It is US wifi not Uk
Works well once reset to Europe wifi but it would not connect with their European/UK hub without a fair amount of resetting and liaison with tech support.I was expecting this so was not a problem for me.

Does not work in UK, description not clear
The hub and temperature sensors work well and are connected immediately. I purchased the 3-pack water leak sensors but did not realise the difference between UC and EC on the labels. UC does not work in the UK; you need to buy EC. I contacted tech support, but after an initial hello, I have been ghosted!
