I have a 1PM Mini Gen3. I do see it on my wifi networks, I can connect to it, but I can't access the web interface on http://192.168.33.1. any idea how comes?
And you are familiar with IP addresses and know that your network is in fact on 192.168.33.x?
If not, then your problem is that your Shelly device has gotten a different IP based on your networks IP range.
You need to find the new IP it has been given (via your router or a network scanner), and use that instead
