Can you add better support for washing machine RO41274DWMCE/1-S?

[ja79]

I complited:
"ip_address": "192.168.1.75",
"password": "[add key from Candy Simply-Fi tool by Melvin Groenendaal]",
"use_encryption": "1"
For now, I only have 3 entities, no controls.
Communication is coded.
After decoding I got:
{
"statusLavatrice":{
"WiFiStatus":"1",
"Err":"0",
"MachMd":"1",
"Pr":"1",
"PrPh":"0",
"PrCode":"136",
"SLevel":"0",
"Temp":"40",
"SpinSp":"12",
"Opt1":"0",
"Opt2":"0",
"Opt3":"0",
"Opt4":"0",
"Opt5":"0",
"Opt6":"0",
"Opt7":"0",
"Opt8":"0",
"Opt9":"0",
"Steam":"0",
"DryT":"0",
"DelVal":"0",
"RemTime":"2340",
"RecipeId":"0",
"Lang":"12",
"FillR":"0",
"DisTestOn":"0",
"DisTestRes":"0",
"CheckUpState":"0",
"T0W":"1",
"TIW":"0",
"T0R":"0",
"numF":"0",
"unbF":"0",
"unbC":"0",
"NtcW":"162",
"NtcD":"6",
"motS":"0",
"APSoff":"0",
"APSfreq":"62344",
"chartL":"156842"
}
}
I can also turn the washing machine on and off with codes:
http://xxx.xxx.xxx.xxx/http-write.json?encrypted=1&data=coded_zzz
zzz:
turn on: StSt=1
turn off: StSt=0

But I cannot change the washing program, temperature or spin speed.
