Comment Re:Same thing happened to my Enphase solar gateway (Score 1) 48
I used a local Envoy as well from 2010 to 2022 . It worked fine in Home assistant locally, as you say. I never blocked it from the Internet, however. My understanding is that the internal memory may fill up eventually, if it is unable to upload all its data to the Enphase cloud servers. I don't know how likely that is. I had 28 micro inverters in 2010. I did major expansions after that, adding two IQ gateways and 42 IQ8+ in 2022. The original Envoy did not work well in combination with the two IQ gateways on one site. Enphase replaced it at no cost with an Envoy-S. I now have all 3 connected, and working great in Home assistant. Except that all 3 require cloud.
My understanding is that the Envoy-S, when originally released, still allowed local access. Not certain about the IQ gateways. Enphase changed it at some point in a forced firmware upgrade. At the point I got my Envoy-S and both IQ8+, I believe they might already have been cloud only. Nevertheless, the result of all this is that I no longer have local access to monitoring for the 28 panels I put up in 2010.
