Error description

A look in the source states that there should be "Hoymiles"

{

"unit_of_meas": "kWh",
"uniq_id": "112171909775_ch0_YieldTotal",
"dev": {

Same here, firmware version 0.5.78, on wmos D1 mini pro

Well I think the allocated size of the jsondocument is too small for the data. So the json isn't big enough and some values are dropped.

After shortening some data, like the inverter-name I get Homilies.

[sker65]

Well an example discover msg looks like:

{
  "name": "balkonoben CH1 U_DC",
  "stat_t": "inverter/balkonoben/ch1/U_DC",
  "unit_of_meas": "V",
  "uniq_id": "114183080207_ch1_U_DC",
  "dev": {
    "name": "balkonoben",
    "ids": "012345678912",
    "cu": "http://192.168.178.241",
    "mf": "Hoymiles"
  },
  "exp_aft": 65,
  "dev_cla": "voltage",
  "stat_cla": "measurement"
}

So the dev object has 105 byte, the whole msg is 336 byte in my example. Really too big? What about using the String class from the arduino runtime / stdlib and allocate strings more dynamically?

[lubeda]

In Zeile 149 von pubMqtt.h ist die Größe auf 128 begrenzt
149: DynamicJsonDocument deviceDoc(128);

Ich kann das aber nicht compilieren und testen. In dem Beispiel von sker65 fehlt z.B. auch der Wert mdl, der im Quelltext in Zeile 154 hinzugefügt wird.

See PR #630 for the current work in progress for #565 in the development03 branch.

I think it was already solved with the most recent development versions, please verify that.

[sker65]

I've tried the 0.5.81 and it does resolve the issue with mf set to null

[andreas-bulling]

same for me
