1. The meter is installed and can connect to Wi-Fi and the Wi-Fi LED is on normally.
2. Once connected, it will be updated only for the first time and will not be updated again.

Hi:

From the photo, the WiFi led is off, which means the energy meter is not connected to the router now.

I guess the wifi strength is not strong enough so the connection is not stable.

Please try  this API when the WiFi LED is on, it will show the wifi strength by the "sig" value.
