I have also backed it and was on to him as well. I won’t post it all here, they are going to use a ASC712 to measure the current.
I was initially enquiring over the 10amp relay in the prototype and meeting BS1368. They were designing it to handle a max of 2200w for the China market, but I pointed out the need to handle 13A/3kw for the UK and in reality 15A for the US/EU market. He is not technical and I think some of it gets lost in translation with their tech guy. I pointed out that most humble electric kettles are now 3kw he came back that they would look at changing the design for the UK to handle it.
BTW. My understanding it the power monitoring/historical data etc will run through their own server, if so, it will interesting to see how long that will last. The switching will be controlled directly by the app, so no problems there...
I hope they do their research on testing and meeting the relevant standards, as they plan on distributing them from the UK. From my understanding makes them 100% liable for the item. It will be illegal to distribute them from the UK/EU without at least a CE mark (and probably a Kitemark) and it is hard to argue that CE means China Export when you are from the UK...
