Pro level current meter at a bargain price!

CuriousJoeJuly 12, 2025✓ Verified purchase

Fantastic current meter! The bonus is built in Ethernet! Small size will fit in tight spaces and easy install. Great function, except for some reason data download is not working right. There is also connection point for 1 more CT, but last I checked it is not sold separately. AND I wish there was short piece of DIN rail in box. Read more

Works great when integrated with HomeAssistant

DaveJanuary 2, 2026✓ Verified purchase

Great product generally, although there are a couple issues with the REST API if you're trying to write your own code to control it. Bad SSL certificate for https, and it rejects https requests anyway with a 443 error, yet it also does a strange redirect to https when you call http on port 80. I tried updating the firmware but issue remains. Integrated with HomeAssistant and called that API instead, which works great. Would be 5 stars if not for the odd issues with restful calls.
