Maybe this is also of help for others
I've installed today Gen2 model of the Elli Charger Pro. All worked fine except the communication between evcc and and Elli. Evcc 0.131.4 runs on EL9 and HW is a 10 years old NUCi3.
Here's the typical evcc log when starting up:

After adding firewall-cmd --permanent --add-port=4712/tcp firewall-cmd --reload the connection issue was solved.
