I use NodeRed with this function to get data to Domoticz

Code: Select all

var IDX = global.get('idxTable','memoryOnly')['Water'].idx;
var msg1 = {};
var msg2 = {};
if (msg.payload.error == 'no error') {
    msg1.payload = { "command": "udevice", "idx": IDX, "svalue": msg.payload.value.toString()};
    msg2.payload = { "command": "addlogmessage", "message": "Water value: "+msg.payload.value.toString()};
} else {
    msg1.payload = { "command": "addlogmessage", "message": "Water ERROR: "+msg.payload.error};
//    msg2.payload = { "command": "sendnotification", "subject": "WATER ERROR!", "subsystem": "pushover", "body": msg.payload.error, "priority": 0};
}
//return msg;
return [[msg1, msg2]];

and have this Device in Domoticz.

This works fine with a nice history.

I'm using Domoticz since 2008, but I don't know why, I only register to this forum today ... don't ask me why

The first release of Domoticz was in december 2012.

let msg1 = {};
let msg2 = {};

if (msg.payload.hasOwnProperty("error")) {
    msg = null;
    return msg;
} else {
    msg1.payload = { "command": "udevice", "idx": 532, "nvalue": 0, "svalue": ((msg.payload.total_liter_m3) * 1000).toString() };
    msg2.payload = { "command": "udevice", "idx": 533, "nvalue": 0, "svalue": (msg.payload.active_liter_lpm).toString() };
return [[msg1,msg2]];
}

msg.payload : Object
object
wifi_ssid: "Name "
wifi_strength: 100
total_liter_m3: 41.778
active_liter_lpm: 0
total_liter_offset_m3: 0

If I'm passing the value in litre, it looks like the divider in the Domoticz setup should state 1000000

Counter
/json.htm?type=command&param=udevice&idx=IDX&svalue=COUNTER
IDX = id of your device (this number can be found in the devices tab in the column "IDX")
COUNTER = Integer of the overall total counter (Energy, Volume, Custom).

When there is a counter created, there is a possibility to change the units by clicking on "Change" at the utility tab.

Energy (reports kWh), give COUNTER value in Wh, integer
Energy Generated (reports kWh). give COUNTER value in Wh, integer
Gas (reports m3) , give COUNTER value in liter (1000 liter = 1 m³), integer
Water (reports m3), give COUNTER value in liter (1000 liter = 1 m³), integer
Counter (no unit)
Time (min?), seems to be obsolete, use Counter instead and use the time units as desired (eg Sec, min, hrs)
The counter will be treated with the divider which is defined in the parameters in the application settings (menu setup-settings, tab counters). For example if the counter is set to "Water" and the value is passed as liters, the divider must set to 1000 (as the unit is m3). The device displays 2 values:
The status is the overall total volume (or counter).
The volume (or counter) of the day (in the top right corner).
The today's volume (or counter) is calculated from the total volume (or counter).

Best regards

In your first post you stated:

I suggest you to read the Wiki and then also this page: https://www.domoticz.com/wiki/About_Domoticz

In the first paragraph, last line, you will see:

The first release of Domoticz was in december 2012.

So beside that you obviously use hardware, before this has been produced, you have also access to software, before its release.
That is special and maybe you want to share the future with us

Well, after the joke, please find also my graphs.

Just FYI,

Like @kedi, I use Node-RED as well, for the Watermeter.

I use the following Function node, before I send it to Domoticz with MQTT.

Code: Select all

let msg1 = {};
let msg2 = {};

if (msg.payload.hasOwnProperty("error")) {
    msg = null;
    return msg;
} else {
    msg1.payload = { "command": "udevice", "idx": 532, "nvalue": 0, "svalue": ((msg.payload.total_liter_m3) * 1000).toString() };
    msg2.payload = { "command": "udevice", "idx": 533, "nvalue": 0, "svalue": (msg.payload.active_liter_lpm).toString() };
return [[msg1,msg2]];
}

Important is that you send the value in liter (so you have multiply the m3 x1000). And to correct that again setup your global divider for water with 1000)

The Question to @Kedi: can you confirm the Meter Offset is used to tell the sensor not to start from 0 but from the current meter value ?

Yes I can, but I saw recently something new.

If I send a http request to the watermeter, I receive the following:

Code: Select all

msg.payload : Object
object
wifi_ssid: "Name "
wifi_strength: 100
total_liter_m3: 41.778
active_liter_lpm: 0
total_liter_offset_m3: 0

Previously "total_liter_offset_m3" was not available. So obviously you can set also the offset in the Home Wizard app. In that case, I assume, you should not use the offset in Domoticz. However, I have not been able to find that setting, yet.

Best regards

Do not forget to change the IP address in the HTTP request node to your own needs and that the IDX numbers in line 8 and 9 in the Function node match with your virtual IDX's in Domoticz.
