Goodwe inverter HC3

[martin7462]

Hello,

I have a Goodwe EM3648-EM converter. I installed Homeassistance (HA) for data. I have HC3 fibaro and I would like to have some data in fibaro. HA communicates with the inverter via UDP and  reading data directly from the inverter every 5 seconds. I started testing the communication via shark and found that HA is sending a command to Goodwe - aa55c07f0106000245. 

 

I use some QA for UDP comunication in HC3 .

The result is that QA command:

string.char(0xaa,0x55,0xc0,0x7f,0x01,0x02,0x00,0x02,0x41)

string.char(0xaa,0x55,0xc0,0x7f,0x01,0x06,0x00,0x02,0x45)

send data to HC3 in same format but long data. ( attachment aa.odt) . Data have format tarting 5C75303030 and after is parameter I thing.

 

I'm not that good at programming anymore, but maybe it will help someone, in case it helps to do basic QA for getting data from the inverter, similar to homeassistance.

 

In attachment is QA which get data from inverter.

I have it . I have first experimental QA. If you somebody o want I will send you but I need help with by finding out where it is given individually in the packets found in the case of how to calculate them. I have SOC, PV1, PV2 and temperatures..

I did it. I have QA for local connection with HC3 and Goodwe series like in Homeassistance for ET, EM and DT series.. If you want QA contact me with message on forum https://forum.fibaro.com/topic/63203-goodwe-hc3/.
