Solis RAI-3K-48ES-5G & S2-WL-ST stick

[Ian-Johnston]

Hi,

A real big THANKS for this HA integration.

It seems to be working with my RAI-3K-48ES-5G battery only inverter and my S2-WL-ST stick......using the HYBRID config which obviously give a few sensor issues.

The only other issue I am seeing is that when the integration in HA connects locally the soliscloud.com connection stops.......I am guessing because my S2 stick does not have Server B capability......?
Currently trying to find an older type stick that should hopefully allow both.....but this is proving hard! Any ideas?

Ian.

Yes, your dongle has no server B capability and you will struggle to find one that does I think.
A good option is this one if you are happy to spend a little and do some wiring: https://github.com/alienatedsec/solis-ha-modbus-cloud
This is my implementation of it and it works perfectly with the solis_modbus integration: alienatedsec/solis-ha-modbus-cloud#24

Going to try a USR-TCP232-410S device which allows multiple TCP connections to a single modbus connection.Not sure if SolisCloud.com can connect to it, really depends on what is ‘special’ in the existing sticks that allow SolisCloud.com to connect, or how configurable the USR is. Simple solution if it works.Failing that, I have a few of those Waveshare converters in use already on my network for some temp/humidity sensors so can try that after.Ian Ian JohnstonOn 10 Feb 2025, at 09:02, 0rangutan ***@***.***> wrote: Yes, your dongle has no server B capability and you will struggle to find one that does I think.

Waveshare modules configured and added. Working good.
