March 25, 20251 yr Hi there!I am a new solar user, with a very limited, self-taught tech knowledge. I don't have a background in IT, and no knowledge of coding or more advanced computing like that. I've acquired a Sunsynk 5kva installation, and am trying to to build a smart energy network around that. From my research, I've decided to go for a Solar assistant setup, with home assistant managing my devices. I just purchased a pre-loaded SA Raspberry Pi, with RJ485 connectors etc. But immediately I've hit a snag. The Pi won't connect via WiFi or Bluetooth - only via ethernet. I've tried on/off on Pi, routers. I've tried reflashing the Pi with SA image file. All to no avail. Right now I don't have my inverter wired for ETH to the router, and that's gonna take me a while to be able to do that. Any help with troubleshooting the WiFi connectivity would be greatly appreciated 🙏.
March 26, 20251 yr Most lower end internet of things (IoT) devices like the Pi only work on the 2.4ghz frequency for WiFi. Do you know what frequency your wifi network is broadcasting on? Generally it would be either 2.5 / 5 or in rare cases 6 ghz. Check that first. If your router allows it - create a 2.4ghz only wifi network and try connecting the pi to that one
