Hi, I’m looking for a solution to control (eg on/off, dim, etc) lights at home for an upcoming reno project at HK. Most dealers here are selling Control4 based solutions which is bloody expensive. Given I only want to control my lights, view IP Cam feed, etc I figure the Smart Things Hub would work just fine (let me know if I’m wrong on this). However I am unable to find any compatible switches / wall dimmers listed that works with 220V AC. Any one knows if 1) SmartThings is available (officially) here in HK? 2) Which brand / line of 220 V AC switches / dimmer are available that’d work with Smart Things? ---

So far SmartThings is only officially available in the US and the UK. And maybe Canada, which uses the US version. This introduces an immediate problem, as Zwave operates on different frequencies in different geographical regions, and the frequency for Hong Kong is different from that of both the US and the UK. In some countries it is illegal to use a zwave frequency not specify for that region, as it might interfere with the band reserve for ambulance communications or something else of public interest. > [@FAQ: SmartThings international function](https://community.smartthings.com/t/faq-smartthings-international-function/14898): > > Hello all. I am fairly new to the HA field, and I have been extensively researching and settled upon smartthings as my number 1 choice for a smart hub. However, I live in the Caribbean and I am just curious about one thing in particular. I realise thst there are US, UK and other z-wave frequencies etc. so my question is : if I buy a US version of the smarthub and all US accessories (sensors etc), will it work even though I am outside of the US? I know that buying UK “Things” won’t work with a US hub, so I’m just curious. Do I need to be literally in the US or can I just buy all US components and expect the system to function as advertised. EDIT : Also where I am from, we have the same specs as the US (110-120 v 50-60 hz). So the first thing you need to do is find out if either the UK or the US zwave frequency is legal to use where you are. (In part because of these legal restrictions, the zwave frequency is set at the time of manufacture, and cannot be changed afterwards. ) if only one is legal, that tells you which model of the hub you need to get. **Selecting Light Controls** The biggest issue with switches is usually the question of whether a neutral wire is available at the switchbox. Most home automation switches, although not all, use the neutral wire to power the home automation radio in the switch so that it will be able to hear the next “on” command from the network even though this switch appears to be off. However, while it is pretty common to have a neutral wire at the switchbox in the US, the same is not true in other countries. So you will see a lot of discussion in the UK category over " two wire" (no neutral) and “three wire” (with a neutral) switch box setups. As far as specific options , see the UK lighting FAQ for discussion of the various standard options for 220v. > [@VFAQ: Lighting Control Options for UK SmartThings](https://community.smartthings.com/t/vfaq-lighting-control-options-for-uk-smartthings/26252/): > > There are many forum discussions of possible lighting control options for the UK. Before we get too theoretical, I just wanted to do a quick recap of the options that are available right now for those in the UK. 1) Choose one of the inside-the-wall micro relays from the official compatibility list and have it installed on the circuit where there is a third wire. Even if there isn’t a third wire in the switchbox itself, there’s still one on the circuit somewhere. It may be at the ceiling fitting, it may be somewhere else in the wall, but it is there. [https://www.smartthings.com/uk/compatible-products](https://www.smartthings.com/uk/compatible-products) If you want to add a new faceplate to create a push button “momentary switch,” you can modify many switches to work with the in wall relay. Plastic button front plates are quite… **Zigbee Profiles** With regard to zigbee, it is important to note that there are a number of different zigbee “profiles” and they do not all communicate with each other. Smartthings uses the “zigbee home automation” (ZHA) 1.2 profile. Devices which are also actually certified for that profile are the ones That have the best chance of working with SmartThings. Zigbee devices are very popular in China, but many use a proprietary form which will only work with that brand, and others use zigbee green power or other profiles which will not work with smart things. This also happens in the US. For example, control4 uses a proprietary encoding which does not work with SmartThings. Often these devices will pair to smart things as a “thing” but then cannot be controlled or lose connection every few hours and have to be rejoined to the network. You can find much discussion of this in the forum under threads dedicated to some of the inexpensive Chinese brands like Xioami. (The smartthings hub is one white plastic box that includes both a Z wave controller and a zigbee Coordinator. ) ---

Hi thanks for the info. So … best thing to do is wait for a version that’d work in China (mainland & HK). Is this on the roadmap for SmartThings? ---

I’m in Singapore & I’m using the UK hub, of course UK version of Z-Wave switch. It should be fine for you to use the UK version. ---

Hi can you let me know which model of switch are you using? I need dimmer switch as well that can be controlled / dimmed from more than one locations. Same for regular on / off switches. ---

Okay aside from Aeon do we have any other brands that also make products for 220V except Control 4 which is bloody expensive? I tried searching online but most if not all I found are 120V. ---

Hi @tamttt , I live in Vietnam, too , and of course on the same boat. As you said above, if you use Aeon Labs’s dimmers working with 220v, could you let me know what kind of hub are you using? I’m going to buy a Eu smartthings hub which uses Eu z-wave (864,) and some Aeon labs’ dimmers which also use Eu z-wave (864,) and support 220v? Is that okay? Pls let me know which Hub and which Aeon Labs dimmers you are using. That should be very nice of you if you give me its model number . I’m now just like a boat bloating on the ocean without a compass ☹ ---

I am on the same boat in HK. I have US smartthings hub. I picked US version simply because there are there are soooo many products that fit US frequency. However, for such simple electric on/off operation (maybe status update with hub) I couldn’t find any. ---

In my opinion, instead of using wall switches and dimmers ( these are not working with 220v yet), you should use Philips Hue lights bulbs and brigde or osram lightify ( which are available in UK store and definitely work with 220v and ST hub). ---

I am constantly trying to find wall switches. Because in a household where my wife prefers the traditional switches and not as tech savvy, one cannot always use an app or voice to activate the light. Also in my case, we have lots of decorative lights where the lighting is fluorescent tubes etc or LED, we are unable to change the lighting element. The schneider electric 1-gang ulti switch (zigbee) is the best product that I have to be completely reliable and doesn’t require a neutral. ---

It is nice that you found a wall switch fit your case,in my case, using the Philips bulbs which require me to set the switch turning on all the time but I still can turn on or off the bulbs using the switches and they connect to the bridge instantly after turning on. Also, you can use Aeotec nano or micro switch or dimmer which function as a wall switch and you dont have to change the original wall switches of you house because replacing those switches may affect your house interior design.
