to turn the tv on/off and change inputs without having to deal with switch states.

Now just need to wait for the tuya integration to work properly with my sensors and it'll be perfect.

Thanks for your advice. My house is 3 phase, so it seems this project will be more complicated than I anticipate.. would it be better to just opt for no neutral switches? (Aqara D1 and the likes..)

Hahahaha, u got me!
"*$W&#&*#! Why it turn off by itself and turn on by itself, hah?! You think this house is disneyland!" <-- already numb.
