MQTT: sensor data not completly send out

[Toto1308]

Hi @ALL,

I use a smart meter with Tasmota and Mosquitto. First I will give all relevant data:

Tasmota version: 14.4.1
Stromzähler_Skript_Tasmota.txt

In Mosquitto following is shown for the actual config.
Sensor={"Time":"2024-12-18T21:25:19","SM":{"76_7_0":3786.81}}

Normaly I would expect something like this:
sensors={"sn":{"Time":"2024-12-18T21:06:30","SM":{"1_8_0":5984848.69,"1_8_1":1001.00,"1_8_2":5983847.00,"2_8_0":2221.00,"16_7_0":11660.91,"36_7_0":4060.41,"56_7_0":3805.35,"76_7_0":3795.15,"32_7_0":233.0,"52_7_0":233.1,"72_7_0":235.1,"96_1_0":""}},"ver":1}

So, the question now is, why are not all data send out? On the very first setup it worked. Then I tried some things with topic, full topic, device name, etc.. Since then the values are not transmitted.

What I have already done to solve the problem:

1. Reset the device
2. Reflash the device
3. Leave everything as given, except MQTT user, password and MQTT IP

Nothing seems to solve the problem. Any ideas?

If you need more informations, please give me a hint. Thank you.

Your help is really appreciated. Thank you very much in advance.

Best regards,
Thorsten

I think that the tasmota discovery message is sent before the script has been able to establish the sensor structure
This doesn't happens with native drivers but would happen with sensors/energy created from Scripting
I bet the same would happen with sensors & energy from Berry

May be @gemu2015 has some idea as I pretty sure I have a discussion about that in the past

[Toto1308]

Thank you for the first assessment. I hope, there is a solution for it.

[gemu2015]

check your tele period since the tele period cmd in the script is wrong i assume it is set to 5 minutes as default.

simply change
TelePeriod 30
to
=>teleperiod 30

in your script

[Toto1308]

I have changed it to teleperiod 30 in my script with a restart of the device. No change...

[gemu2015]

check in console
teleperiod

did you type =>teleperiod 30 in the script ?
"=>" is important

[Toto1308]

yes, I changed it without success.

Goal is to send every time all values. Do i need the teleperiod?

[Toto1308]

In the console it states 30s for teleperiod

[gemu2015]

check what is printed in the console. values should show up every 30 seconds.
also check what is shown after a restart in the console
may be sml is not initialized properly

[Toto1308]

yes, in the console I can see every 30 seconds all values, but inbetween only one or two values are transmitted to the mqtt server.

[Toto1308]

So actually when something changes on the value side, Tasmota sends out one or two values and after 30 seconds all values. Seems to be wrong

[gemu2015]

that is not supported directly in sml driver (only with extra scripting) !

set tele period to 10 and you will get all values at once every 10 seconds.

[Toto1308]

ok, now it works, I have changed all values from 18 back to 2 and the other ones -16. Thank you very much for your help.

[Toto1308]

One question: All values on the device HP are updated every 3 seconds. I estimate this is the rate my smartmeter sends out data. It would be great to send this directly to mqtt --> so how should the extra code look like?

[gemu2015]

first set "SM" in your meter descriptor to "*" which disables MQTT for this meter

then export every line to MQTT yourself every 3 seconds

like in this example:

>S
if upsecs%3==0 {
	=>Publish tele/%topic%/SENSOR {"SM":{"Energie Bezug":%2sml[1]%}}
}

%2sml[1]% is the value of sml decoder line 1 with 2 decimal places

add all the other values to the publish cmd above

[Toto1308]

Thank you very much for your help.
