Huawei Integration for HA at the same time as Modbus Integration for HA

[richardpub4136]

Can I use Huawei Integration for HA at the same time as Modbus Integration for HA, without going through a Modbus Proxy?

Why did you need a modbus proxy? You can use that integration independently from the native modbus HA integration. I suppose huawei_solar has an internal and independent modbus management so you don't need to configure a specific modbus connection for huawei_solar.

I use the Huawei solar integration but I am trying to connect to modbus with Node-red but the connection does not connect to my Huawei inverter for which I want to discover the different parameters in real time. I wonder if the number of simultaneous has a limit ???
thanks for tour response

Yes you need the modbus proxy if you want to connect multiple systems to the same inverter. Both the HA integration and Node Red have to connect to the proxy.

Ok
Thank you now I know how to proceed to make several connections work at the same time

Limitation of the connection method, i.e. sDongle only supports a single connection. Believe the new EMMA may support multiple connections though. Luckily with v1.4.x you have reconfigure this integration to point to a new IP (i.e. Modbus Proxy) without needing to uninstall and reinstall.
