An important change regarding Enphase Auto Uploader systems

Hi @madbrain thanks for your post above. Out of curiosity I did a packet capture of traffic to-from the Envoy-R for a fifteen minute period. Within that period there was only one TLS session with a host 3.211.77.50 and a substantial transfer of data.

There were also a couple of brief http exchanges with very little payload.

Seems like that HTTP plaintext payload is just checking for web access to the Enphase website. The Envoy-R LCD displays shows “+Web” or “-Web”, likely based on this. Perhaps the frequent connections to the web site are solely to update the front display frequently enough, and not to transfer any micro-inverter data. Still weird they are using plaintext for this, though. Good that they are using TLS for the rest, though not for us trying to get access to the data.

I wish the “Lifetime generation” field on the Envoy-R home page showed kWh and not MWh. Would help with HomeAssistant integration a lot. Talk about a sawtooth graph when the data for the “Lifetime energy production” sensor in HA only increases about once a month.

We now have a signed agreement. See original post update for details.

WOO!! That’s wonderful news! :partying_face:

I can’t express how happy I am that everyone was able to work out an amicable solution. Good things still can happen in this world.
