Very cheap hardware let down by flaky software.
For the price this is a great product. I use two of these, controlling hot water and heating, and they give better control than standard methods.
The software is improving steadily but it has a number of issues that let down the excellent hardware; In the UK we have GMT & BST, otherwise known as Daylight Savings. Twice a year I have to reset all the time settings - a major pain in the neck! And all because China, the source of the software, doesn't change their clocks. A recent major re-vamp of the software has led to control buttons not working as they used to. Again a real nuisance.
In the early days the reliability of the connection to their servers was poor - this is now much better, and more improvements are promised.
