Metern: indicator value empty

[novembre62]

HI I have an energy meter that measures today's energy which is reported in the indicators When the meter value is "0", the indicator value is "Empty" It is possible to display "0"

Use with Metern 1.2.4.1 Raspberry PI5 with bookworm

Thank you

Hi, What output exactly your command ?
your 0 should not be quoted

[novembre62]

in reqsdm.php ...... } elseif ($argv[1] == 'pow3oggi') { $url = 'http://192.168.1.42/cm?cmnd=Status%2010'; $pagina = file_get_contents($url); $json_output = json_decode($pagina, true); $val = $json_output['StatusSNS']['ENERGY']['Today']; $outstr = ("10($val*w)\n"); ....... http://192.168.1.42/cm?cmnd=Status%2010 returns {"StatusSNS":{"Time":"2024-03-08T08:39:42","ENERGY":{"TotalStartTime":"2023-03-17T00:00:00","Total":1367.148,"Yesterday":0.000,"Today":0.000,"Power":0,"ApparentPower":0,"ReactivePower":0,"Factor":0.00,"Voltage":230,"Current":0.000}}}

"Today":0.000

Therefore in metern indicators Command = reqsdm pow3oggi

the value is "empty" only when the Today value is 0, while it is displayed correctly when the value is greater than 0

this also happens with other indicators

[jeanmarc77]

What returns reqsdm pow3oggi from CLI ? Maybe change reqsdm with $outstr = utf8_decode($outstr); echo "$outstr";

[novembre62]

returns reqsdm pow3oggi from CLI:

10(0*w)

[jeanmarc77]

and what returns metern/programs/programindicator.php ?

[novembre62]

returns metern/programs/programindicator.php :

{"Tensione1":"234.15","Temp CPU2":"53.45","Distacco lavanderia3":"OFF<\/font>","Distacco clima4":"OFF<\/font>","Acqua giorno5":"105","Clima nuovi oggi6":"empty"}

and this : Clima nuovi oggi6":"empty"

[novembre62]

I think this happened with the new version of metern...but I'm not sure

[jeanmarc77]

i don't have such issue.. What show "more /dev/shm/mN_ILIVEMEMORY.json" ?

[novembre62]

/dev/shm/mN_ILIVEMEMORY.json :

{"Tensione1":"238.09","Temp CPU2":"52.9","Distacco lavanderia3":"OFF<\/font>","Distacco clima4":"OFF<\/font>","Acqua giorno5":"133","Clima nuovi oggi6":"empty"}

Try using latest https://github.com/jeanmarc77/meterN/blob/main/scripts/metern.php and restart

[novembre62]

should I replace my metern.php with the one indicated in the link?

[jeanmarc77]

yup

[novembre62]

done...but nothing changes

[novembre62]

...I add that by replacing metern.php, even some meters, which at this moment have a value of 0, "empty" is displayed

[jeanmarc77]

dunno, it work here but it's been a while.. i somehow remember i have changed that behavior.. Maybe change also https://github.com/jeanmarc77/meterN/blob/main/index.php

[novembre62]

replaced index.php, but no change

however, the system works well....the values are correctly displayed and counted when they are different from 0 It was just to not see "empty" when the value is 0 Thank you very much for your availability

[jeanmarc77]

[jeanmarc@zbox ~]$ houseenergy -frq 1_F(0*Hz)

programindicator.php returns {"Volt1":"230.7","Freq2":"0","Cos3":"0.7","Main4":"14920","peak5":"4851.5","low6":"6"}

and my index show 0

Sorry i don't code much theses days

[novembre62]

Thanks again

[novembre62]

Good morning I solved it like this:

added to metern.php after line 314

if ($val === 'empty') { // Check if the value is 'empty' $val = 0; // Set the value to 0 if it is 'empty' }

Now when the value of an indicator is 0, 0 is displayed

[jeanmarc77]

Well, if you it mean your com app return 'empty' in cli
