Hi.
I am using arduinojson library in esphome, in the latest versions they have switched from version 5 to 6 and my conde cannot compile anymore. According to upgrade tutorial i have do some changes and test test but i cant get it working 
i am not expert of c++ this migration is hard for me.
Can you help me please?
This is the code previously working on arduinojson5:
//Forecast
if (id(forecast_5).has_state())
{
int wxx;
int wyy;
int forday = 1;
const size_t capacity = JSON_ARRAY_SIZE(5) + 5*JSON_OBJECT_SIZE(5) + 560;
DynamicJsonBuffer jsonBuffer(capacity);
JsonArray& root = jsonBuffer.parseArray(id(forecast_5).state.c_str());
//for (int i=0; i<root.size(); i++)
for (int i=0; i <= 3; ++i)
{
if (i == 0) {wxx = wx;}
if (i == 0) {wyy = wy;}
if (i == 0) {forday = (id(esptime).now().day_of_week +1);}
if (forday == 8)
{
forday = 1;
}
//Day 3-4 go down
//if (i == 2) {wyy += 38;}
//if (i == 2) {wxx = 0;}
JsonObject& root_0 = root[i];
std::string root_0_condition = root_0["condition"]; // "sunny"
float root_0_precipitation = root_0["precipitation"]; // 0.8
float root_0_temperature = root_0["temperature"]; // 20.2
float root_0_templow = root_0["templow"]; // 11.3
//std::string root_0_datetime = root_0["datetime"]; // "2021-10-22T10:00:00+00:00"
//int root_0_wind_bearing = root_0["wind_bearing"]; // 212
//float root_0_wind_speed = root_0["wind_speed"]; // 9.4
//Print to screen
//Translated day
it.printf(wxx, wyy, id(font_small), id(my_green), TextAlign::TOP_CENTER, "%s", dayDict_ext[forday]);
//Icon condition
it.printf(wxx, wyy +12, id(weather_font), TextAlign::TOP_CENTER, "%s", fonDict[root_0_condition.c_str()]);
//Temp max
it.printf(wxx, wyy+60, id(font_small_1), TextAlign::TOP_CENTER, "max %.0f°", root_0_temperature);
//Temp min
it.printf(wxx, wyy+70, id(font_small_1), TextAlign::TOP_CENTER, "min %.0f°", root_0_templow);
//Rain in mm
it.printf(wxx, wyy+80, id(font_small_1), TextAlign::TOP_CENTER, "%.0f mm", root_0_precipitation);
//lines
it.line(0, wy, it.get_width(), wy);
it.line(0, wy+95, it.get_width(), wy+95);
wxx += 85;
forday += 1;
}
}
It give me a series of webfont icon, and below temperature precipitation etc..
This is the test that i have done for migrating to 6:
//Forecast
if (id(forecast_5).has_state())
{
int wxx = 0;
int wyy = 0;
int forday = 1;
StaticJsonDocument<768> root;
deserializeJson(root, (id(forecast_5).state.c_str()));
//for (int i=0; i <= 3; ++i)
for (JsonObject item : root.as<JsonArray>())
{
if (item == 0) {wxx = wx;}
if (item == 0) {wyy = wy;}
if (item == 0) {forday = (id(esptime).now().day_of_week +1);}
if (forday == 8)
{
forday = 1;
}
//Day 3-4 go down
//if (i == 2) {wyy += 38;}
//if (i == 2) {wxx = 0;}
JsonObject root_0 = root[item];
std::string root_0_condition = root["condition"]; // "sunny"
float root_0_precipitation = root["precipitation"]; // 0.8
float root_0_temperature = root["temperature"]; // 20.2
float root_0_templow = root["templow"]; // 11.3
//std::string root_0_datetime = root["datetime"]; // "2021-10-22T10:00:00+00:00"
//int root_0_wind_bearing = root["wind_bearing"]; // 212
//float root_0_wind_speed = root["wind_speed"]; // 9.4
//Print to screen
//Translated day
//it.printf(wxx, wyy, id(font_small), id(my_green), TextAlign::TOP_CENTER, "%s", dayDict_ext[forday]);
//Icon condition
//it.printf(wxx, wyy +12, id(weather_font), TextAlign::TOP_CENTER, "%s", fonDict[root_0_condition.c_str()]);
//Temp max
it.printf(wxx, wyy+60, id(font_small_1), TextAlign::TOP_CENTER, "max %.0f°", root_0_temperature);
//Temp min
it.printf(wxx, wyy+70, id(font_small_1), TextAlign::TOP_CENTER, "min %.0f°", root_0_templow);
//Rain in mm
it.printf(wxx, wyy+80, id(font_small_1), TextAlign::TOP_CENTER, "%.0f mm", root_0_precipitation);
//lines
it.line(0, wy, it.get_width(), wy);
it.line(0, wy+95, it.get_width(), wy+95);
wxx += 85;
forday += 1;
}
}
Now all the values report "0" sure there is something wrong that i dont'understand. I am not sure this is the right way.
Thank you in advice
