Features that are clearly underdeveloped

In theory, the SONOFF S-MATE Switch connected to the MINIR3 supports three mechanical switches. Each of them can implement three scenes, depending on the user’s behaviour. This is not the case. A long press does not work and a double press is recognised as single. The control of the MINIR3 itself is flawless, while the control of other WiFi devices hardly works as intended or expected. Sometimes a change of state happens with a great delay (even several minutes). But mostly it is simply not working.
The R5, on the other hand, does not handle long presses correctly. If they work at all, they’re executed with errors, like on and immediately off.
I understand that eWeLink-Remote is new. This does not change the fact that you are currently promising features that are clearly severely underdeveloped.
