Pro level current meter at a bargain price!
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.

Works wonderful in Home Assistant
Works great with Homa Assistant. Have 4 of these 2 are on wired ethernet and 2 on Wi-Fi. Not 100 percent accurate but very close. Wish there was a offset or calibration process. Note the voltage input is very small and somewhat difficult to connect. Home Assistant immediately identified the devices on the LAN and came online without issues. Entities include power W, Aparent power va, current A, Power Factor, Total active energy kWh, Total active return energy kWh, Frequency Hz, and Voltage. Also can reboot the device from Home Assistant, control the relay dry contact and update the firmware in the HA interface.

Works perfectly and easy to install / setup
Excellent product and easy installation. Allows me to monitor a remote condo and keep tabs on the HVAC and power consumption. The app is well polished and provides all the information and control you would expect with this device

Works great when integrated with HomeAssistant
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.

El medidor de energía funciona perfectamente y lo integre más fácilmente aún a home assistant. La conexión a la red wifi funciona muy bien inclusive dentro del panel eléctrico que es de acero.
