Since most EG4 devices are made in China, is there any concern? Any way to check?

Yep. It’s been known for 3 years or so that they can shut them down through your WiFi that’s why I keep mine offline, but the new internal cell communication device is concerning to say the least. I guess that was their fix for folks like me 🤢

Aside from @pawnee's approach of disconnecting the WIFI dongle, I wonder if there are any other networking approaches that could be used to limit what domains the inverter can communicate with? Couple ideas:
- Router-Based Filtering
- Use a Pi-hole or DNS Filtering
Maybe @eric for @EG4 can chime in here on what are the valid IP adresses and domains our inverter should be able to communicate with.

Another thing @EG4 could do (ala @tesla) is to open source their software so we can get more eyes on what is being deployed to our systems.

@bobandroslyn I agree but this find was a cellular radio. It’s a bit concerning

I replaced the WiFi dongle with wired ethernet dongles. Am I a little more protected now?

Marginal at best. But you do the best you can. You have eliminated one avenue of access, no sense leaving the front door unlocked.
I too went the ethernet route. The deal breaker that pushed me over the edge, was the fact that the wifi kept losing signal and I would have to drive 60+ miles RT to reset. When your entire watering system is tied to signal availability; it matters a LOT!

From what I saw there was no proof they found anything. There were claims but no facts so without facts and verification it's just a boogeyman story and one most likely propagated, and possibly funded by the investor owned utility industry. See, boogeyman stories work both ways. Which do you believe because surely the utilities have not done anything in the past 20 years to limit rooftop solar and BESS installations. LOL
