I have 4 KC868-E16P-V2.3 with firmware version 2.2.14, after about one week, they go offline, no TUYA access(TUYA show Offline), and there is no Web-access. I have to power off/on to make them come online. It's random witch controller who goes offline, but all of them goes offline during one week or so.
They are powered by a MeanWell 12V 2.5A DIN-rail powersupply.
