I’ve bought an Eastron SDM230 modbus which I am going to connect to my Solax X1 mini through RS485 protocol. At the Eastron I connect a blue and white wire and i connect the cable with blue and white in a RJ45 which I connect to the RS port at the solax.
How can I get the information from the Eastron in HA? I saw some posts but most of them are using usb to a pi. I think it will be yaml but help it appreciated.
you need to buy a rs485/usb adapter and create a yaml to read the registers if you need it I can post it to you it works very well
Hi giangitangi, thanks for your reply . I have the eastron sdm230 directly attached to my inverter. No USB. So maybe I can use your script to get the parts I need for my setup. In your scenario you connect your sdm230 (connect white/blue) and the other end to a rj45 you plug in to the rs485 to usb to your HA?
A few weeks later and I am still in talk with Solax support. I noticed that in the web version of Solax you can set the modbuss address and modbus RTU enable. But I received errors because my inverter is running the base versions. I received firmware updates to manually upgrade my inverter so I am able to see the options within the inverter, but also there I receive errors. Friday I will have a phone call with Solax to look into it.
mine was also connected with Growatt inverter with two cables with the code it worked but I kept getting errors in the logs the sensors worked, I then discovered that it was the inverter that responded too for now I deactivated everything here is the code I hope it works with yours
