RTL_433

[qqlapraline]

Hello everyone,

I have tried using RTL_433 with a popular (and cheap ) OEM weather station: Sainlogic FT0300.
RTL_433 is retrieving all the necessary sensors data (Temp, Humidity, Wind speed and direction, rain, UV and Light) with the latest version of the tool.
Unfortunately, Domoticz is not able to retrieve the UV value.
It seems that the code is not consistent.

Here is how RTL_433 is sending back information in

Code: Select all

cotech_36_7959.c

Code: Select all

    data = data_make(
            "model",            "",                 DATA_STRING, "Cotech-367959",
            //"subtype",          "Type code",        DATA_INT, subtype,
            "id",               "ID",               DATA_INT,    id,
            "battery_ok",       "Battery",          DATA_INT,    !batt_low,
            "temperature_F",    "Temperature",      DATA_FORMAT, "%.1f F", DATA_DOUBLE, temp_c,
            "humidity",         "Humidity",         DATA_FORMAT, "%u %%", DATA_INT, humidity,
            "rain_mm",          "Rain",             DATA_FORMAT, "%.1f mm", DATA_DOUBLE, rain * 0.1f,
            "wind_dir_deg",     "Wind direction",   DATA_INT,    wind_dir,
            "wind_avg_m_s",     "Wind",             DATA_FORMAT, "%.1f m/s", DATA_DOUBLE, wind * 0.1f,
            "wind_max_m_s",     "Gust",             DATA_FORMAT, "%.1f m/s", DATA_DOUBLE, gust * 0.1f,
            "light_lux",        "Light Intensity",  DATA_COND, light_is_valid, DATA_FORMAT, "%u lux", DATA_INT, light_lux,
            "uvi",              "UV Index",         DATA_COND, light_is_valid, DATA_FORMAT, "%.1f", DATA_DOUBLE, uvi * 0.1f,
            "mic",              "Integrity",        DATA_STRING, "CRC",
            NULL);

And here is how Domoticz is parsing it in

Code: Select all

Rtl433.cpp

Code: Select all

	if (FindField(data, "uv"))
	{
		uvi = (float)atof(data["uv"].c_str());
		haveUV = true;
	}

Obviously, when it refers to UV Index, these two guys are not talking the same language
On my side, I have fixed it by adjusting the rtl_433 source on my device (I know, it's bad ). But the best way is probably to adjust it on Domoticz side.

Have a good day,

The best way is that you create a Pull Request on the Domoticz source code repository so everyone can enjoy the UV index value...

I'm using UV index for a while, but sending only integer value from 0 to 9 (or 10, I don't remind highest value)

Reported as issue https://github.com/domoticz/domoticz/issues/6534 and has been fixed.
