Access to device local web service through home assistant from remote

Hello to everyone,
I’m a recent happy user of home assistant. I installed the OS version on a Rasberry PI 3b and everything is working like a charm.

Due to a problem with my PV inverter, I need to access directly to its web service which is in a local network where my HA device is connected too. I’m working from remote thanks to a personal domain and Cloudflare tunneling services.

I was wondering if it could be possible to navigate (e.g. through a browser-like add-on) to my local network devices web service using HA as intermediate.
Expoiting CloudFlare services, I’m using https protocol, while the local web services are using http (hence the solution using the HA browser card doesn’t work).

Thank you in advance
