closed: sent data via MQTTPush results in integer vaue iso float

Post by BartSr »

Hi!
I am using sent data via mqtt to HA
THe value e.g. gas meter shows in Domoticz 1165.118 but in mqtt exporer I only see 1165.
Is there a way to sent 1165.118 via MQTT or must I create a dummy device which shows gasvalue*1000?

I do not use MQTT so limited knowledge here.
What do you see when you ask the data through json API eg

Code: Select all

/json.htm?type=command&param=getdevices&rid=IDX
I see the float value as data so I would expect that MQTT would send that too

Code: Select all

"app_version" : "2024.7",
	"result" : 
	[

			"AddjMulti2" : 1.0,

Device in Domoticz says:

this is returned after comand : http://192.168.2.100:8080/json.htm?type ... es&rid=762

and this is what MQTT explorere says.

Code: Select all

domoticz
out = { "Battery" : 255, "LastUpdate" : "2024-10-16 22:45:30", "RSSI" : 12, "description" : "", "dtype" : "P1 Smart Meter", "hwid" : "10", "id" : "0001", "idx" : 762, "name" : "Gas", "nvalue" : 0, "org_hwid" : "10", "stype" : "Gas", "svalue1" : "1165130", "unit" : 2 }
As you can see it's an integer what's listed. So I presume this must be devided by 1000 to get correct value (m3)

So the question and conclusion (Domoticz is sending only the integer part) you started with is incorrect. You get the whole value in integer but in a different Unit of measure (Wh instead of kWh)
Then indeed you have to divide it with the same divider as set in your counter settings (in your case 1000)

Walter, I updated the post as I forgot to show the result of this value as sent by Domoticz. It seems you missed that (my bad).

This is what you wrote Which seems incorrect as in mqtt explorer you would have seen value 1165118 as you described later.

Walter, 1165118 was received from Gridcounter. That value goes in Domoticz. When I send that value via Domoticz (settings>more options>send data>Mqtt) it sends 1165.

Post by waltervl »

here you say something different. So you have to be clear:

Code: Select all

domoticz
out = { "Battery" : 255, "LastUpdate" : "2024-10-16 22:45:30", "RSSI" : 12, "description" : "", "dtype" : "P1 Smart Meter", "hwid" : "10", "id" : "0001", "idx" : 762, "name" : "Gas", "nvalue" : 0, "org_hwid" : "10", "stype" : "Gas", "svalue1" : "1165130", "unit" : 2 }

Walter, don't know what happened after I thought to have updated one of my posts it wasnot. Maybe forgot to submit again.
Having said this pls note: that when I send that value via Domoticz (settings>more options>send data>Mqtt) it sends 1165.
Can't copy a screenshot because the value is only visible in MQTT explorer once a value has changed. This did not happen for a few days as I didnot use gas.
Whereas I expect that hereunder is the result of P1 connection
domoticz
out = { "Battery" : 255, "LastUpdate" : "2024-10-16 22:45:30", "RSSI" : 12, "description" : "", "dtype" : "P1 Smart Meter", "hwid" : "10", "id" : "0001", "idx" : 762, "name" : "Gas", "nvalue" : 0, "org_hwid" : "10", "stype" : "Gas", "svalue1" : "1165130", "unit" : 2 }
So value sent out by Domoticz don't mention the decimal part.

@waltervl

Walter I was able to catch both the value from P1 meter (hardware ID 10 as well as the value sent by Domoticz. You can see that the decimal part is left. Is this how it should be?

Domoticz/out is the normal standard MQTT out topic. I don't know how you created the DomoHome/762 topic.

@Waltervl

Maybe there are more possibilities to get what you want but than still the question remains why MQTT sent via domoticz no complete value.
You asked how I got the DomoHome/762 topic.
See downbelow the screeshots.

OK, then I would submit a ticket at the Github repository that when using the MQTTPush function, data values are sent differently than the normal MQTT Hardware gateway. And show the difference as shown in your previous post.

As a workaround you could use the Domoticz/out message to send the data to HA.
