QPIGS CRC NOK on AXPERT VM IV Twin 4KVA

[ZdzislawC]

Hello, I can not read QPIGS data from my Voltronic Axpert VM IV Twin 4KVA Inverter. Other parameters are read correctly. Here is example of logs:

[16:35:26][D][pipsolar:837]: Sending polling command : QPIGS with length 5

[16:35:27][D][pipsolar:773]: checking crc on incoming message [16:35:27][D][pipsolar:782]: CRC NOK expected: DA 8A but got: 0 E7 [16:35:27][VV][scheduler:225]: Running interval 'update' with interval=1000 last_execution=100553597 (now=100554597)

There was no problem with QPIGS on my old 'burned' EAsun inverter :-(

I tried to add lines:

external_components:

• source: github://syssi/esphome-pipsolar@2424mse1 refresh: 0s

but compiler errors occur. Please help.

Hello. I have same issue with my invertes. After investigation I find the issue. The inverter protocol differs from expected. My Inverter protocol is descriebed in PI30_HS_MS_MSX_RS232_Protocol_20140822_after_current_upgrade.pdf (last reference in readme.md) QPIRI Inverter output: (230.0 23.9 230.0 50.0 23.9 5500 5500 48.0 49.0 48.0 57.9 57.9 2 02 060 1 2 3 1 01 0 0 00.0 0 1\x9EQ\r" Expected: (BBB.B CC.C DDD.D EE.E FF.F HHHH IIII JJ.J KK.K JJ.J KK.K LL.L O PP Q0 O P Q R SS T U VV.V W X current upgraded (BBB.B CC.C DDD.D EE.E FF.F HHHH IIII JJ.J KK.K JJ.J KK.K LL.L O PP QQ0 O P Q R SS T U VV.V W X Same for QPIGS Is there possible to configure version of used communication protocol?

I do not know why, but it start working for me, I reinstalled ESP32 device and it starts work.

Hi raivinigul, thanks for your information, it was an inspiration for me. I have changed the code to pip8048 and now everything is OK.
