N20 Problem with Home Assistant Conection
#1
Photo 
Hello, I recently received an N20. I have access to it via Ethernet, but I can't connect it to "kinconyn20.local" nor can I connect it to Home Assistant. The strange thing is that it connects via MQTT from Home Assistant.

As soon as the device arrived, I flashed it to version v3 3.18.0. Its IP address is 192.168.3.78 (within my network range, OK), and its Wi-Fi access point is 192.168.4.1.

Is the problem that it can't access "kinconyn20.local"? Why doesn't Home Assistant recognize it?

I need to check the configuration of the CT clamps, as well as the L1 and L2 power inputs, which are not appearing.

I'm Spanish, sorry for the autotranslated English.

I followed the steps and I still can't connect it to Home Assistant. It appears in ESPHomeBuilder but with an error.

I can access the device via web 192.168.3.78 (dhcp) but never via kinconyn20.local. Why doesn't it work?

I´m thinking of returning the device

After trying many methods, I finally got it working, though not without some difficulty. I managed to connect it via USB to the Home Assistant server. No other method worked, and I tried many. Connecting via IP gave me a lot of problems and headaches; Home Assistant wouldn't recognize the IP address, even though the device itself was working. 

Now I'm struggling with MQTT. I can no longer access the device via IP. I can get the sensor data via IP, but not the configuration. I imagine this is related to Home Assistant.

I was about to return it... but we're going to keep fighting
