Thanks for the answers.
My option no. 1 would be to buy on local (national) market. No problem with radio frequency, quick support, no shipping problems, taxes, customs etc.
… due to strange Samsung SmartThings sell strategy it seems for EU there is only UK as supported country.
And if I can then choose between US and UK, US is the winner for me because:
- 60 USD in US vs. 96USD in UK for hub
- 20 USD in US vs. 29USD in UK for Water leak or Multiputpose sensor (and I am sure all other are chaper in US)
- no shipping costs
So if I think about hub + 5 sensors, with US products I will save 81 USD (plus shipping as I can have it from US without any shipping fee (friend)). So I am sure at least 100USD saved. With more sensors of course savings are higher. Plus I assume if I need ZigBee device to connect it necessairly does not need to be from US (because of 2,4 GHz standard)
This is my most motivation to think about US one, instead of UK. I know there is also topic about frequency and if it is legal in country but let´s do not think about this, I am now more focused on technical part and if it is working. Or should. Also if there is no “geo blocker” so it is not problem to connect US hub in Europe, no Samsung SW related restrictions or so.
