Which WiFi dongle to use

I'm about to buy a luxpower inverter, which of these is supposed to work?

If compatibility with this local Home Assistant integration is the priority, I would choose the lower, standard “WiFi Dongle” (provided its connector is the one specified for the inverter model).

The important distinction is not really the case shown in the photo; it is whether the dongle exposes LuxPower's local TCP protocol. This integration needs:

• the dongle on the same LAN as Home Assistant;
• its 10-character serial number; and
• a reachable local TCP port (normally 8000).

The standard WiFi dongle is the established/safest option for that. E-WiFi can also work, but only when it is the non-encrypted/local-access variant. There are working reports for E-WiFi firmware 2.x, while dongles shown in the LuxPower portal as E-WIFI ENC (and some newer firmware) accept or immediately reset the TCP connection, so this integration cannot talk to them.

Before ordering an E-WiFi dongle, ask the seller/LuxPower to confirm in writing that:

1. it appears as E-WIFI, not E-WIFI ENC;
2. local Modbus/TCP access is enabled; and
3. port 8000 is available (or they tell you the configured local port).

After installation you can verify it before configuring HA with nc -vz <dongle-ip> 8000 (or Test-NetConnection <dongle-ip> -Port 8000 on Windows). An open port is necessary, though the final proof is that the integration can read the inverter model.

So, short version: buy the lower “WiFi Dongle” for the least-risk choice; buy E-WiFi only with an explicit non-ENC/local-Modbus guarantee and a return option.

Just came back here to share my experience.
I got the E WiFI Dongle and everything works great.
The reseller told that the encrypted version is generally only for industrial.
I have yet to update to the latest firmware which i hope it doesnt mess everything up
