Got them all previously. The hub, no never again. The water sensors are wonky, they sometimes freak out and send constant wet/dry messages. Had to RMA mine.
The other devices all work very well with HE.
I have 4 of the water sensors now for aprox. 6 months and they haven't given me any issue. One informed me of a flood in my basement when my Father in Law left the sprinklers on in the garden and flooded through a basement window. Doubling down tonight and picked up 9 on sale. Going to add them to my sinks, under the fridge's water line, dish washer and the washing machine.
Interestingly, it currently sells for CDN$69.99 in Canada (from Samsung's Canadian site). That's about US$52. One of those rare moments when a consumer product is cheaper north of the 45th parallel.
In comparison, Hubitat's US$69.99 converts to CDN$93 (~80% more expensive). Unless one is aware of Hubitat's advantages, the two products appear to be equivalent to the average consumer ... so the Canadian pocketbook seeks out Samsung's hub.
Food for thought: special Canadian pricing on Boxing Day.
