## Customer Reviews

### ⭐⭐⭐⭐⭐ It works!
*by I***U on 22 January 2024*

Needed to connect a solar inverter to hardwire to the net, so I could use home assistant.Works well, if it stops then restart your vm ( device running home assistant ) . Has been stable for couple of months now

### ⭐⭐⭐⭐⭐ Perfect for the job required
*by A***R on 18 November 2023*

I needed to connect my Solax PV inverter to Home Assistant, & wanted it wired rather than wireless. This did the job admirably for a reasonable price & has a good GUI.
