[syssi]

Do you need help here? Is the second SMG on the same modbus (with different modbus addresses) or do you want to talk to the device using a second uart?

[amgstone]

I want to transfer from 3 esp to 1.

[syssi]

Are you able to change the modbus address of one of your inverters?

[syssi]

I've merged the three YAMLs into one. The modbuss address of the second inverter should be changed to 0x02. Please attach both inverter to the same modbus. It' possible the ESP32 cannot handle the large amount of entities. Please give it a try.

smg-smg-jk.yaml.txt

[amgstone]

doesn't work like that, you have to split into 2 rx and 2 tx

[syssi]

Please attach the second RS485 converter to GPIO32/GPIO33: smg-smg-jk-v2.yaml.txt

[amgstone]

works great, thank you very much!!!

[amgstone]

but for some reason often esp becomes unavailable

[syssi]

Please plug the ESP32 into a computer and record a log via a serial connection. You should see possible reboots or connection hiccup here.

In general: Doing BLE communication is a heavy task and doesn't harmonize with the WiFi connection. There are ESP32 boards available with an Ethernet module (WT32-ETH01). Avoiding WiFi would provide additional stability.

[amgstone]

Good day. You can make a configuration with two inverters, and then I will make bms on another esp.

[amgstone]

just once a day esp stops sending information from bms to HA, although smg continues to work. only reboot esp helps

[syssi]

smg-smg-v3.yaml.txt

[amgstone]

divided into 2 esp32, one on 2 doruga infertors for bms. Overloaded only where bms.
