There's a mention that the local API issue (i.e., need the internet to get a security token to access local devices, so local access is toast if the internet is down) will have a work-around by the end of January by putting the Envoy in the AP mode.
I wonder if it isn't time to put in an alternative monitoring system?
Ran across a Shelby dual CT wifi port monitor, video
here.
$62 on Amazon. Seems great if you only need to monitor a couple of lines.
Iotawatt seems to have gone under, their web site is still active, but it's no longer available on Amazon. The
Emporia Vue doesn't have local access, so it won't work. The
Sense isn't really setup for something like this. The Shelby should work, but I need five CTs (L1/2 into the house, L1 from the panels, L1 from the generator, and L1 from the batteries) so that gets expensive. It would be nice to measure the SoC of the batteries, but guestimating through the current is probably the best I can do.
While I'd prefer to buy COTS, I could get an
ESP-WROOM-32 (WiFi MCU with analog pins) and
split core current transformers for just over $100 which is a lot cheaper than 3 Shelby's. Of course, the Shelby's are very small...so there might be advantages to putting one in the Envoy and two in the Enpower (guess I should start using the new names... the
IQ system Controller).
I'll probably wait until next month, already busy with other projects and who knows, perhaps Enphase will realize that devices already encrypted, using a non-routable IPs, that are behind a firewall are secure enough and give us the option to turn it off.
