Backlog TuyaMCU 33,20; TuyaMCU 32,18; TuyaMCU 31,19; SetOption66 1; SetOption19 1; SetOption53 1;

TuyaMCU 33,20 -> Voltage doesnt shows correctly in tasmota (usually shows thousands of volts, it’s not calibration related problem, I guess its a resolution problem), so I used Home Assistant instead.

RESULT = {"TuyaReceived":{"Data":"55AA030700081402000400037922C9","Cmnd":7,"CmndData":"1402000400037922","DpType2Id20":227618,"20":{"DpId":20,"DpIdType":2,"DpIdData":"00037922"}}}

37922C9 -> 37922 -> hex a dec -> 227618 -> 227,618vac (tasmota shows 22761 V)
