Questions regarding Button and Rain Sensor

[franki29]

Hi there,

what a great software, thanks for providing it.

I have two questions:

1.) Possible to have less Buttons (Like 6 ) but bigger ones?

2.) Is it possible to add Rain Sensor? Here a Json extract: Protected false Rain "1.2" RainRate "2223.6" ShowNotifications true SignalLevel "-" SubType "TFA" Timers "false" Type "Rain" TypeImg "rain" Unit 1 Used 1 XOffset

The problem is all users want a different homepage ^^. The next change will be more than 1 homepage. The code is dynamic, have you tried to set

    -DTOTAL_ICONX=3 # How many icon widht
    -DTOTAL_ICONY=2 # How many icon Heigh

for exemple ?

I m adding the rain sensor (a global "meteo" sensor in fact), but what is the "data" value on the json, I m using this one for all others sensors, strange this one use "RainRate "

And take care the actual version have memory issues (not stable), I m on it ATM

Edit: Have on mine

Data| "4920;0.0"

[franki29]

Hi, thanks for your answer. Icon is understood. And it is working at my side. After update to newest version Rain is now displayed but unfortunately the Rain rate, which is the total count. I would like to have the current on which will be Rain. (In my example 1.2) Where can i change it in the code?

[Smanar]

Where can i change it in the code?

Don't worry I can edit it, it will be fast. My problem is to find the value. I have created a "fake" sensor and all values are in "data" on my side (even they are too in "Rain" and "RainRate". It's not same for you ? If I m right as value you need to have x;y with x is the "Rainrate" and y the "rain" ?

[franki29]

No Rain and Rainrate is different. I need just the Rain value. As I do not have program skills I asked a well known AI (I know shame on me) but the result was : (And it seems to work) HttpInitDevice function: else if (strcmp(type, "Rain") == 0) { d->type = TYPE_METEO;

const char* rainData = i["Rain"];
if (rainData)
{
    if (d->data) free(d->data);
    d->data = (char*)malloc(strlen(rainData) + 1 + 1); // +1 for null char
    strncpy(d->data, rainData, strlen(rainData) + 1);
}

} And for Update:

// Update rain data if device type is "Rain" if (myDevices[ID].type == TYPE_METEO && RJson2.containsKey("Rain")) { const char* rainData = RJson2["Rain"];

    // Update rain data only if it's different
    if (strcmp(rainData, myDevices[ID].data) != 0)
    {
        // Allocate memory for new rain data if needed
        if (strlen(rainData) > myDevices[ID].lenData)
        {
            if (myDevices[ID].data) free(myDevices[ID].data);
            myDevices[ID].data = (char*)malloc(strlen(rainData) + 1);
            myDevices[ID].lenData = strlen(rainData);
        }

        // Copy rain data
        strcpy(myDevices[ID].data, rainData);
        NeedUpdate = true;
    }
}

And for Chart i did :

if (type == TYPE_METEO) v = i["mm"];

[franki29]

But I am pretty sure that this is not the right way to do

[franki29]

Also In my case the temperature should not be v *10 for the chart

[franki29]

For Rain, Temperature , Humidity , Pressure and Wind I have a Bresser Weather Station. The data are pushed by the https://github.com/matthias-bs/BresserWeatherSensorReceiver

[Smanar]

Thx, I will take a look tommorow But what is the "data" value ? It's not possible to use it ? (Because at least 99.99% of domoticz widget just use this field)

"Rain" is not present in "data" ? ("Rainrate" is)

[franki29]

Hi, no both are present:

Rain "1.2" (Current day rain data) RainRate "2223.6" (Total since device is on)

[Smanar]

But can you share your "data" field, this one is missing on your extract, and it's the more important for me

Protected false
Rain "1.2"
RainRate "2223.6"
ShowNotifications true
SignalLevel "-"
SubType "TFA"
Timers "false"
Type "Rain"
TypeImg "rain"
Unit 1
Used 1
XOffset

I have tried to make a fake rain sensor, but I have not the same than you, mine have all value in "data" (and in "Rain" and "Rainrate" too), so in my situation this one is enought.

You have value in "1" and "2" ?* 1 is the rainRate, 2 is the "rain" ?

[franki29]

Hi, it looks like this and here is the json: { "ActTime" : 1708880237, "AstrTwilightEnd" : "19:56", "AstrTwilightStart" : "05:37", "CivTwilightEnd" : "18:39", "CivTwilightStart" : "06:54", "DayLength" : "10:38", "NautTwilightEnd" : "19:18", "NautTwilightStart" : "06:15", "ServerTime" : "2024-02-25 17:57:17", "SunAtSouth" : "12:47", "Sunrise" : "07:28", "Sunset" : "18:05", "app_version" : "2024.4", "result" : [ { "AddjMulti" : 1.0, "AddjMulti2" : 1.0, "AddjValue" : 0.0, "AddjValue2" : 0.0, "BatteryLevel" : 255, "CustomImage" : 0, "Data" : "223920.0;2239.2", "Description" : "", "Favorite" : 1, "HardwareDisabled" : false, "HardwareID" : 3, "HardwareName" : "Wohnzimmer Lampe", "HardwareType" : "Dummy (Does nothing, use for virtual switches only)", "HardwareTypeVal" : 15, "HaveTimeout" : false, "ID" : "143BE", "LastUpdate" : "2024-02-25 17:57:11", "Name" : "Regen", "Notifications" : "false", "PlanID" : "0", "PlanIDs" : [ 0 ], "Protected" : false, "Rain" : "0.8", "RainRate" : "2239.2", "ShowNotifications" : true, "SignalLevel" : "-", "SubType" : "TFA", "Timers" : "false", "Type" : "Rain", "TypeImg" : "rain", "Unit" : 1, "Used" : 1, "XOffset" : "0", "YOffset" : "0", "idx" : "878" } ], "status" : "OK", "title" : "Devices" }

[franki29]

The device only send the total amount of rain as far I know, the rest must be calculated

[Smanar]

"Data" : "223920.0;2239.2", "Rain" : "0.8", "RainRate" : "2239.2",

The device only send the total amount of rain as far I know, the rest must be calculated

Yes I m seing.

/json.htm?type=command&param=udevice&idx=IDX&nvalue=0&svalue=RAINRATE;RAINCOUNTER

    IDX = id of your device (This number can be found in the devices tab in the column "IDX")
    RAINRATE = amount of rain in last hour in [mm x 100]
    RAINCOUNTER = continues counter of fallen Rain in [mm]

So data contain only Rainrate and total counter, and you need the "today rain" ? So no choice, need to make like you have done. I will try to update the code tommorow.

[Smanar]

Ok, so have corrected a big issue, with the help from the arduinojson lib dev. Have added a "hack" for this sensor, the data will now contain 3 fields, the total rain, the rain rate and the today rain.

If you want to test it, the code is atm on the "test" branch, so much critic code to be pushed on master immedialty.

[Smanar]

Have corrected something yesterday, graph was not working, but still on "test" branch.

[franki29]

Hi I tested the newest version where you insert the special device for Rain. Output is now : 224280.0 2242.8 0.0

But I need only the 0.0. (Sunny Day :-) )

So I add:

if (RJson2.containsKey("Rain")) { data = Cleandata(JSondata, RJson2["Rain"]);

// Assuming data is a char* representing the cleaned data

// Find the position of the second newline character
char *startIndex = strchr(data, '\n');
if (startIndex != NULL)
{
    startIndex = strchr(startIndex + 1, '\n');
    if (startIndex != NULL)
    {
        // Extract the substring after the second newline
        startIndex++; // Move startIndex to the character after the second newline
        Serial.println(startIndex);
        data=startIndex;
    }
}

}

and if (i.containsKey("Rain")) { data = Cleandata(JSondata, i["Rain"]); // Assuming data is a char* representing the cleaned data

// Find the position of the second newline character
char *startIndex = strchr(data, '\n');
if (startIndex != NULL)
{
    startIndex = strchr(startIndex + 1, '\n');
    if (startIndex != NULL)
    {
        // Extract the substring after the second newline
        startIndex++; // Move startIndex to the character after the second newline
        Serial.println(startIndex);
        data = startIndex;
    }
}

}

To get only the third entry, but again with help from the AI

[Smanar]

But the problem is another user might want another field, it's not good if you have all of them ?

[franki29]

In case of the bresser sensor I think it make no big sense as you do not know at what date the sensor was starting for collection of rain data. The calculation of rain per hour is made by Domoticz.

Of course with other rain sensor it might be good to have it.

Ha yes, not wrong, a counter is stupid for that except if you reset it manualy at some period ..... Honnestly IDK what to do, lol. And I think ALL rain sensor works same, I have created one, and it works like yours. As you are the first one that is trying this sensor, there is something easier to code, replace

    if (RJson2.containsKey("Rain"))
    {
        data = Cleandata(JSondata, RJson2["Rain"]);
    }

by

    if (RJson2.containsKey("Rain"))
    {
        data = Cleandata(RJson2["Rain"]);
    }

You will have only 1 value, but the good one. Need to do same for

        if (i.containsKey("Rain"))
        {
           data = Cleandata(JSondata, i["Rain"]);
        }

The last code version is on branch "test", I have just updated it, so this change will be in next version.

[franki29]

Hi, in the main release the graph for rain does not work anymore. Here are the data: (Graph chows only 0 for all data))

  |   -- | -- result |   0 |   d | "2024-03-28 16:00" mm | "0.0" 1 |   d | "2024-03-28 17:00" mm | "0.0" 2 |   d | "2024-03-28 18:00" mm | "0.0" 3 |   d | "2024-03-28 19:00" mm | "0.0" 4 |   d | "2024-03-28 20:00" mm | "0.0" 5 |   d | "2024-03-28 21:00" mm | "0.0" 6 |   d | "2024-03-28 22:00" mm | "0.0" 7 |   d | "2024-03-28 23:00" mm | "0.0" 8 |   d | "2024-03-29 00:00" mm | "0.0" 9 |   d | "2024-03-29 01:00" mm | "0.0" 10 |   d | "2024-03-29 02:00" mm | "0.0" 11 |   d | "2024-03-29 03:00" mm | "0.0" 12 |   d | "2024-03-29 04:00" mm | "0.0" 13 |   d | "2024-03-29 05:00" mm | "0.8" 14 |   d | "2024-03-29 06:00" mm | "0.4" 15 |   d | "2024-03-29 07:00" mm | "0.0" 16 |   d | "2024-03-29 08:00" mm | "0.0" 17 |   d | "2024-03-29 09:00" mm | "0.0" status | "OK" title | "Graph rain day"

[Smanar]

I think it's because values are too low, all < 1 and decimal. Have updated the code on the "test" branch.

[franki29]

Great works, thank you very much
