Hi, I just finished flashing my 4 way wall touch switch. Everything works well. It can be controlled by web UI and also with home assistant flawlessly. But direct touch of wall switch works with latency and it's annoying. When you touch the switch its state will change after about 0.2sec to 0.5sec and you may think it's not working and you will touch it again and it will change the switch state again.
