So, took the plunge and ordered the [Waveshare RS485 to PoE Ethernet Module](https://www.tinytronics.nl/en/communication-and-signals/serial/rs-485/waveshare-industrial-serial-server-rs485-to-poe-ethernet-module) and had some time today to hook it up and configure it. I connected both my Growatt 3000TL3-S inverters to the module and after some fiddling on the Inverters (Giving each a unique ID) and in the module’s settings I got it working! Here the settings that work for me: ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/d/7/d757b018601d1517dbfc3263a7ac329ca0945f89.png) I made the following changes that differ with de module’s default settings: **Network Settings** - **Device Port** , set it to _502_ - **IP Mode** , switched it to _DHCP_ (Obviously made a reservation in my router) **Multi-Host Settings** - **Protocol** , switched it to _Modbus TCP to RTU_ - **Enable Multi-host** , switched to _Yes_ - **Instruction Time out** , was automatically set to _256_ after saving the **Protocol** and **Enable Multi-host** settings. It seems not all information from my inverters is handled correctly, I’ll monitor that and make a separate post for that. --- _[View the full topic](https://community.homey.app/t/app-pro-solaredge-growatt-tcp-modbus/45487)._
