LAN connectivity is the reason I picked this over cheaper options, and it’s been rock solid for pulling live three-phase data into my dashboard every few seconds. The DIN rail mount clicked in place with zero fiddling, and the gen2 firmware handles updates without me touching a thing.

The LAN connection is rock solid so far, no drops since I wired it up last week. Setting it up through the gen2 firmware interface was way less painful than my old meter’s web config, which took half a day.

Installed it on the DIN rail in about ten minutes and the LAN connection synced with my home server instantly – the three-phase readings are spot on so far. The gen2 firmware menus are a huge step up from my old setup, and having it be DIN-mountable made the whole thing feel clean and professional.
