F16 tuya reverse sw. function missing

[admin]

if you want switch tun on/off relay. you should download KCS v3 firmware to your board. set by IFTTT, let digital input TOGGLE relay output. this is local way, it's fast speed. here is KCS v3 online guide: https://www.kincony.com/how-to-use-kcsv3...board.html
we don't suggest use tuya app set for wall switch, because it need internet cloud server, so it will have delay.
