As I remember, it broadcasts some production data on the Zigbee network, if it is configured. I was told the Zigbee connection would have used a Zigbee gateway to receive the production data and upload it to the SolarEdge servers; however, they also said the gateway was often problem.
Instead, when my inverter was installed, I used a hardwired Ethernet (since back then the inverter didn't apparently have a WiFi connection). I thought only Ethernet or Zigbee could be active.
I initially pulled my production data from the SolarEdge cloud API. I used the modified DTH from SmartThings (SolarEdge device type).
If I was setting this up today, I'd use @funzie's integration that you linked. This also talks to the SolarEdge cloud API:
However, since I installed my PowerWalls, I use the local integration with those to get my production data, since Tesla uses clamps to actively measure solar production.
Completely off Hubitat, I also use pvoutput.org to collect and track my solar production.
