Yup, £24 is the best I’ve obtained and would be like US ST prices after conversion. For normal sales, you could couple that with Quidco. UK is far too expensive for smartthings. Could do with done competition. Curry’s aren’t doing a great job promoting ST either. Been to 3 shops, sales guys know jack.
Surely that doesn’t surprise you? I wouldn’t call Curry’s particularly knowledgeable on anything they sell, let alone really techy stuff that’s for a very limited market. I made the comment in another thread a while back that Curry’s being the only retailer of ST in the UK doesn’t bode well for its future in the UK.
Curry’s Sales of ST = Limited UK users = limited demand of official support = limited official UK development
Everspring is usually the cheapest, but for a reason – – the engineering is a whole level less expensive than most other brands. But that may be acceptable for a door sensor. These typically retail for just under £30, so if you can find them on sale, they’re usually the least expensive.
Another brand to look for which is of a higher quality and surprisingly lower-priced than similar brands is DLink. The sensors are sold in the UK under the “myDlink” brand. Usually at about the same list price as the Everspring. Some places that carry the D-Link routers will also carry these. They’re certainly worth looking for. Just make sure you get the Z wave ones, not the Wi-Fi ones. (The Wi-Fi ones work fine, they just are not compatible with SmartThings.)
I often say this, but it’s worth repeating: personally, I only buy electronics from a place with a good returns policy. There are a lot of counterfeits and misboxed items sold on eBay and similar sources. So I would rather pay a little more and buy with more confidence. But obviously that’s a personal decision.
Peq sensors are zigbee, but they may be illegal for use in the UK because they use “boosted” zigbee which transmits at a level almost twice that of the allowed EU maximum. This is true of most zigbee devices manufactured for sale in the US. You just need to check each one to see if it is using output broadcast power above the level of 12 db.
Incidentally, I tried to Google the difference between the power levels permitted with US and EU ZigBee devices, but most of the relevant hits came from the community here, where it’s often stated as a fact.
Has anyone got a reliable external source for this information, and the ‘fact’ that US sensors are using a boosted version of ZigBee?
Most of the papers I found stated that the ZigBee standard doesn’t impose a maximum power level, but the EU does, and so most devices on the market use this as the design basis for their chipset+antenna. I also found many examples of tests showing devices transmitting BELOW this level in order to increase battery life.
I’m sure there must be a solid basis of the info that’s so often repeated here, though. It would just be interesting to know where it came from!
Again, any references or papers dated prior to 2014 will not show these limitations. The previous standards allowed for higher output. Consequently you can find many 2014 trade papers for manufacturers discussing how they intend to meet the new lower output standards in the EU.
edited to add that the newest generation of SmartThings-branded US sensors has moved a few more to the unamplified group. See the complete list in Tyler’s list below.
Thanks - interesting. But where do we get the information that manufacturers are adopting a US/EU split, and not just making all of their devices worldwide compliant? Especially the accusation that Samsung is producing different versions of their ‘things’ for the two markets ?
It’s not an accusation. It’s now standard industry practice, as can be seen from some of the links in the previous post. The power has to be dialed down if the device is to be sold in the EU.
Complying with the EU standard would mean that the devices have a shorter broadcast range than US laws would allow. That would put a “universal” model at a significant competitive disadvantage for the US market, as most consumers look for the longest range possible for most home automation devices . Hence the reason why most of these manufacturers make two versions if they want to sell in both markets.
There are many different standards that apply to devices sold in the two regions. Having a CE certification for the UK is not the same as having a UL listing or an FCC certification for the US. So it is not at all uncommon for electronics devices, networked or not, to be made in different models for the two markets.
At present, Samsung does not manufacture the sensors and pocket sockets sold under the SmartThings brand. They’re manufactured by other companies and then relabeled by SmartThings, as was done before the Samsung acquisition.
In the US, they are manufactured by Centralite. I haven’t looked into the exact sourcing for the UK versions, but there should be a compliance label on the back or inside the battery compartment which lists the licenses, and from there you can look up the manufacturer.
I asked this very question in another thread and a member of the smartthings support team confirmed that US and UK devices are all different with the exception of the arrival sensor which is exactly the same.
