I'm not sure whats going on with the networking, I had this working recently and now its stopped. I've reloaded the latest hydrosys image on my pi4, so starting from scratch, and I've changed the default IP address to match my LAN range.

The only way I can connect to hydrosys now is by connecting my wifi to the hydrosys AP. If I'm only connected to my LAN then I can't even ping hydrosys, even though I'm on the same range. Wifi is currently set to enabled so the wifi stays on. In the install documentation it says that if wifi is set to disabled then the AP will stay on for 3 minutes, turn off and I can then connect via ethernet, but this doesn't appear to be the case.

What I would ideally like to do is connect via the pi4 ethernet, not wifi. I added the ssh file to the boot partition and SSH is enabled, and using putty I can get a login response from the pi4 via SSH (as long as my wifi is connected to hydrosys) but I cannot login. I've tried the default username/password as pi/raspberry but it won't log me in.

If I can setup the ethernet I'll just ignore the strange wifi behaviour, but I need to be able to login via SSH to do this. Is there a different default username/password I can try?

Thanks,

Will.
