Yeah, I was thinking about using a "spare" Enphase IQ Gateway for this. We have a bunch of old Gateway 3 and 4 that we replaced with 5 to accommodate new battery installations. One of these used Gateways should suffice. I will try this with the Shelly suggestion that Glann made for long-term monitoring to make sure it keeps ticking.
