no data from Voltronic Axpert MKS IV

[byte4geek]

Hi,

i have the issue with Voltronic Axpert MKS IV.

in the serial on nodemcu i can see only

QPIGS▒▒

in mqtt only:

Client null received PUBLISH (d0, q0, r0, m0, 'solar/INVERTER1/uptime', ... (66 bytes))
solar/INVERTER1/uptime {"human":"0 days, 0 hours, 13 minutes, 38 seconds", "seconds":818}
Client null received PUBLISH (d0, q0, r0, m0, 'solar/INVERTER1/wifi', ... (44 bytes))
solar/INVERTER1/wifi { "FreeRam": 46872, "rssi": -43, "dbm": 100}

but no data of the inverter is present.

i tryed the project with raspberry (https://github.com/ned-kelly/docker-voltronic-homeassistant) and the usb cable and it works fine.

But your solution is better and cheaper.

someone can help me?

With another serial on tx a can see:
(225.4 50.0 225.4 50.0 0000 0000 000 308 00.80 000 000 0023 00.1 000.0 00.00 00000 00010000 00 00 00000 0106K ▒
but i think the buffer is too small and the data was cutted.

now i can see these data in the mqtt:

Client null received PUBLISH (d0, q0, r0, m0, 'solar/INVERTER1/uptime', ... (66 bytes))
solar/INVERTER1/uptime {"human":"0 days, 0 hours, 15 minutes, 42 seconds", "seconds":942}
Client null received PUBLISH (d0, q0, r0, m0, 'solar/INVERTER1/wifi', ... (43 bytes))

solar/INVERTER1/batta 225.90
Client null received PUBLISH (d0, q0, r0, m0, 'solar/INVERTER1/wattage', ... (4 bytes))
solar/INVERTER1/wattage 0.00
Client null received PUBLISH (d0, q0, r0, m0, 'solar/INVERTER1/solara', ... (5 bytes))
solar/INVERTER1/solara 50.00
Client null received PUBLISH (d0, q0, r0, m0, 'solar/INVERTER1/status', ... (63 bytes))
solar/INVERTER1/status {"battv":50,"solarv":225,"batta":225.9,"wattage":0,"solara":50}

battv report the frequency
solarv report the net volts
solara repot the frequency

I tryed all three model but it send only data with PCM but i think it is a PIP, how can i fix it?

[byte4geek]

Why with settings as PIP the software write ^P003GS2▒ ?
and if i set PCM it write QPIGS▒▒ but nothing is received from inverter.
with a another com port i write QPIGS 5 , the inverter respond with data.

can you help me?
